Cultivation and management techniques of planting sugarcane with high seedling quality under soil moisture in winter

Autumn rainwater accumulated in winter soil has not evaporated in large quantities, and planting under strong moisture is beneficial to sugarcane germination on hillsides without irrigation conditions; winter ground temperature is higher than temperature, winter sugarcane roots develop well, seedling quality is high, yield is high, maturity is early, and sugar accumulation is more.

1. Cultivation techniques:

1. Land selection and preparation:

Winter sugarcane planting in low temperature and drought season, in order to keep warm and moist, planting land conditions should be higher than spring planting, autumn planting, select irrigation conditions, no ponding, sunny, flat terrain, strong water retention capacity of the plot. The soil is required to be finely divided, the field surface is flat, the planting ditch depth is about 30 cm, and the row spacing is 90-100 cm. It is planted in paddy fields and tableland with good water conservation conditions.

2. Timely planting:

The sowing time of winter planting sugarcane is closely related to the safe overwintering, germination and seedling rate of seedlings. Early planting period, sugarcane bud germination unearthed, vulnerable to frost and death, not budding bud is also due to long-term low temperature and drought and rot; planting period is too late, once frost, but also vulnerable to frost rot. Sugar cane can generally be planted from early November to late December or mid-late January.

3. Cut down the seeds:

Winter planting sugarcane seeds, when low temperature and drought, high requirements for seedlings, cutting seeds, to select healthy disease-free sugarcane seeds, sugarcane seeds generally with 2-3 buds. Because germination time is long, the disease is more serious than spring and autumn sugarcane, and it is best to disinfect the cut seedlings with lime powder. When planting, deep ditch reaches soil layer, depth 30-35 cm, ditch bottom should be leveled to ensure planting quality. Winter planting sugarcane should increase the number of seedlings appropriately, planting 6500-7500 double buds per mu to ensure basic seedlings, after planting, the soil should not be too thick.

II. Field management:

Winter sugarcane planting period ahead of schedule, jointing ahead of schedule, so the field management measures to "early" as the center, must be in mid-May topdressing. Before tillering stage, timely fertilization can promote early tillering and more tillering, and improve tillering rate. Combined with intertillage and weeding, soil cultivation is carried out, and stem fertilizer is applied in the large soil cultivation. If the growth rate of sugarcane decreases in August and there is a lack of fertilizer, strong tail fertilizer should be applied. Winter sugarcane seedlings are the winter places for borers and aphids. It is necessary to prevent and control them early, eliminate the source of winter insects and prevent the spread of pests.
