Building infrastructure in the wizard world

Chapter 332
When Mizutani saw the sugar cane in Shan Chengzhou's hand, he knew that it was not so easy to serve.

But after listening to all of Kong Wenhua's words, he realized that this thing is so difficult to serve.

"After the land preparation, you can start planting sugarcane furrows." Kong Wenhua explained, "Planting sugarcane furrows allows sugarcane to be planted to a certain depth, which is easy to manage. This is also the difference between sugarcane and other crops."

The width and depth of the cane ditch should be adapted to local conditions.According to the flat and wide landform of the camp, generally about 20 cm deep is enough, and the width of the ditch bottom is 20-25 cm, and the ditch bottom should be flat.

"Then you can plant the seeds directly?" Mizutani asked.

"right.

It would be best if we could choose new cane plants that grow better in the field as seeds.

Because the newly planted cane has strong growth stamina, there are more soluble nutrients in the cane tip, and the cane buds have strong germination ability.

If the seedlings are insufficient, the root cane can also be used as seeds.After selecting the reserved fields, water and fertilizer management should be strengthened in the later stage of sugarcane growth, so that the cane tips can absorb sufficient water and nutrients, which is conducive to the germination and growth of sugarcane buds after sowing.Strain selection is carried out at harvest time.

Select upright, thick-stem, and unflowered cane plants as seeds; remove mixed varieties to ensure the purity of the improved varieties. "

After all, Kong Wenhua looked at Shi Hao, and then at the World Book in Shi Hao's hand.

Of course Shi Hao had no objection and let Kong Wenhua continue.

"The next step is to cut the seeds.

Sugarcane seedlings are divided into single-sprouts, double-sprouts and multi-sprouts due to the number of cane buds.

We should use double-sprouts in production, and do not or less use single-sprouts and multi-sprouts.

Because of the apical dominance of multi-bud seedlings, generally the upper buds germinate first, and after the upper buds germinate, they will induce the production of auxin, which will inhibit the germination of the lower buds.resulting in uneven germination.This phenomenon, the more the number of buds, the more serious it is.

As for single-sprout seedlings, although there is no influence of apical dominance, since both ends of the buds have cuts, they are prone to hazards such as drought and water loss, so they should not be used.

Finally, double-sprouts do not have these problems. Their apical dominance is not as serious as that of multi-sprouts, and there is a complete internode in the middle of the seedlings, which is not as easy to lose water and other hazards as single-sprouts.The germination rate is high and the germination is relatively neat. "

Hearing what Kong Wenhua said, Shi Hao and Shui Gu nodded repeatedly.

Although Shi Hao didn't understand, he nodded again and again because he really admired Kong Wenhua's extensive knowledge.

But Mizutani really understood.

"The treatment of seedlings is still the same as sugar beets?" Mizutani asked.

"No, no, no. Drying seeds may be the same, but soaking seeds for disinfection and germination are somewhat different." Kong Wenhua said.

Shui Gu and Kong Wenhua communicated, Shi Hao and Shan Chengzhou looked at each other.

Shi Hao: Did you understand?

Shan Chengzhou: Didn’t you understand it too, what are you proud of?
"The seed soaking treatment of sugarcane only needs to make the sugarcane seedlings absorb enough water to transform the seedlings from a relatively dormant state to an active state and promote the germination of the seedlings.

We usually soak the whole bundle of sugarcane seeds in clean water for 1 to 2 hours, then pick them up, peel off the leaves, and chop the seeds.

The germination of sugarcane generally uses two kinds of stacking method and composting method.

Choose a place that is leeward, sunny, and close to the water source. First, spread a layer of semi-decomposed fertilizer about 10 cm thick, then put a layer of 20-25 cm thick seedlings, then put a layer of fertilizer, and then put a layer of seedlings .

So repeatedly, pile up 3 to 4 layers, the height of the pile is about 1 meter, the length and width of the pile are about 1.3 meters, and a layer of 10 cm thick manure is covered around the pile, and then covered with straw, sugarcane leaves, mud or plastic film to Maintain the temperature in the heap.

The humidity of the compost should be controlled so that it does not form a lump in the hand.

