Soil organic matter is the source of carbon nutrition for peanuts, and the carbon dioxide absorbed in photosynthesis mainly comes from the atmosphere, and the carbon dioxide generated by decomposition of soil organic matter is the main and important source of carbon dioxide supplement for soil. If there are two different crops in a border, it will have an impact on mechanized harvesting.
besides, the price of corn is not too high in recent years. The effect of planting corn on peanut yield has reduced the income of farming. The price of peanuts has been relatively stable in recent years. Now the planting and harvesting of peanuts have also been mechanized.
The elements needed for peanut growth, such as sulfur, phosphorus, potassium and so on, are mainly completed under the action of microorganisms. Or peanuts are not sold as the main food, so they are planted and eaten by themselves, without thinking so much, which has no effect on corn at all. It is said that corn interplanting is the best crop, or sweet potato, mushroom, potato, cabbage and radish, which do not affect each other's growth and income, but at the same time, peanut ridging should be separated from corn by a certain distance. Secondly, it can prevent corn flower powder from falling vertically on peanut leaves, but affect the color light and heterosexual damage of peanut leaves. Secondly, we should consider the color of peanuts, and plant peanuts before planting corn. Don't mix corn fertilization with peanut fertilization.
The wheat stubble should be cleaned in advance and ferrous sulfate should be applied to control the pests under the roots. If some corn is dense and thick, peanuts will have less hair heads, long straight lines, fine leaf spots or mosaic disease due to poor permeability. In this regard, organic manure should be applied in advance to make up for the lack of soil fertility or foliar fertilization. The function of absorption and utilization for field crops. The interplanting of two crops can make use of each other, learn from each other's strengths and improve yield. Moreover, peanut intercropping with corn has good ventilation, which can make full use of light energy and increase corn yield. It is a measure to make full use of marginal effect and light to obtain high yield.
the planting density will also be different, such as: 4 rows of peanuts +2 rows of corn, 6 rows of peanuts +2 rows of corn, 8 rows of peanuts +2 rows of corn, 11 rows of peanuts +2 rows of corn, etc., and choose the appropriate planting method according to the local specific conditions. For example, the helper asked a friend in Hebei that he was afraid that the corn would be too fat-sucking to grab peanut fat when it grew up, and generally only planted corn on the edge of peanut ridge, with peanuts in the middle. In this way, corn can also be interplanted with sorghum or sweet potato, but it is best to eat the leaf variety sweet potato, so that the sweet potato will not be affected by the fat absorption of corn.
generally, there are two rows of corn intercropping with two or three rows of peanuts, or four rows of peanuts intercropping with three rows of corn and two rows of peanuts and six rows of corn, which can not only give full play to the advantages of corn, but also help to increase the light and yield of peanuts.
