What factors affect peanut planting density? Latest analysis
The peanut is one of China's main food crops. It not only has high nutritional value, but is also a very common oil crop in China. Its economic value is very high. Today, the peanut planting area is very large. When planting peanuts, we should pay attention to controlling the peanut planting density well. So what are the factors that affect peanut planting density? Below, the editor will briefly introduce them to everyone. Let's take a look together!
1. The range of rational close planting
When planting peanuts, you must pay attention to controlling the peanut planting density well. Rational close planting of peanuts can increase peanut yield, because in this way light can be used effectively. When planting is too sparse, because the total leaf area of the peanut plants is relatively small, photosynthetic capacity will also decrease as a result, leading to lower yield. In a suitable planting density, although increasing the density will lower the photosynthetic production rate, the amount of photosynthetic products will be lower than the increase in leaf area. Therefore, the plants' use of light energy is also relatively great, so peanut yield can be increased.
2. Soil fertility
Soil fertility has a very great effect on peanut growth. In an environment with sufficient soil fertility, the growth capacity of peanut plants is very strong, the root system is also relatively well developed, the plants are tall, and there are also relatively many branches. At this time, in order to prevent the plants from competing with each other for light, the planting density should be appropriately reduced. In cases where the soil layer is not deep and fertility is insufficient, peanut growth will be limited, the plants will be short, and there will also be relatively few branches. Therefore, at this time the planting density should be appropriately increased, following the principle of sparse planting in fertile land and dense planting in thin land.
3. Variety
Variety is also a main reason affecting peanut planting density. Different varieties differ relatively greatly in peanut plant morphology. So it will also affect peanut planting density, because the growth habits of each variety are different. Therefore, planting density should be controlled well according to the different varieties. For example, if it is a creeping-type growing variety, sparse planting should be mainly used, while upright-type varieties should be densely planted. If it is semi-creeping, then it should be determined according to the actual situation. Among these, the growth period and branching of the variety are all factors that should be taken into consideration in peanut planting density.
4. Climate
During peanut growth, its development will be affected by climatic conditions. When determining the density for planting peanuts, attention should be paid to adapting measures to local conditions. If planting in areas with higher temperatures and excessive [moisture], then peanut growth will be relatively vigorous, and at this time appropriate sparse planting should be used. On the contrary, if planting peanuts in arid areas with little rain, because of the lack of water, peanut growth will be hindered to a certain extent, and the planting density should be appropriately increased.
The above is a brief introduction to the factors affecting peanut planting density. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
