Cotton Planting Knowledge (Six) Cotton Intercropping Pattern

< p > cotton and watermelon > a href= "http://www.91se91.com/news/" > interplanting < /a >, the two crops have a long period of symbiosis and before flowering, and watermelon is a vines, not with cotton.

As watermelon is fresh fruit, special attention should be paid to prevent pesticide pollution, reduce chemical control of pests, and select high efficiency, low toxic pesticides or biological pesticides.

< p > the planting pattern is generally about 3 meters wide, and the size of the cotton is planted. The row spacing is 150 centimeters, the small row spacing is 50 centimeters, and the row is 4 rows of cotton.

The watermelon is pplanted to the cotton rows in the sides of the border. A row of 2 rows of watermelon is planted. The plant spacing is 40~50 centimeters, and 500~600 plants can be planted in each mu. When pplanted, the mulching film will increase the temperature and moisture, promote the early increase of production, lead the watermelon vine to the big cotton row, the vine grows relatively, and grows in the big row.

Cotton seedling pplanting, 1800~2000 mu per mu.

From late June to early July, watermelon harvest came on the market, yielding 2000~2500 kg per mu, 80~100 kg of cotton per mu, 3000~4000 yuan of Mu output value and 2000~3000 yuan of net income.

< p > choose good varieties of watermelon to select early maturing varieties such as Kang Su Su and Su Mi No. 1, and choose hybrid cotton varieties with strong growth potential and suitable for sparse planting, such as suza 3, cmian 3, Nong 6 and Sikang 3.

< /p >

< p > suitable season for watermelon harvesting and sowing in late March, pplanting in April 20th and leaving the field before the end of June.

Cotton was sowed in early April and pplanted in mid and late 5.

< p > scientific fertilization.

Watermelon should be applied to basic fertilizer, and organic fertilizer should be applied to the cotton rows. The quality of the soil is 1000~1500 kg, 20 kg of urea and 50 kg of cake fertilizer per mu.

During fruit setting, fruit fertilizer was applied, and 15~20 kg of urea and 8~10 kg of potassium sulfate were applied per mu.

Two crops have sufficient nutrients in the field during the symbiosis period. Cotton is usually not fertilized at the early stage, but also should be kept under control.

< p > strengthen the management of watermelon extension and vine stage, often prune the vine, so that the watermelon vine can be evenly distributed. When the watermelon is harvested, it will burrow the stems and leaves in time, and the cotton will be ploughed up and blocked up, so as to make the small ridge high and prevent lodging.

< p > commonly used cotton < a href= "http://www.91se91.com/news/index_c.asp" > field interplanting > /a > planting mode cotton and Potato Intercropping mode < /p >

< p > cotton and Potato Intercropping Pattern has a large application area in Yancheng. The two crops have a long symbiosis period, and have little interaction in the symbiosis period, and have complementary effects on fertilizer utilization.

At the late growth stage, the potato is rich in water, which is beneficial to the emergence of cotton seedlings, and can get double high yield of cotton and potatoes. The average yield of potatoes is 2000~2500 kg, the yield of cotton is 80~100 kg, the output value of Mu is 2500~3000 yuan, and the net income is 1500~2000 yuan.

< p > General border width of 3 meters, cotton size row planting, large row spacing of 150 cm, small row spacing 40 cm, a row of species 4 rows of cotton.

Potatoes are usually planted in large cotton rows in early February, with a row spacing of 75 cm, 2 rows of potatoes planted in rows, and 15~20 cm spacing, 3500~4000 mu per mu.

Cotton seedlings were pplanted and planted on both sides, with 1800~2000 plants per mu.

< /p >

< p > choose the improved variety.

Potatoes choose high yield, good quality, early maturity and virus-free seed potato, such as Ke Xin 1, Holland 15 and so on. The new cotton varieties with strong selection growth potential, strong individual yield forming ability and suitable sparse planting, such as suza 3, Kun Mian 3, Nong Nong 6, Sikang 3, etc.

< /p >

< p > sowing in good time, potatoes were sowed in early February, harvested in early May to early June, and left in the early June. Cotton was planted before April 10th and pplanted in mid May.

< p > < a href= "http://www.91se91.com > > scientific fertilization < /a >

Potatoes should be fertilized with basic fertilizer. Before planting, 2000~2500 kg of high-quality soil and 15 kg of urea and 10 kg of potassium chloride are applied to the cotton field.

Due to the sufficient nutrients in the field during the growth of potato and the application of its stems and leaves in the field as the base fertilizer, the fertilization should be properly adjusted during the growth period of cotton. Generally, no fertilizer should be applied in the early stage. At the same time, the growth should be controlled.

< p > strengthening management

In the middle and March of the year, potato was broken and released in the early stage of emergence. The tubers were watered during the expansion stage to keep the soil loose and water suitable.

Since potato is the host of the two generation of the blind bug, we should pay special attention to the prevention and cure of cotton blind.
