Peanuts are widely used and have good economic benefits. However, if you want good economic benefits, the quality and high yield of peanuts are very important. Do you know which factors will affect the high yield of peanuts? Huinong School has accumulated ten factors for everyone, let's take a look!
1. Severe roasting phenomenon is too late to plant, the temperature is too high when the seedlings are produced, and there is no timely seedling, it is easy to produce serious baking phenomenon, which leads to the hindrance of peanut plant development.
2. If the planting density is too large, the ridge surface is too small, and the plants are too close to each other, resulting in poor plant development. The main side branches are thin, the internodes are long, the plant growth is not strong, the fruit is promoted, and the middle fruit pod is small. And the amount is small.
3, neglect the characteristics of the cultivating peanuts with fruit needles into the soil, in the early flowering period, before the ridges, should be cultivated 2 to 3 times, and the soil and bones to protect the lyrics. Some agricultural products tend to ignore this link, resulting in difficulty in entering the soil and less pods.
4, too many branches and leaves are more fertile in some places, peanut plants are too busy, and no reasonable pruning, resulting in excessive branches and leaves, compete with the main branches to grab nutrients, and eventually appear more Production is reduced.
5, the correct method of no pruning embossing is to cover the flowering branches with moist soil after 3 to 5 days after the flowering of the peanuts, and to suppress the parts of only the long flowers, so as to promote the results of early needles.
6, the application of nitrogen fertilizer soil testing formula fertilization measures are not in place, the emphasis on the application of nitrogen fertilizer, resulting in stems and leaves long, stems are not weak, not only affect the multi-strong fruit, but also easy to fall.
7, the four ditch irrigation is not smooth side ditch, middle ditch, transverse ditch, ridge ditch supporting unreasonable, irrigation and drainage is not smooth, causing serious internal sputum phenomenon, making peanuts poorly developed, fruit Xiaoren 秕 easy rotten fruit.
8. The soil is too knotted. Before the peanut field, there was no timely winter ploughing and sunburn, resulting in increased weeds after the year, soil compaction, soil nutrient consumption, poor agglomerate structure, loose soil, and unfavorable fruit needles.
9. Spraying chemical agents improperly spraying chemical agents to prevent and cure diseases is a matter of course, but some sprays are too early, and the fruit needles have not been put into the soil in large quantities, seriously affecting the number of results, causing irrational growth and reproductive growth, and even appearing Rotten fruit, rotten straw phenomenon.
10. The micro-fertilizers such as ammonium molybdate, sodium bisulfite, boron fertilizer and potassium dihydrogen phosphate are essential for the growth of peanuts in the middle and late stages of growth. Increase production and income.
The above ten factors can affect the high yield of peanuts, so after reading it, we must avoid the above problems.
