Core tips
At present, many farmers are making full use of limited land and intercropping crops in order to obtain high-yield, stable-yielding, and prolific crops. Some have achieved high returns, while others have reduced production and suffered losses. Then, to obtain high returns from the land, it is necessary to understand what matters to note when planting intercropping.
1. Intercropping 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 the height, so that it is conducive to ventilation and light, so that the full use of solar energy. Such as corn and soybean or mung bean intercropping.
3. Intercropping crops can restrict each other's diseases and insect pests. 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 leaf-shaped 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 intercropping crops, 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. Intercropping crops, the type of branches should be a 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. Intercropping, shade-tolerant crops should be matched with drought-resistant crops, which can give full play to the role of water and fertilizer, enhance the ability of crops to fight disasters, and help reduce droughts and floods. Such as corn, sorghum intercropping sweet potatoes, corn, sorghum drought, sweet potato shade tolerance.
10. For intercropping crops, it is advisable to have a solid site between the ground and the underground. This is the combination of a flowering and sturdy crop on the stalk and a sturdy crop 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.
11. For interplanting 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 intercropping broad beans, broad beans, narrow rows of corn
12. Intercropping, intertwining crops and stalked crops when organic intercropping, can save frame, save labor and money. Such as corn and cucumber intercropping, corn stalks can be used for cucumber racks, so that cucumber wrapped around the corn stalk, but also reduce or inhibit cucumber mosaic disease.
13. Intercropping, vine-climbing crops should be nested with upright crops, such as pumpkins between spring corn, corn between the late corn gourd, corn grow up, pumpkin, gourd gourd, do not affect each other. And pumpkin nectar can induce the natural enemies of corn borer black egg bee parasitic, can effectively reduce the damage of corn borer.
14. Recognizing the relatives and phases of crops, and the relatives of crops, we mean that two or more crops are grown together. The chemical substances such as bacteriocins, auxins, organic acids and alkaloids secreted by both parties directly or indirectly affect each other. The growth of the two parties promotes normal growth for both parties, and vice versa. Blind crops include: corn and legumes, konjac and corn, sunflower and other high-stem crops, garlic, leeks and Chinese cabbage, cabbage and other cruciferous crops, soybeans and ramie, potatoes and kidney beans, onions and carrots. The relative crops are sunflowers, tomatoes, apples, pumpkins and potatoes, grapes and cypresses, sorghum and sesame seeds, walnuts and apples, grapes and peppercorns.
