Hilling sugarcane because the sugarcane stem borer (stalk borer), besides harming sugarcane seedlings and causing deadheart seedlings, also bores into and damages the sugarcane stalk, forming "broken-head cane", seriously affecting the yield and quality of sugarcane. At this time, the residual period of the pesticide applied earlier has passed, and it cannot effectively control the sugarcane stem borer damaging the stalk, nor can it control pests such as sugarcane woolly aphid and thrips that occur in the middle and late stages of sugarcane growth. At this time, hilling sugarcane with 5 kg per mu of 3% carbofuran granules can effectively control late-stage sugarcane pests, protect the sugarcane root system, and promote sugarcane thickening and elongation.
Hilling sugarcane can also loosen the soil, helping sugarcane grow a healthy and well-developed root system. Sugarcane jointing is the most vigorous period of sugarcane growth and also the period when nutrients are most needed, while the nutrients of the base fertilizer applied at planting (or ratooning ridge restoration of ratoon cane) are supplied for absorption by sugarcane during the seedling stage and tillering stage, and the nutrients needed for growth during the jointing stage mainly depend on topdressing supplied with hilling. Therefore, hilling sugarcane is quite necessary. Hilling sugarcane can be carried out by referring to the following methods:
Small hilling Carried out when the seedlings have 6-7 true leaves and tillering appears. A hilling height of about 3 cm helps root development and promotes early tillering.
Medium hilling Carried out at the peak tillering stage, when the sugarcane plants begin to close the rows. A hilling height of about 6 cm has the effect of promoting growth.
Large hilling Carried out at the early elongation stage, with a hilling height of 20-30 cm. The effects are:
1. Let the basal nodes contact the soil, induce new roots to grow out, form a larger root system, enhance absorption capacity, and promote rapid elongation of the aboveground part;
2. Inhibit the occurrence of late tillering and prevent lodging. Note: Remove the basal foot leaves so that the root points contact the soil. Hilling can also play the role of intertillage and weeding, and should be carried out in combination with topdressing.
