Recently, the author and Lei Yulian, general manager of Xiangyang Keliyuan Industry Co., Ltd. of Xiangfan City, Hubei Province, visited the villages of Dongjin and Daishan of Xiangyang District of Xiangfan City and some villages of concentrated cotton production in Banqiao Town of Yicheng City. With farmers, the growth and development of excellent cotton varieties such as Guoxin No. 8 were investigated. Dongjin and Laoshan were dominated by a single type of cotton, and Banqiao was dominated by intercropping cotton in cotton fields.
From the perspective of cotton seedlings, most of the cotton fields in Daejeon are 4 to 5 true leaves. The cotton seedlings of individual farmers have already seen buds. The development of cotton seedlings is slower than normal due to the influence of climate. However, the vast majority of farmers have relatively complete cotton seedlings, which lays a solid foundation for cotton production. When we asked about the plan for the next stage of fertilization, many farmers still had a long way to go in the application of potash fertilizer.
Ouyang, a cotton-growing farmer in the 3rd group of Dongwan Town, Dongjin Town, has 3 acres of new cotton varieties (lines) and has applied 35 pounds of compound fertilizer per acre as a base fertilizer. Currently there are 4.5 real leaves and seedlings. Also relatively strong, when asked how to manage the preparation of cotton buds, what fertilizer?
He said that he had pigeons in his house, 1,000 kilograms of pigeon droppings, and the droppings of pigeons on the line. He did not plan to use other fertilizers. When asked if he still applied potassium fertilizer? He said that pigeon droppings contain potash. In fact, the content of organic matter in pigeon manure and other poultry fertilizers is relatively high, but the effective content of potassium oxide is only 0.6% to 1.0%, which is obviously insufficient for cotton. Yicheng City Banqiao Town Shangwan Village Group 1 ancestral tree species have 9 acres of cotton fields, all intercropping with watermelon, he said, 80 kg of nitrogen and phosphorus potassium compound fertilizer has been placed under each acre, 100 kg of ammonium bicarbonate, did not intend to apply potassium fertilizer He also said that potassium in compound fertilizer is enough. In fact, although potassium fertilizer is contained in the compound fertilizer, the quantity is limited. Cotton and watermelon have already been used a lot in the early period, and there is not much leftover potassium fertilizer. The author found that cotton farmers still have a lot of misunderstandings about cotton potassium fertilizer.
The practice of cotton production in recent years shows that no matter what kind of insect-resistant hybrid cotton varieties, the demand for potash fertilizer is relatively large. Therefore, it is necessary to increase the understanding of potash fertilizer and give full play to the role of potash fertilizer in cotton production.
The effect of potash fertilizer is to increase the physiological activity of cotton and increase the utilization rate of nitrogen fertilizer; the second is to promote the growth of cotton roots, stems, leaves and reproductive organs, extend the functional period of leaves, and prevent premature aging; the third is to enhance disease resistance and resistance. In contrast, in the old cotton area can significantly enhance the ability of resistance to blight; Fourth, increase the rate of ringing, increase the weight of the single boll weight and the finger, according to the comparative test, the application of potassium fertilizer than the control, the single plant bell The number is increased by 2 to 3, the boll weight is increased by 0.6 to 1.4 grams, the child finger is increased by 0.25 to 1.3 grams, and the fifth is the increase of production by more than 10%.
The amount of potash used is generally 20-30 pounds per kilogram, and the insect-resistant hybrid cotton is about 60 pounds per kilogram of potash. In the early stage of application of compound fertilizer, the bud period needs to apply 30 kg of potash fertilizer per acre. Of course, all areas can be controlled by the soil, fertility, and climate.
The application of potash fertilizer for many years and more practices has proved that potash fertilizer is generally applied twice as well, once as the base fertilizer, and the second time as head fertilizer (Leaf Fertilizer). Flowering and boll-lining are also effective. When potassium is applied, mixing with organic fertilizers is promoted and the effect will be better.
