  30 methods and benefits of intercropping

 

1. Cotton + corn: Corn in the cotton field can trap eggs to reduce the damage of cotton seedlings. In the cotton field, every 10 meters of corn is planted with 1 row of corn (50 to 60 piers per acre, 2 to 3 per pier), which can effectively improve the cotton field ecological structure, trap cotton bollworm and corn cocoon to lay eggs, thereby reducing cotton seedlings. The amount of eggs dropped. In the cotton field of intercropped corn, the amount of eggs on the cotton seedlings decreased by an average of 60% to 70%.

 

2, cotton (or rape) + garlic: cotton or rapeseed between the garlic can repel pests to reduce eggs. Garlicin, which is volatilized from garlic, has a spicy odor, which can make the locusts that damage cotton or rapeseed “back away”, and the occurrence of second-generation cotton bollworm on cotton is also significantly reduced, and Other pests will “smoke the wind and escape”. According to the survey, no seedlings were used to control the nursery, cotton seedlings were not rolled, and the same conditions of single cropping were used to control the nursery twice, and the highest coiling rate was still 25%-28%; the second generation of cotton bollworms was planted. The strain has only 12 eggs, and the number of eggs in a single crop is more than 500.

 

3, cotton + wheat: wheat cotton intercropping, this method of planting is very beneficial to control cotton aphids. Because of the barrier function of wheat, wheat cotton has not only directly affected the migration of cotton aphid, but also the temperature of cotton field is about 1 °C lower than that of single field. Together with the effect of natural enemies of wheat, the nursery can be controlled without the application of pesticide control.

 

4, cotton + mung bean: cotton mung bean intercropping, May and June, single cropping cotton is small, not conducive to natural enemies hidden, inhabited; intercropped green mung bean hair fast, field microclimate is conducive to the survival and reproduction of natural enemies, and soybean meal is a natural enemy Good food, so the amount of natural enemies increases, cotton pests are alleviated, generally less than 1-2 times.

 

5, cotton + sorghum: cotton sorghum planted a small amount of sorghum next to the cotton sulcus, can trap spiders, scorpion bees, scorpion flies, ladybugs, small flowers and other natural enemies to inhibit the occurrence of cotton mites, cotton bollworm and other pests And harm.

 

6, corn + cucumber: corn intercropping cucumber can reduce the occurrence of cucumber virus disease. Planting cucumbers in corn rows can reduce cucumber mosaic disease by 61.6%. It can also use corn stalks to make cucumber racks, saving money and labor.

 

7, corn + sweet potato: The two branches of the crop are longitudinal growth and one is lateral growth, which is conducive to ventilation and light transmission, and enhance photosynthesis.

 

8, corn + pumpkin (or peanuts): corn or peanuts can effectively reduce corn damage. Pumpkin nectar can induce the parasitic natural enemies of the corn borer, the black bee, which can effectively alleviate the damage caused by the black bee. In addition, corn intercropping peanuts can also significantly reduce the damage of corn mash. Corn pointed leaves, peanut round leaves, together planting will not block each other, providing light energy utilization.

 

9, corn + spicy (green) pepper: corn and spicy (green) pepper intercropping can reduce the spicy (green) pepper disease. Due to the shading effect of corn, the sunburn and viral diseases of peppers are reduced by 72% compared with single cropping; the intercropping of corn and green pepper can reduce the green pepper virus disease by 56.9%.

 

10, corn + cabbage: corn intercropping cabbage can reduce a variety of diseases of cabbage. Maize intercropped cabbage field, because the field temperature is reduced by 0.5 °C compared with the single field, and the ground temperature is lowered by 2 °C, the cabbage virus disease can be reduced by more than 20%, the white spot disease is reduced by 18%, and the occurrence of cabbage soft rot and downy mildew is also significantly reduced. .

 

11, corn + peas: corn and pea mixed can achieve double harvest. Both corn and peas will benefit each other and both will increase production.

