Three questions for preparing fertilizer in spring
How much fertilizer to prepare Fertilizer application amount can refer to the amount of fertilizer used in previous years. If high yield or planting area is expanded, the amount of fertilizer can be appropriately increased. Here is a simple estimation method. Take field crops as an example, the current total nitrogen application rate (N) of a crop with high yield levels is 8-15 kg/mu, and the yield of high-yield corn, wheat, and rice with a yield of 500 kg per mu is generally not less than 12 kg (Northeast Black Soil Such fertile soil can be further reduced). About half of nitrogen is used as basal fertilizer, and the other half is used as top dressing, once or in divided doses. The amount of P fertilizer (P2O5) is generally not more than half of the amount of nitrogen applied except for winter wheat and rapeseed; the amount of K fertilizer applied (K2O) Between the amount of nitrogen applied and the amount of phosphorus applied, the north soil tends to use phosphorus, and the southern soil tends to use nitrogen. These are the amount of nutrients, divided by the nutrient content identified on the fertilizer bag, to obtain the specific fertilizer application amount. How to choose the quality of variety identification When we investigated the agricultural production and the fertilizer market, we found that many farmers’ friends pay more attention to the true and false fertilizer prices and price when purchasing chemical fertilizers. They rarely pay attention to whether the compound fertilizer ratio is suitable for their own soil and crop characteristics. Basal fertilizers should generally use ternary compound fertilizer whose ratio of nitrogen and phosphorus is roughly 1:1. If it is a one-time fertilizer, high nitrogen compound fertilizer should be used, and the amount of fertilizer should be increased appropriately. When buying compound fertilizers and all kinds of so-called new fertilizers, we must look at the three “certificatesâ€, namely, product registration certificates, production licenses, and product quality standards. Since individual farmers do not have the conditions to check the quality of fertilizers or whether they contain harmful substances, they should go to trusted merchants to purchase well-known brands, and they must keep a good record of purchasing fertilizer. How to store fertilizer The basic requirements for reasonable storage are to prevent the loss of nutrients from fertilizers, reduce the agglomeration of fertilizers, prevent poisoning of humans and animals, and fires. Do not stack ammonium nitrogen fertilizers with seeds and microbial fertilizers to prevent volatile ammonia from damaging seeds and active microorganisms. Especially for planting specialized households, if the amount of fertilizer purchased is large, the fertilizer can be stored in a warehouse sheltered from rain and ventilation, or temporarily deposited in a place with high dryness, no accumulation of water, and fireproof conditions. Place reeds or plastic sheets on the floor before stacking, and then cover with plastic sheets to prevent rain and snow from getting wet.
"All medicines have their own environment", Zhongning's unique natural conditions have created "the unique quality of Zhongning goji"
First. Soil: Zhongning is located in the central part of Ningxia Hui Autonomous Region, surrounded by mountains. The Yellow River and Qingshui River flow through the county. Large areas of alluvial plains are formed on both sides of the Yellow River. The land is deep and fertile, rich in more than 30 kinds of trace elements required by goji. The main root of goji is more than 3 meters deep, and the lateral roots are criss-crossed, with strong sprouting power and soil penetration. Therefore, Zhongning's unique and fertile soil provides sufficient organic nutrients for the growth and development of goji.
Second, water quality: Qingshui River, the largest tributary of the Yellow River that flows through Zhongning County, flows into the Yellow River in Zhongning County. It is a typical arid and semi-arid river with extremely high salinity, and more bitter goes more downstream. It is precisely because of the unique water quality of Qingshui River that creates the unique quality of the soil here.
Third, climate: Zhongning County is located in the transition zone between the Inner Mongolia Plateau and the Loess Plateau, and belongs to the northern temperate continental monsoon climate zone. Surrounded by mountains, with sufficient sunlight, drought and little rain, strong evaporation, effective accumulated temperature of 3363℃, high accumulated temperature, good heat conditions, which is conducive to the growth of goji, the annual sunshine time is as long as 2970h, which is significantly higher than the 2600 hours required for the growth of high-quality goji.
These unique natural conditions make Zhongning goji enjoy the reputation of "the best in the world".
