When is the best time to fertilize peanuts and control excessive growth?
People today have very high demands when it comes to diet; they want to choose both healthy foods and foods that are very nutritious. The food I want to introduce to you today is called the peanut. Peanuts are also a food that everyone can eat often in everyday life. Many friends in rural areas also like to grow some peanuts at home, so when is the best time to fertilize peanuts?
When is the best time to fertilize peanuts
Before sowing, choose a yellow-brown soil plot with a deep plow layer, fertile soil, and convenient drainage and irrigation. After the autumn harvest, carry out deep plowing; after spring begins, carry out shallow plowing and repeated harrowing, that is, harrow deep and harrow thoroughly, harrow firm and harrow level, with level ground, broken soil, no clods, no hidden ridges, and no debris. Apply 2500kg-3000kg of high-quality organic fertilizer, 20kg-25kg of diammonium phosphate, 10kg of urea, and 12.5kg-15kg of potassium chloride per mu.
When is the best time to control excessive growth of peanuts
For film-mulched peanuts, from the pegging stage to the pod-setting stage, as the rainy season brings rainfall, that is, when high temperature and high humidity arrive, excessive growth is likely to occur. To control excessive growth, during the late pegging stage to the early pod-setting stage, or when the main stem height is 35cm-40cm, use about 20g of Zhuangbaoan per mu, mix with 40kg of water, and spray it on the leaves 1-2 times. This not only controls excessive growth, but also controls gibberellin biosynthesis in the peanut plant, reducing cell division and elongation, that is, inhibiting aboveground vegetative growth, making the plant shorter and the leaves thicker. It can also promote and improve root activity and improve the transport and distribution of photosynthetic products. Therefore, it regulates physiological and biochemical functions, increases dry matter accumulation, improves quality, and increases yield.
How to choose peanut planting land
1. Peanuts are a crop that flowers aboveground and sets fruit underground. The most suitable soil requirement is loose plow layer and deep plow layer sandy loam soil. However, yellow-brown loam soil is suitable for growing black peanuts. According to the Zhengyang soil survey, for yellow-brown soil plots yielding more than 500kg of pods per 1/15 hectare, the soil structure is a total soil thickness of more than 45cm, the weathered plow layer is about 30cm, and the pod-setting layer is a soft loam layer.
2. The soil texture is a clay layer below l0cm; 10cm-30cm is a silty clay layer. With such a soil structure, the capillary pores are small at the top and large at the bottom, while the non-capillary pores are large at the top and small at the bottom. The upper soil layer has good permeability, and the lower soil layer has strong water and fertilizer storage capacity and high heat capacity, so that water, fertilizer, air, and heat in the soil are coordinated and unified, which is beneficial to peanut growth and pod formation.
When are peanuts harvested
If peanuts are harvested improperly, harvesting too early means the pods are not full, the shells are tender, and the kernels are too shriveled, causing reduced yield; harvesting too late means the pegs and pods easily fall off, making harvest difficult and also causing reduced yield. When the leaves on the uppermost fruit branch of the peanut turn yellow, when the nighttime temperature is below 10°C, and when the pod shell network is clear and hard and the kernels are red and moist, then it can be harvested. Harvesting at this time means the peanut pods are plump, the pegs remain unbroken, and the pods do not easily fall off, ensuring high yield, a good harvest, and high efficiency.
In the article above, I also taught everyone some small tips for growing peanuts. Have you all learned them? In fact, peanuts are relatively easy to grow. They are also very convenient to care for, and the nutritional value of peanuts is also very high, so they are a food suitable for all ages.
