Problems solved by technology

Because the cotton plants growing in the field are dense and clustered, it is impossible to use machinery to transplant rapeseed. Manual transplanting and watering are labor-intensive, cumbersome and inefficient.
At present, a large number of rural labor forces are moving to the cities, and it is difficult for the old, weak and women laborers who stay in the countryside to complete the arduous task of transplanting rapeseed after cotton. For this reason, most cotton farmers give up planting rapeseed and other crops after cotton harvest. land is left unused

Embodiment 1

[0030] In mid-May, select the short-season cotton variety China Cotton Institute 425, machine-sown cotton fields, after the cotton is harvested, the cotton stalks are mechanically recycled in mid-November, crushed and processed into sawdust-like powder of 0.3cm-0.5cm, piled into 2m high and 3m wide , 20m long strip pile, the pile surface is covered with plastic film, tied tightly around, and steamed for 5-10 hours for disinfection.

[0031] In mid-December, select virus-free potato seeds and cut them into small pieces of 25-30g. Each piece should retain more than one sprout eye. Use seed coating agent to spray disinfect the potato cubes, or select virus-free miniature seed potatoes for special use in potatoes The planter, at the same time, add fertilizer to the fertilizer storage box of the planter, start planting and cover with cotton stalk powder, and the appropriate cover thickness is 10-20cm.

[0032] After the potato emerges, spray with Ningnanmycin according to the prescribed...

Embodiment 2

[0037] At the end of April, the seedling substrate was mixed with peat+perlite+clay in any ratio, and the short-season cotton variety Zhongmian Institute 50 was selected. The seedlings were sown in plastic trays with a planter, and the seedlings were cultivated by heat preservation. At the end of May, the field was machine-planted.

[0038] At the end of November, after the cotton is harvested, the cotton stalks are collected and crushed to grow 5-7cm powdery objects. Fermentation bacteria and urea are added according to the prescribed amount to form a 2m×3m×10m strip pile, which is covered with plastic film, one week later Turn the pile once, and then turn the pile every 5 days until the temperature in the pile drops to close to the atmospheric temperature.

[0039] In mid-January of the following year, select early-maturing and virus-free potato varieties with a growth period of ≤80 days, cut into about 25-30g potato pieces, dress the seeds with calcium-magnesium-phosphate fertili...

Abstract

The invention relates to a cotton-potato cultivation method and belongs to the field of agriculture. According to a traditional planting mode in cottons areas in the south, cotton and rape are interplanted, since the labor intensity is high and the economic benefit is low, in recent years, most cotton farmers give up planting of succession crops including rape after cotton harvest, and then land is idle. A novel light and simple cotton-potato cultivation method for planting potatoes for one season at the idle land after cotton harvest comprises the steps that when cotton harvest is over, cotton straw is collected, smashed and disinfected, and potato seeds are spread on the cotton land and covered with cotton straw powder; when the potatoes are ripe, the potatoes can be picked up and harvested simply by opening the cover object. Compared with a traditional potato planting method, land plowing, potato digging and other procedures are simplified, labor intensity can be greatly reduced, and income of the cotton farmers is increased.

Description

Technical field [0001] The invention relates to a cotton-potato cultivation method, belonging to the field of agriculture. Background technique [0002] The traditional planting method in the southern cotton area is cotton-canola interplanting. In order to compete for the season and time, the cotton plants continue to grow in the field before the cotton harvest is over. Manually drilled into the gaps between the cotton plants to transplant rape seedlings to achieve cotton and rape interplanting. To improve economic efficiency. Because the cotton plants growing in the fields are densely clumped, mechanical transplantation of rape cannot be used, manual transplanting, watering and other labor intensive, complicated procedures, and low efficiency. At present, a large number of rural laborers are shifting to cities, and it is difficult for the old, weak and female laborers left in the countryside to complete the arduous task of transplanting rapeseed after cotton. For this reason, m...
