When do sugarcane tillering seedlings be broken? Do you want to remove the main seedlings at the til

It can be broken before tillering to prevent unnecessary nutrient consumption.

After the early stage of checking the seedlings and filling the gaps, it was the tillering period of sugarcane in our land. Strengthening field management at the tillering stage is the key to improving sugarcane planting yields, and sugarcane farmers should do the following five specific tasks.

1) Apply enough tillering fertilizer. As the saying goes, "the mouth should be sucked, and the root should be fertilized", whether the fertilizer is sufficient or not is directly related to the number of cane seedlings and the growth of tillerers. Therefore, tillering fertilizer must be applied sufficiently, which can be applied at one time at the beginning of tillering, mainly with high nitrogen type of Strim Chong fertilization.

It is advisable to apply 10-15 kg of urea per mu or 10-15 quintals of thin human feces and urine, and ammonium carbonate is not conducive to the sugar storage of cane stems in the later stage, so it is generally advisable to apply less.

2) Cultivating and weeding soil. Due to the wide row spacing of cane seedlings, weeds breed quickly, and weeding is stricter than that of other crops. Weeding can be combined with cultivated soil, as little as possible with herbicides, the number of tillage depends on the degree of weed breeding and the degree of soil clay, generally not less than twice.

Soil cultivation can be combined with cultivating, generally in the base of the cane seedling height of 2-3 inches is appropriate, can promote tillering, but also can prevent the later cane stem lodging.

3) Seedlings and seedlings. In order to make the growth of cane stems uniform and consistent throughout the field, seedling determination should be carried out from the peak tillering period to the beginning of cane stem elongation. The seedlings should be weak and strong, dense and thin, late seedlings and early seedlings, shallow seedlings and deep seedlings.

The seedlings should be determined according to different sugarcane species, 5000-6000 plants per mu for large sugarcane seeds, 6000-7000 plants per mu for medium sugarcane seeds, and 7500-8000 plants per mu for small sugarcane seeds.

4) Prevention and control of pests and diseases. During the tillering period, borers, aphids, and embroidery spot disease are harmful to cane seedlings, so we should pay attention to the disease and insect forecasts of the local agricultural plant protection department at any time, and combine field management to achieve early prevention and early treatment.

5) Drought and stain prevention. In case of drought, drought should be fought in time, and ditches should be cleared and drained in time in case of waterlogging.

Sugarcane is tillered to 6 to 12 roots, and all of them are seedlings, and other tillers can be broken off or soiled.

In the tillering stage of black-skinned sugarcane, the main seedlings need to be removed in general. This is because the main seedlings of black-skinned sugarcane consume a large amount of lead grinding and water, while the resulting tiller seedlings are the main growth**. If the main seedlings are not removed in time, it will lead to the waste of nutrients and water, which will lead to the inhibition of the growth of tillers seedlings, and affect the yield and quality of black-skinned sugarcane.

In addition, removing the main seedlings can also promote the growth of black-skinned sugarcane, increase the number of tillers seedlings, help to increase yield, and can also make the growth of black-skinned sugarcane healthier. At the same time, removing the main seedlings can also make the black-skinned sugarcane better resistant to wind and lodging, which helps to improve the yield and quality of black-skinned sugarcane. Therefore, the main seedlings should be removed at the tillering stage of black-skinned sugarcane, which is conducive to ensuring the growth of tillering seedlings and improving the yield and quality.

Hello, I'm glad to answer for you. Black-skinned sugarcane needs to remove the main seedlings during tillering. This is because the growth habit of black-skinned sugarcane is mainly based on tillering, and the collapse of the main seedling will inhibit the growth of side tillers, resulting in a decrease in yield.

Moreover, the main seedling requires more nutrients and water, which will also cause a burden on the growth of the potato kernel of the whole crop. Therefore, the uprooting of the main seedling can promote the growth of side tillers, increase the yield, and at the same time make the plant shape more symmetrical and improve the economic benefits of sugarcane.

Hello, I'm glad to answer for you, in the black-skinned sugarcane tillering period, you need to dial off the main seedlings. The main seedling refers to the first seedling that grows in the process of sugarcane planting, because the main seedling grows strongly, if it is not removed in time, it will seize nutrients and water, and adversely affect the growth and development of the tardination and tillering. Generally speaking, the method of removing the main seedling is to gently pinch the junction of the main seedling and the tiller bud, and then slowly twist the main seedling to cut it off, take out the root of the main seedling, and do not pull the other tiller buds.

