Sugarcane planting begins in the autumn of 2017. Sugarcane farmers must pay attention to these five points.

This year, the rainfall in autumn in sugarcane areas in China is heavy, the temperature is high, and typhoons occur early, so it is more difficult to manage sugarcane production. Now it is the time to plant sugarcane in autumn. So what should sugarcane farmers pay attention to when planting sugarcane in autumn in 2017?

01 water and fertilizer management

Autumn is the key period for the formation of sugarcane yield. In case of dry season, deep irrigation should be carried out every 10 days or so to keep the water content within 50 cm below the surface of the soil above 80% of the maximum water holding capacity. During this period, the demand for plant nutrients is also large, so it is necessary to apply fertilizer reasonably according to the conditions in the field. When leaves turn yellow, strong tail fertilizer should be applied as soon as possible, and 15 kg of available nitrogen fertilizer per mu should be applied to roots.

02 Disease and pest control

For sugarcane fields with serious occurrence of aphids and borer, combined with the prediction of insect situation, UAV can be used to spray pesticides in the air for centralized control. Decentralized control, select 50% aldicarb, 5 grams of water 10-15 kg spray to control aphids; select 20% chlorobenzamide suspension, spray to control borer according to the instructions. In sugarcane fields with serious occurrence of sugarcane tip rot, brown stripe and rust, diseased plants should be removed in time, seriously diseased leaves should be removed, old foot leaves should be removed, and ineffective and weak plants should be removed occasionally.

03 windbreak and disaster reduction

Typhoon damage in coastal areas is relatively serious this year, so we should do a good job in wind prevention and disaster reduction. To high soil, height of 30 cm, soil should be full in the shape of steamed bread. After the typhoon, the lodging sugarcane should be straightened in time and tied into a "human" frame to promote the normal growth of sugarcane.

04 drainage and waterlogging prevention

The rainfall of autumn planting in some sugarcane areas is large, so the field drainage should be done well. Drains should be built on the periphery of the sugarcane field. In the sugarcane field vulnerable to waterlogging, according to the topographical conditions, the drainage ditches with the shape of "cross", "Feng" or "well" should be excavated, and the water should be discharged to the outer drainage channel of the sugarcane field, so as to reduce the groundwater level in the field in time and reduce the waterlogging damage.

05 management of planting sugarcane in autumn

Sugarcane planted in autumn is generally planted from late August to early October. High-yield and high-sugar varieties should be used in production. To reasonably control the planting time according to the weather conditions, it is appropriate to plant 5000-6000 buds per mu. Apply sufficient base fertilizer, according to the growth of sugarcane, reasonably apply warm fertilizer for winter.