After sealing the pile, it is necessary to check the temperature and humidity in the pile frequently. The temperature should be controlled at about [-] degrees, which means it feels warm to the touch but not too hot.The degree of germination should be based on the protrusion of the root point.

As long as the beard roots are avoided, germination is considered a success.

The time required for germination is about 3 to 5 days.For the seedlings that have been germinated, the sugarcane field should be kept moist when planting. If the soil is dry, the germinated roots and shoots will lose water and dry up, and the emergence rate will decrease instead. "

No one would tell Mizutani these little tricks before.

So when Kong Wenhua mentioned it, Mizutani nodded repeatedly, as if he had known a confidant for many years.

"How long has it been planted? How much? How to manage?" Mizutani asked questions again and again.

"According to the current situation in our camp, early planting should be able to grow early and quickly. As long as we make full use of the high temperature and humidity growing season and prolong the growing season, we can increase the plant height and stem thickness, creating conditions for high yield.

As for planting density, it is closely related to sugarcane yield.

If the planting is too sparse, the number of effective stems will be small and the yield will not be high.If it is too dense, the plants will be weak and the stems will be thin, the dead stems will increase, the sucrose content will be low, and the sugar yield per mu will not be high, so you may need to think carefully about this.

After all, this is a time that has never happened before.

As for field management, it is even simpler.

Like rice and others, as long as the sugarcane seedlings are guaranteed, high yields can be obtained.

If there is a mistake, just do a good job of checking the seedlings and replenishing the seedlings.

During the seedling replenishment period, if the germination is basically over and the sugarcane seedlings grow 3 to 5 true leaves, if the missing plants are found to be more than 50 cm long, the seedlings should be replenished in time.

Another is to pull out too many tillers, reduce nutrient consumption, make the distribution of cane plants reasonable, and grow robustly.

The principle of removing tiller can be summed up as five to five to stay, that is, to get rid of the weak and keep the strong, to get rid of the dense and keep the thin, to get rid of the late and stay early, to get rid of the disease and stay healthy, to get rid of the shallow and stay deep.

In operation, a combination of stability and ruthlessness is required.

The stability mentioned here is to know what you know, and at the same time leave room for it.That is, according to the growth status of sugarcane and the level of water and fertilizer management, the effective number of stems per mu is determined.On this basis, about 15.00% more seedlings are left, and at the same time, the number of seedlings that should be kept per 1 meter of row length is generally calculated.

Ruthless means that after determining the number of seedlings that should be kept, the excess parts should be resolutely thinned, so as not to consume nutrients in vain and affect growth.

Generally, it is good to combine with large soil from the end of sugarcane splitting to the beginning of elongation.

Needless to say weeding, you only need to cooperate to kill the weeds, and the rest need not be said.

As for the watering of sugarcane, as long as the law of water demand of sugarcane is mastered, it is also very simple.

Sugarcane needs a lot of water throughout its life, but it is not resistant to waterlogging. The general trend of water demand is less at the two ends and more in the middle.

In the budding stage, seedling stage and mature stage of sugarcane, the water demand is less, and the water demand is large in the elongation stage.

Therefore, sugarcane fields should be kept in a wet-wet-wet state.

The amount of rain in the camp is particularly high, so irrigation should be strengthened.

In addition, sugarcane is not resistant to waterlogging, and water in the sugarcane field will cause rotten roots, so we need to drain water in time.

And with the elongation of the cane stem, the base leaves gradually wither and turn yellow from bottom to top, and the withered and yellow foot leaves are removed in the later stage of sugarcane growth, which has the effects of increasing yield, promoting ripening, and increasing sugar. "

"Brother Kong, listening to your words, I feel that this life is wasted." Shui Gu said while holding Kong Wenhua's hand.

"I'm talking on paper after all. If I want to talk about a real hero, I still want Mizutani to kill you, a person who is on the front line." For the first time in his life, Kong Wenhua felt that heroes cherished heroes.

Just at the same time that Mizutani and Kong Wenhua cherished each other.

Shan Chengzhou glanced at Shi Hao.

"Who planted it?" Shan Chengzhou asked.

Shi Hao saw Shan Chengzhou's eager expression, but waved his hand.

"You have more important things, and you have to find a professional to do this."
