In the late growth period of 2011, because the weather was continuously raining, resulting in a decrease in cotton production, and the price of cotton was also drastically reduced, the gross income per mu was 1,700 to 1,800 yuan, and the benefits of cotton farmers decreased accordingly. However, Li Yulan of Changzhong Village, Lijiabu Town, Cheng’an County adopted an intercropping pattern of cotton and mung beans. It received 530 pounds of cotton per mu, mung beans more than 50 kilograms, and gross income of about 2,400 yuan, 500 to 600 yuan more than single cotton. Now he will give you an overview of his management points:
1. Site preparation. The arable land will be carried out in mid-March, and 60 kg of special fertilizer for cotton will be applied to cultivated land. On April 20th, it became awkward. On the 26th sowing cotton (cotton varieties are best to use hybrid cotton varieties), the use of a single spacing planting mode, row spacing of 100 cm and other row spacing, spacing of 23 to 25 cm, mu density of about 2500, sowing herbicide herbicide after sowing After the pass, cover it with a 60 cm wide mulch.
After the cotton sowing, a row of mung beans is sown in the middle of the row spacing, with a spacing of 40-50 cm. For the mung bean, early maturing varieties such as Fulan 7 and Fulv 8 are used.
2. Set of farming management. After the emergence of cotton and mung beans, the seedlings were planted in shallow meddles in order to raise the ground temperature and promote the early growth of strong seedlings. Cotton was seeded at 3 to 4 true leaves. At the same time pay attention to control locusts and spider mites. In the first half of June, the harmfulness of cotton blindworms was controlled and the organic phosphorus pesticides were promptly sprayed and prevented when black spots were found on the cotton tip. Around June 10, mung bean was ripe. At this time, mung beans were harvested once and the soybean meal was removed.
3. Cotton field management.
1 In the early flowering period, the cotton topdressing urea 20 kg, and timely watering, timely cultivator after watering, is conducive to weeding and conservation of cotton and promote the roots of cotton under the bar, improve cotton resistance and lodging resistance. At the end of July and early August, 15 kilograms of urea was applied as a top-covering fertilizer to promote the formation of more bells on the upper part of the cotton plants.
2 The control was performed once at the initial flowering stage and once after the topping, respectively, 1 g and 3 g per mu. Since the row spacing of cotton is slightly larger, the control should be lighter, and the space in the cotton field should be fully utilized to make more bells.
3 The prevention and treatment of cotton bollworm should be sprayed at the peak of egg hatching period. The use of organophosphorus and pyrethroid pesticides can be used for rotation to control the third and fourth generations of cotton bollworm. Early cotton-wool cockroach can be controlled by organophosphorus pesticides, and it can be used in rotation with butene fipronil at the later stage. Cotton aphid and spider mite were treated with acetamiprid and avermectin, respectively.
4The cotton was topping on July 15-20. After topping, 2% potassium sulfate solution was applied in combination with pest control. After finishing the group pointer on August 10, the invalid buds after September 5 were removed. Before and after October 5th. Spray ethephon for ripening.
The advantage of this planting mode is that it does not require too much investment compared to single cotton, and due to the large spacing between rows, the management of cotton is less labor-intensive, and there are fewer rotten bells, and the potential for increased yield is large. .
