After years of planting exploration, the following management methods of sugarcane planting are summarized for reference:
Timely fertilization
Fertilization combined with secondary weeding after emergence, dilution of fertilizer in the second field growth period combined with each soil tillage, timely application of foliar fertilizer and balanced fertilizer for the third time, and addition of new high-fat film for each fertilization can greatly improve the limited component rate of fertilizer.
Cultivate soil and transplant rice seedlings.
Generally, the soil should be cultivated 3~4 times a year, with an interval of about 30 days each time. At the same time, combined with soil cultivation, seedlings should be fixed in time and new high-fat film should be sprayed in time. On the surface of plants, it can prevent the infection of germs, improve the ability to resist natural disasters, improve the intensity of photosynthesis and protect seedlings from growing sturdily.
Reasonable irrigation
Fruit cane needs a lot of water, so we should pay attention to irrigation in time, but we should avoid big water irrigation, advocate light water irrigation, keep the soil dry and wet, mainly wet, and spray Zhuangganling in time, which can make the stem thick, the leaves plump, the color fresh and tender, the plants lush and the natural flavor rich. At the same time, it can improve the disaster resistance, reduce the dosage of pesticides and fertilizers, and reduce the residual poison.
Stripping leaves
After the sugarcane plants are elongated, they begin to peel the leaves, 3~4 pieces at a time. Too many leaves will affect the growth of plants, and peeling will not affect flour in time.
How to hybridize
First of all, we should check the fertility of sugarcane ear pollen. Parents with good pollen development are generally used as male parents, and parents with poor pollen development are generally used as female parents. Before hybridization, the female parent should emasculate to avoid self-pollination; When crossing, the male parent should be placed above the female parent, and the pollen of the male parent is easy to fall on the stigma of the female parent, which is easy to cross successfully; When the air flows, sugarcane pollen is easy to drift away. In order to prevent other male parents from escaping pollen, it is necessary to make a new house for the "groom" and "bride" with dense and breathable white cloth before cross pollination. Sugarcane hybridization usually takes 7 days. In order to improve the pregnancy rate, it is necessary to shake the male parent at 9 ~ 1 1 every morning, so as to facilitate the pollen to fall on the stigma of the female parent and improve the success rate of hybridization. Commonly used hybridization methods are: sulfurous acid method and high pressure method.
Cultivate sugarcane seedlings
Sugarcane seeds are small and have few nutrients, so they can't be sown directly in the field. First of all, we should raise seedlings. Sowing soil should be loose, fertile and cultivated to kill soil germs and weed seeds. When sowing, it is generally appropriate to control 150 seedlings in a hotbed of 30×30 cm. After sowing, cover the seedlings with thin soil, water them until they are soaked, and cover them with film to keep warm and moist. In management, the indoor temperature should be kept between 30 ~ 36℃ the day after sowing, and between 25 ~ 30℃ after seeds germinate, and seeds germinate about 10 day after sowing. In order to keep the soil moist, spray water 1 time every morning and evening at the seedling stage until the height of the seedling is 6 ~ 10 cm and there are 3 ~ 5 true leaves, then you can get the following. Follow-up method generally includes two methods: nutrition bowl follow-up and seedbed follow-up When transplanting rice seedlings, the seedlings should be covered with soil and the leaves and tails of the seedlings should be cut off. After planting, the roots should be watered thoroughly to improve the survival rate. 25-30 days after planting, when tillers appear and roots are developed, seeds can be sown in rainy days.
