Entering the "big summer" season, the growth and development of cotton is in a critical period, and the formation of quality and yield is also in this period. Under the thought of focusing on product quality, winning the market with product quality, and catering to customers, it is very important to pay attention to the quality of cotton.
In the eyes of ordinary people, the quality of cotton textile products and clothing mainly depends on the level of textile processing and manufacturing. In fact, the basic quality of cotton fiber products has a more important relationship with the implementation of the "pre-production, mid-production, and post-production" management measures in the cotton production process. The main technical indicators are: pre-production-select varieties suitable for local natural production conditions; in the production process-do a good job in field management during the cotton growth period, especially the boll period; post-production-do a good job in the quality differentiation of cotton purchases, and give Cotton price advantage improves rolling quality. When these three projects are realized, the natural and inherent quality characteristics of cotton will be reflected.
At present, the national cotton growth has entered "production", which is a period of vigorous development. Focusing on high-quality cotton production and management technology, three measures should be implemented:
First, according to the requirements of reasonable density, some weak seedlings, diseased seedlings, and pesticide-damaged seedlings should be removed from the field for treatment, so as to solve the contradiction of high density, uneven growth, healthy seedlings competing for water and fertilizer, and low benefits. The seedlings are cultivated into robust plant types, improving quality and increasing yield.
The second is to promptly follow up the management of topping, removing buds, and removing old leaves. Cotton grows vigorously in midsummer, but after a certain period of time, it is necessary to control the plant type, such as timely topping to control plant height, and manual removal of excess buds, empty branches and old leaves. And strive to improve the permeability of air and sunlight between the ridges and ridges in the row. The cotton boll grows from bottom to top. If the bottom of the cotton bolls is not well-lit, there is neither growth process nor external conditions for the formation of internal fiber quality, they will usually rot or fall off. As long as the early bells grow well, their inner qualities are good. Therefore, timely and effective removal of redundant buds, empty branches and old leaves is an important technical means for early quality cotton.
Third, combine the growth of cotton and carry out precise chemical control. The growth of cotton cannot be spread unrestricted, and the obese plant types are susceptible to insects and have poor resistance to wind and rain. Therefore, when the cotton grows to a certain shape, if the temperature is too high and the strength of the base fertilizer does not decrease, chemical regulation must be adopted to improve the quality resistance of the plant type by controlling the elongation growth and supplementing the leaves outside the roots. Recreate a breeding donor with high yield and high quality cotton fiber.
The implementation of the above technology will significantly improve the growth environment of cotton during the flowering and boll setting period, effectively solve the problems of early blooming cotton bud and boll shedding, high incidence, and low grade, increase the ratio of high-quality cotton to sales, and greatly increase the efficiency of cotton planting.