 

12. Corn + Soy: Soybean rhizobium can fix nitrogen and provide nitrogen fertilizer for corn. The substances secreted by corn can also promote the growth of rhizobium.

 

13, corn + broad bean: corn planting density is wide, broad bean is narrow, intercropping planting is easy to ventilate.

 

14, wheat + tobacco: wheat smoke intercropping, because wheat plants can hinder the migration of soot, and the role of natural enemies such as the seven-spotted ladybug in the wheat field, can effectively control the damage of the haze. According to the report of the Special Crops Research Institute of Shaanxi Academy of Agricultural and Forestry Sciences, tobacco mosaic disease occurred in single crop field, with a disease rate of 62.7% and only 5% for cropping.

 

15. Wheat + broad bean: Wheat intercropped broad bean can change the microclimate in the field, and the plants are well ventilated and light-transparent, especially reducing the occurrence and spread of broad bean brown spot disease and wheat rust, which can alleviate droughts and floods.

 

16. Garlic + corn: The pungent odor of garlic can inhibit the occurrence of insects such as corn borer and mites.

 

17. Garlic + rape: The principle is the same as above, which can reduce the harm of rapeseed. Garlic intercropping with other crops can also reduce the occurrence of pests.

 

18, potato + garlic: potato and garlic intercropping can inhibit the occurrence of potato late blight.

 

19. Soy (or peanuts) + ramie: ramie between soybeans or peanuts can kill pests and reduce insects. Castor can secrete special substances and reduce the damage of chafers to crops. In the soybean or peanut field, the ramie is evenly distributed on the ground, so that the golden tortoise shells that lay eggs in the bean fields and peanut fields can be poisoned and killed after eating the nettle leaves, which is no less effective than chemical pesticides.

 

20, flax + spring wheat: mixed with flax and spring wheat can significantly reduce the occurrence of cotton bollworm. The flax and spring wheat are mixed into the field, and the amount of cotton bollworm is significantly reduced due to the protective effect of the wheat. According to the investigation of the Changji County Agricultural Research Institute in Xinjiang, the cotton bollworm in the mixed field has only occurred in a small amount on the ground, while the average single-grained field has 4-10 heads of cotton bollworm per square meter, and the flower buds are as high as 35%.

 

21. Eggplant + Cabbage: When the cabbage grows to about 8 cm, the planting of eggplant can reduce the harm of the tiger to the eggplant.

 

22, leeks + cowpea: leeks absorb part of the nutrition, so that cowpeas will not grow long and more pods. Cowpea also shades the leek and promotes the growth of the leek.

 

23, green beans + shallots: shallow roots and deep roots, rational use of soil space, make full use of soil nutrients.

 

24, 芋艿 + melon: different growth cycle, staggered harvest time, easy to harvest. It also facilitates the rapid absorption of nutrients and promotes high yields.

 

25, grape + cucumber: the incidence of grape downy mildew and brown spot disease will be reduced.

 

26, Chinese cabbage + small cabbage heart: Chinese cabbage plants are larger, the gap between the plants is large, and the intercropping can make rational use of the land.

 

27, ginger + watermelon: ginger Xiyin, watermelon Xiyang, with planting can reduce the risk of high temperature on ginger.

 

28, melon + tomato: the tomato side of the nest melon, can prevent the occurrence of tomato disease.

 

29, onion + carrot: round onion and carrot intercropping can drive each other pests. The scent of the onions and carrots can expel each other's pests.

 

30. Cruciferous vegetables + lettuce (tomato or mint): Lettuce, tomato or mint between cruciferous vegetables can evade cabbage. The pungent odor of lettuce, tomato or mint can make the cabbages that lay eggs on cruciferous vegetables such as cabbage and cabbage escaping.

 

  There are many ways to intercropping intercropping, planting friends can give one to the other, rational intercropping, reduce disease, increase production!
