At present, sugarcane has entered an extension period. It is particularly important to grasp the management of sugarcane cultivator during this period, which is the key to seizing the high quality and yield of sugarcane.
Guide top dressing
Since June, sugar cane has entered an extended period, and the demand for water and fertilizer is large. Therefore, it is necessary to re-apply the elongation fertilizer. In late June to early July, when combined with cultivators, 50 kg of compound fertilizer for sugarcane and 20-30 kg of urea can be used to ensure the growth of sugarcane.
Do a good job of flood control drainage
Due to continuous rainfall, the groundwater level is high, or the low-lying sugarcane area is easy to accumulate water, and it is necessary to dig the drainage ditch deeply to avoid waterlogging in the sugarcane field.
Directing weed control
Sugarcane seedlings are long, wide row spacing, easy to breed weeds, the general weeding should be combined with cultivator. In areas where there are few people and labor shortages, weeds should be used for chemical weeding. When sugarcane soil is used, 80% can be used to wipe out 200g/mu, 80% diuron 200g/mu and other cane field herbicides to spray 45-60kg of water, spraying cane and field edge angles. Can block all kinds of weeds, pay attention to spray when spraying must be reversed.
Scratch pest control
The pests that damage sugarcane are: borers, aphids, thrips, scarabs, head smut, tip rot, brown strip disease, rust, etc. They should be combined with cultivating management to strengthen the control of pests and diseases. Underground pest control: 5% chlorpyrifos granules 3 kg/mu, carbofuran granules 4 kg/mu can be used, combined with topdressing and soil application to effectively control underground pests such as bark turtles, weevils and termites. The harm. Foliar pest control: Into the elongation of sugarcane, is a high incidence of cotton aphid mites, puffer horses, to focus on prevention. 50% can be used to reduce fog 15g/mu, foliar spray 60 kilograms of water to prevent cotton aphids; in the beginning of the sugar cane thrips, with 70% imidacloprid or acetamiprid water dispersant 8000-l0000 times liquid heart Leaf Spray Controls Sugarcane Thrips. If it rains after spraying, it should be filled after sunny weather.
Pay attention to safe production
Due to continuous rainfall, in the high-temperature and high-humidity climate conditions, it is prone to prevent poisoning when topdressing chemical fertilizers and pesticides.
