When will sugarcane be planted in autumn and winter? How many seedlings are planted in an acre of land? How to plant it? (with technical guidance for late sugarcane production in 2018)

Recently, the Ministry of Agriculture and Village issued technical guidance for the late production of sugarcane in 2018, saying that in order to promote the high yield and high sugar of sugarcane, the National Agricultural Technology extension Service Center together with the sugar expert guidance group of the Ministry of Agriculture and Village gave a detailed introduction to the planting time and management skills of sugarcane in autumn and winter. When will sugarcane be planted in autumn and winter? How many seedlings are planted in an acre of land? How do you plant it?

First, control moisture

Sugar accumulation in sugarcane was promoted by controlling moisture. Water control should grasp the principle of "dry and wet", requiring the sugarcane field surface soil to be moist but not wet, dry but not white, and irrigation and drainage should be carried out in case of dry weather to avoid stagnant water in the field. In the areas with more rainfall in the later period, we should pay attention to the field drainage and dig drainage ditches in the periphery of the sugarcane field to lower the groundwater level. In the sugarcane field which is prone to waterlogging, according to the topographical conditions, dig the drainage ditch with the shape of "ten", "Feng" or "well" to drain the water out of the sugarcane field.

2. Peel off dead leaves

Peel off the dead leaves in time, improve the ventilation and light transmission in the field, and reduce the occurrence of diseases and insect pests. The fields with high humidity, stagnant growth and serious diseases and insect pests should be peeled, and the withered leaves should be taken out of the sugarcane field for centralized disposal. the standard of leaf stripping is 9 to 10 new leaves per stem. In sugarcane areas with serious diseases such as slight rot, brown spot and rust, 75% chlorothalonil wettable powder and 50% carbendazim wettable powder can be foliar sprayed once every 7 to 10 days and twice in a row to control the spread of the disease.

III. Wind prevention and disaster reduction

In the middle period, we should pay attention to the cultivation of soil, with a height of 30 cm. If sugarcane suffers from a typhoon in the later stage, the fallen sugarcane should be tied up in time. At the height of 2/3 of the sugarcane plant, two rows of sugarcane should be bundled into a herringbone with rope or dead leaves, or adjacent sugarcane plants should be tied into a bundle to keep the sugarcane upright and continue to grow. 15 days after the upright sugarcane resumes growth, untie the rope.

IV. Timely harvest

The harvesting of sugarcane is based on the principle of first harvest, late harvest and late harvest. For sugarcane fields that want to stay in the root, it is appropriate to cut down after "Greater Cold", which is beneficial to the germination and emergence of sugarcane buds. Harvesting and cutting should be carried out fast hoe and low chopping, 5cm into the ground for harvesting and cutting, reducing the sprouting position of persistent roots and reducing the rupture of sugarcane stakes.

Fifth, do a good job of planting in autumn and winter

1. When will autumn sugarcane be planted?

It is appropriate to grasp the next planting time for planting sugarcane in autumn, which is between late August and early October.

2. What kind of sugarcane should be planted in autumn?

In cultivation, the improved varieties with developed root system and uniform sugarcane with lodging resistance were selected to deepen the planting.

3. How many seedlings are planted in one mu of sugarcane in autumn?

To properly reduce and control the amount of seed, it is appropriate to plant 5000 to 6000 buds per mu, apply sufficient base fertilizer, and topdressing 20 kg urea per mu in December.

4. When will sugarcane be planted in winter?

Winter planting sugarcane is planted after the first ten days of November. After planting, attention should be paid to covering plastic film, increasing soil temperature and ensuring the normal emergence of sugarcane.
