Factors affecting Peanut planting density

Peanut is one of the main food crops in China, which not only has high nutritional value, but also is a very common oil crop in China. The economic value is very high. Now the planting area of peanuts is very large, when planting peanuts, we should pay attention to control the planting density of peanuts. So what are the factors that affect peanut planting density? The following editor will give you a brief introduction, let's have a look!

1. The scope of reasonable close planting

When planting peanuts, we must pay attention to control the planting density of peanuts. Reasonable close planting of peanuts can increase the yield of peanuts, because it can make effective use of light. When planting is too sparse, because the total leaf area of peanut plant is relatively small, so the photosynthetic capacity will decrease, resulting in a decrease in yield. In the suitable planting density, although the increase of density will reduce the photosynthetic productivity, but the number of photosynthates will be lower than the increase of leaf area. Therefore, the light energy utilization of the plant is also relatively large, so it can increase the yield of peanut.

2. Soil fertility

Soil fertility has a great effect on the growth of peanut. Under the environment of sufficient soil fertility, the growth ability of peanut plant is very strong, the root is also more developed, the plant is as high as, and there will be more branches. At this time, in order to prevent plants from grabbing each other for light, it is necessary to appropriately reduce the planting density. When the soil layer is not deep and the fertility is insufficient, the growth of peanut will be limited, the plant is short and the branches are less. Therefore, at this time, it is necessary to appropriately expand the planting density, based on the principle of sparse planting in fertile land and dense planting in thin land.

3. Variety

Variety is also the main reason that affects the planting density of peanut, and the use of variety has a great difference in the morphology of peanut plant. So it will also affect the planting density of peanuts, because the growth habits of each variety are different. Therefore, the planting density should be controlled according to different varieties. For example, if the varieties growing in the creeping type should be sparsely planted, while the varieties in the erect type should be closely planted. If it is semi-creeping, then it depends on the actual situation. Among them, the growth period and branches of varieties should be taken into account in peanut planting density.

4. Climate

During the growth of peanut, its development will be affected by climatic conditions. When planting peanuts to determine the density, we should pay attention to measures in accordance with local conditions. If it is planted in areas where the temperature is relatively high and surplus, then the growth of peanuts will be more exuberant, so it is necessary to plant sparsely at this time. On the contrary, if peanuts are planted in dry and rainy areas, the growth of peanuts will be hindered to a certain extent because of lack of water, so it is necessary to appropriately expand the planting density.

The above is a brief introduction of the factors affecting peanut planting density. That's all for today's introduction. This article is for reference only. I hope it can help you all.
