Cultivation Methods and Key Technical Points for Sugarcane Seedlings
1 Plastic Film Mulching Cultivation Techniques for Newly Planted Sugarcane 1.1 Fine Land Preparation Plow deeply 25-30 cm with an ox plow or tractor, achieving two plowings and two harrowings. Then open planting furrows with an ox plow or by hand at a row spacing of 90-100 cm, with a furrow depth of 23-25 cm. At the same time, to prevent future waterlogging from rain, drainage ditches should be opened around the sugarcane field, with a ditch...
Sugarcane seeds are tiny and contain few nutrients, so they cannot be sown directly in the field; seedlings must first be raised. The soil for sowing should be loose and fertile, and should be sterilized to kill soil-borne pathogens and weed seeds. When sowing, it is generally appropriate to have 150 seedlings within 30 cm x 30 cm. After sowing, cover thinly with fine soil, water until thoroughly moist, and cover with plastic film to keep warm and retain moisture. In terms of management, on the second day after sowing, the indoor temperature should be kept between 30-36°C; after the seeds begin to germinate, the indoor temperature should be kept between 25-30°C; germination is basically complete about 10 days after sowing. To keep the soil moist, spray water once in the morning and once in the afternoon each day during the seedling stage. When the seedlings are 6-10 cm tall and have 3-5 true leaves, they can be pricked out. There are generally two methods of pricking out: pricking out in nutrient trays and pricking out in seedbeds. When pricking out, the seedlings should be kept with soil, the leaf tips of the seedlings should be cut off, and after planting, water thoroughly to settle the roots so as to increase the survival rate. After the seedlings have been pricked out for 25-30 days, when tillering appears and the root system is relatively well developed, they can be transplanted to the field on a cloudy or rainy day.
