Black sugarcane: how to manage planting black sugarcane?

How to manage the planting of black sugarcane? Please introduce the good management methods of planting sugarcane after years of planting and exploration, and sum up the following sugarcane planting management methods for reference: timely fertilization and seedling emergence combined with the first weeding to apply fertilizer, the second field growth period combined with each soil cultivation to apply diluent fertilizer, the third timely application of foliar fertilizer and balance fertilizer, and the application of new high-fat film in each fertilization. The limited composition rate of fertilizer can be greatly increased. Generally, soil should be cultivated for 4 times a year, each time at an interval of about 30 days. At the same time, combined with soil cultivation, seedlings should be fixed at the right time, and new high-fat film should be sprayed at the right time. On the plant surface, it can prevent bacterial infection, improve the ability to resist natural disasters, and improve the intensity of photosynthesis. Protect the seedlings from thriving. Rational irrigation of fruit and sugarcane requires a large amount of water, so we should pay attention to timely irrigation, but we should avoid flood irrigation, advocate light water irrigation, keep the soil dry and wet, give priority to moist, and spray Zhuangtuanling timely, which can make the stem stout, leaves thick, color fresh and tender, plants luxuriant and natural taste strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity. The leaf-stripping sugarcane plant began to peel leaves after elongation, peeling 3 or 4 leaves each time, too much leaf peeling affected the plant growth, and leaf peeling did not affect the pollination in time. How to carry out hybrid sugarcane hybridization first needs to check the fertility of pollen in flower panicles. Parents with good pollen development are generally used as male parents, while parents with poor pollen development are generally used as female parents. The female parent has to go male before crossing to avoid self-pollination; when crossing, the male parent should be placed above the female parent, and the male parent's pollen is easy to fall on the female parent's stigma, so that the hybridization is easy to succeed; air flow, sugarcane pollen is easy to drift, in order to prevent other male parents from pollinating, it is also necessary to use a dense and breathable white cloth to make a bridal house for the "groom" and "bride" before cross pollination. The hybridization time of sugarcane usually takes 7 days. In order to improve the pregnancy rate, the male parent needs to shake manually at 9: 11 in the morning so that the pollen can fall on the stigma of the female parent, so as to improve the success rate of hybridization. The commonly used hybridization methods are sulfite method and high pressure method. To cultivate sugarcane seedlings, sugarcane seeds are small and contain few nutrients, so they can not be sowed directly in the field. The sown soil needs to be loose, fertile and sterilized to kill soil germs and weed seeds. When sowing is generally controlled in 30 × 30 cm hotbed with 150 seedlings, thin cover fine soil after sowing, watering to wet through, covered with film heat preservation, moisturizing. In terms of management, the indoor temperature should be kept between 30 ℃ ~ 36 ℃ on the second day after sowing and 25 ℃ ~ 30 ℃ after seed germination, and the germination was completed about 10 days after sowing. In order to keep the soil moist, water can be sprayed once every morning and afternoon in the seedling stage until the seedling height is 6-10 cm and there are 3-5 true leaves. There are generally two kinds of pseudo-planting methods: nutrient plate pseudo-planting and seedling bed pseudo-planting. Seedlings should carry soil during pseudo-planting, cut off the seedling leaf tail, and drench the root water after planting to improve the survival rate. After 25-30 days of pseudo-planting, when tillering occurs and the root system is more developed, it can be planted in the field in overcast and rainy days.
