Intercropping
Under the need to make full use of limited land for the development of high yields, stable production, and prolific production, intercropping and interplanting this traditional agricultural experience has increasingly attracted the attention of farmers. In many places, a variety of different modes of intercropping are used, some have achieved high yields, high yields, and high yields, while others have caused production losses and losses. The main reason for the loss is nothing less than a lack of understanding of the intercropping pattern and the lack of intervening methods.
1. Intercropping crops, plants should be able to match the height, so that it is conducive to air and light. Such as corn and soybean or mung bean intercropping.
2. Intercropping crops should be able to restrict each other's diseases and insect pests. If garlic is interplanted with corn, allicin secreted by garlic can disperse corn borers.
3. Intercropping crops, the root system should be different shades, in the soil to take each, to achieve the purpose of reducing consumption and increasing production. Such as wheat and legume green manure intercropping.
4. Round-leafed crops should be nested with sharp-leafed crops to avoid mutual light blocking. Such as corn and peanut intercropping.
5. The maturation time of the main and subsidiary crops intercropping should be staggered, so that late harvest crops can fully absorb nutrients and light energy in the late growth stage and promote high yields. At the same time, staggering the harvest period can avoid labor stress, but also conducive to intercropping crops. Such as sweet potatoes for intercropping.
6. Intercropping crops, the type of branches should be a vertical and horizontal, the formation of air and light composite group, to achieve the purpose of improving the benefits of photosynthesis. Such as corn and sweet potato intercropping.
7. Intercropping crops, the two sides of the species should benefit from each other. That is, it is conducive to the development and growth of the two sides, mutual benefit and symbiosis, or to the benefit of one side, but it does not harm the growth of the other side. For example, corn interplanting soybeans, rhizobia of soybeans can provide nitrogen fertilizer for corn, and nitrogen-free acids secreted by corn are preferred substrates of soybean rhizobia.
8. The shade-tolerant crops should be matched with drought-resistant crops so that they can fully exert the effects of water and fertilizers and enhance the resilience of crops. Such as corn, sorghum Intercropping sweet potatoes, corn, sorghum drought, sweet potato shade tolerance.
9. The flowering and sturdy crops on the stalks are intertwined with the crops that are solid in the ground. This will not result in fighting each other on pollination. The stalks on the ground that produce strong and solid crops can enjoy wind and insect media alone, which will help increase production.
10. Intercropping crops, planting density should be a narrow and narrow, so as to facilitate ventilation and ensure production advantages. Such as corn interplanting broad beans, broad bean lines, corn wide line.
11. Coiled crops and stalked crops can be used to save racks, save labor and money. Such as corn and cucumber intercropping, corn stalks can be used for cucumber strips, can reduce or inhibit cucumber mosaic disease.
12. Climbing vine crops should be intercropped with upright crops, such as between pumpkins for spring maize, wax gourd for corns between the nights, corns grow upwards, and pumpkins and melons grow horizontally, without affecting each other, and pumpkin nectar can lure the natural enemies of corn pods. Black eggs bee parasitic, can effectively reduce the damage of corn borer.
