Huangpi Rong Media News (all-media reporter Luo Ziwei Li Qiqi) is in the tea garden autumn and winter management of the critical period, on the 25th, the national tea industry technology system Edongnan Comprehensive Experimental Station to the Huangpi District system in the demonstration of the main body issued a batch of organic fertilizer, to help the green development of the tea industry in our region.
According to reports, nitrogen, phosphorus, potassium is the chemical elements necessary for the growth of tea, if the long-term application of chemical fertilizers, will lead to a decline in the automatic regulation ability of the soil, inhibit the activity of soil microorganisms. The organic fertilizer issued this time is produced by Hubei Tianshenjia Biotechnology Co., Ltd., which is an innovative enterprise integrating biological pollution control, three-dimensional breeding, organic fertilizer and bio-organic fertilizer, and polypeptide amino acid foliar fertilizer production technology.
Liu Zhifu, general manager of Hubei Tianshenjia Biotechnology Co., Ltd.: Our earthworm feces contain microbial bacteria, which are formed by the natural intestinal squeeze of earthworms to form tiny particles into the soil to form a stretch structure, which is most suitable for soil absorption. In recent years, earthworm manure because of its high plant nutrient content, rich microbial community and attention, the application of earthworm manure can not only alleviate a series of agricultural environmental problems caused by chemical fertilizers, but also in the plant soil diseases to play a biological control role, through which antagonistic microorganisms inhibit pathogenic bacteria, in biological control has important significance.
On the same day, Chen Xun and Li Changming, experts of the National Tea Industry Technology System Edongnan Comprehensive Experimental Station, walked into some tea gardens in Huangpi to inspect the growth of tea plants, understand the management of tea gardens in autumn and winter, and promote the technology of reducing the application of chemical fertilizers and pesticides and increasing efficiency. On-site guidance was also given on the current tea garden pruning, weed cleaning, and how to increase the application of organic fertilizer, guiding tea farmers to use organic fertilizer scientifically, further reducing chemical fertilizer input, and achieving the goals of cultivating soil, stabilizing yield and high yield, increasing yield and income.
The reporter learned that in recent years, there has been more use of machinery in the tea gardens in Huangpi, and the amount of chemical fertilizer applied by farmers when managing and protecting the tea gardens has been greatly reduced, and the pest prevention is not to carry the machine full of medicine in the garden, but to hang yellow plates in the tea garden. The amount of chemical fertilizers and pesticides is less, the efficiency is greatly improved, and this green production method is generally welcomed by tea farmers.
Chen Xun, an expert of the National Tea Industry Technology System and the Southeast Hubei Comprehensive Experimental Station: The management of tea gardens in autumn and winter is mainly fertilization, and we pay attention to scientific fertilization, mainly organic fertilizer. Especially now that the soil of many tea gardens is acidified, if organic fertilizer is applied, it can improve the flexibility of the soil and adjust its pH value.
It is reported that at present, the tea "three increases and three reductions" technology such as chemical fertilizer reduction, pesticide reduction, tea garden reduction and other tea "three increases and three reductions" are being promoted and used in tea gardens in the province, and initial results have been achieved, and a tea green production technology system of "product safety, cost saving and efficiency increase, environmental friendliness, processing transformation, and accurate service" has been basically built. The use of organic fertilizers and formula compound fertilizers instead of pure chemical fertilizers has greatly improved the organic matter in the soil of the tea garden, and the yield and quality have both improved.
