Peanut timely harvesting and seeding skills
Grasping the harvest time of peanuts is very important for improving the yield and quality of peanuts. While harvesting peanuts, it is important to pay attention to keeping good seeds in order to ensure the high yield of peanuts in the coming year. The suitable harvesting time and seedling techniques for peanuts are described below for reference by farmers. First, timely harvest. Since peanuts are crops that bloom on the ground and the ground produces continuous cropping, the maturity of the pods is inconsistent. It is generally difficult to see from the outside whether the pods have reached full maturity or not. Harvesting too early or late will affect their yield and quality. Therefore, to determine the appropriate harvest period of peanut is particularly important, generally from the following three aspects to determine whether the peanuts have reached the harvest period: A look at the growth period. The growth period of common peanut varieties is about 125 days. Second look at the temperature. When the average day-night temperature is below 12°C, the plants basically stop growing and can be harvested at this time. Three to see plants. Under normal circumstances, when peanuts enter the final stage, most of the nutrients in the plants have been transported into the pods. The plants show an aging state. The tops stop growing, the upper leaves turn yellow, and the base and middle leaves fall off. Most of the time The fruit is full and can be harvested. Second, leave seeding skills. Special attention should be paid to the selection of seeds to be retained. Seeds with the characteristics of the variety, neat branching, and concentrated results should be selected as seeds. Plants with the following symptoms cannot be used as seeds: 1. Greedy late-maturing plants. This kind of plant has poor development in the early stage and overgrowth in the later stage. It not only results in a later result, but also results in less fruit and poor fruit plumpness. 2. Prematurely weak plants. Peanut pods have not yet matured, but the plants on the ground are prematurely senescent. Accumulation of organic matter in kernels is not sufficient. Not only the germination rate is low, but also the characteristics of the cultivar will be lost, which will directly affect the yield. 3. Diseased plants. The pods of plants with blight, leaf spot, and rust, when used as seeds, not only spread the disease, but also produce weak seedlings. China Agricultural Network Editor