It should be noted that the time to remove the main seedlings should be carried out at the beginning of the growth of the tiller buds, so as not to affect the normal development of the tiller buds. At the same time, after the main seedlings are removed, the soil should be sorted out in time to keep it moist and promote the growth of tiller buds. The above content is for your reference.

Planting period: The growing period of sugarcane is mainly affected by temperature and variety, which is about 14 to 18 months in Taiwan, but the root can be shortened, only 12 months. Sugarcane with insufficient growth period not only has a low yield, but also has a lower sugar content. Autumn planting of sugar cane to.

In August and September, sugarcane is planted in spring.

February and March are the appropriate planting periods, because the start period of sugar production is from November to April of the following year, so autumn cane has enough growth period, and spring cane needs to be harvested later to cooperate.

Intercropping: Young cane grows slowly, and it is a pity that the land is not fully utilized, so you can intercrop other short-term crops in the first phase, grow together with cane seedlings, and harvest before the cane grows up, so as to increase the income of the land. However, there is a condition that needs to be observed, that is, the intercropping crops must not have too many adverse effects on the cane crop.

Suitable crops include sweet potato, peanuts, beans, corn, tomatoes, garlic, potatoes, melon seeds and watermelons.

Sugarcane: In a rotation system, it is usually one new planting, followed by two or three roots, then one or two rice roots, and then back to new planting. Before the rice harvest at the end of the stage, the newly planted sugarcane is planted in the paste-like soil between the rice plants, which is called paste-seeded sugarcane.

Its advantage is that it does not affect the growth of rice, but also enables the early planting of post-cropping sugarcane, and can also save the cost of land preparation and furrow construction. Intercropping with the first stage of rice is called the first stage of paste sugarcane, also known as spring planting paste sugarcane. Intercropping with the second stage of rice is called the second stage of paste sugarcane, also known as autumn planting paste sugarcane.

Green manure: Prepare for the autumn planting of the cane field, you can use the leisure time after the harvest of the previous crop to sow green manure, and plow into the soil before planting cane to ** organic fertilizer in the soil. Commonly used green manure crops include solar hemp, field claw and tiger claw bean.

Diseases: white leaf disease, striat, leaf blight, etc. As long as you have a disease, no matter what the disease is, there is no cure, you can only uproot the whole plant, burn it, and then pray that it will not spread, which requires diligent inspection, early detection, and rapid extinguishment.

A better way to prevent and control is to breed disease-resistant varieties that are not afraid of the virus.

Sugarcane seedlings can be left 3-4 in time, the excess is cut off in time to avoid the consumption of excess nutrients, when breeding sugarcane, the soil requirements are loose and fertile, deep soil layer and convenient drainage and irrigation type, in the sugarcane growth period needs to let it have sufficient water and nutrients, so that sugarcane can grow vigorously.

When breeding sugarcane seedlings, a sugarcane can be left 3-4, excess sugarcane seedlings need to be cut off in time, which can reduce the consumption of excess nutrients, which is conducive to the vigorous growth of the remaining sugarcane seedlings, and also need to pay attention to the source distance of sugarcane seedlings, otherwise if it is too dense, the ventilation and light transmittance of the plant will become low.

2. Soil requirements

Sugarcane has certain requirements for soil, when planting it, we need to choose a deep soil layer, loose and fertile soil and convenient drainage and irrigation plots for planting, before planting the soil needs to be deeply cultivated, but also need to apply enough basal fertilizer in the soil to improve the fertility of the soil.

3. Sufficient moisture

Sugarcane has a high demand for water, in the process of its growth, it is necessary to keep the soil slightly moist, so that sugarcane can grow vigorously, pay attention to the water required by sugarcane in different periods, the water required in the early and late growth period should not be too much, and when it is extended, it needs to be made with sufficient water.

4. Reasonable fertilization

The growth period of sugarcane is very long, in its growth period, it needs to make its hail send sufficient nutrients, so it is necessary to apply thin fertilizer regularly during the breeding period, so that sugarcane can grow vigorously, generally can be applied to fertilizer containing nitrogen, phosphorus and potassium elements, pay attention to fertilization can not apply thick fertilizer.
