In many places, intercropping of different models has been used invariably. In order to achieve better income increase effect, we will now elaborate on the model issues that should be noted for intercropping.
1. Intercropping can also be called three-dimensional agriculture, which is an agricultural production model that makes full use of planting space and resources. Generally, the intercropping of several crops at the same time is called intercropping. The symbiotic period of intercropping crops accounts for at least half of the whole growth period of a crop; the seeds sown at different stages are planted or transplanted between the rows of the pre-season crops at the later stage of growth. The method of planting the post-season crops is also called intercropping, and the symbiosis period of intercropping crops is relatively short, generally not more than half of the total growth period of intercropping crops.
2. Intercropping crops, plants should be able to match height, so that it is conducive to ventilation and light, so that the use of solar energy can be fully utilized. Such as corn and soybean or mung bean intercropping.
3. Crops intercropped and intercropped should have mutual restriction on pests and diseases. Such as garlic interplanting corn, garlic allicin can disperse corn borers, so that the incidence of corn sclerotia disease decreased.
4. Intercropping crops, the root system should be different shades. In other words, the deep-rooted crops and the light-rooted crops are used together with the hi-light crops. They can be used in the soil to make full use of the nutrients and water in the soil to promote the growth and development of crops and achieve the purpose of reducing consumption and increasing production. Such as the intercropping of wheat and legume green manure crops.
5, Intercropping, round-leaved crops should be nested with sharp-shaped crops, so as to avoid mutual shielding from light and improve the utilization of light energy. Such as the intercropping of corn and peanuts.
6. For crop intercropping, the maturation time of the main and subsidiary crops 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 tensions, and it is conducive to intercropping crops. For example, intercropping corns with sweet potatoes, the main crop corn is harvested first, and the sub crops sweet potatoes are harvested.
7. For intercropping crops, the type of branches and leaves should be vertical and horizontal. The interplanting between the lateral development and longitudinal development of plant-shaped branches and leaves can form a composite group with ventilation and light transmission, which can achieve the purpose of improving the benefits of photosynthesis. Such as the intercropping of corn and sweet potatoes.
8. For intercropping crops, the two species should have a mutual benefit. 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 the preferred substrate of soybean rhizobia.
9. For intercropping crops, the planting density should be narrow and wide. One kind of crop is wide and the other kind of crop is narrow, so it is easy to ventilate and guarantee the advantage of increasing production. Such as corn interplanting broad beans, broad bean lines, corn wide line.
10. Intercropping, intertwining crops and stalk-type crops when organic intercropping can save framework, save labor and money. Such as corn and cucumber intercropping, corn stalks can be used for cucumber racks, so that cucumber wrapped around corn stalks, but also reduce or inhibit cucumber mosaic disease.
