Mastering fertilization management techniques to promote high yield of summer corn

Summer corn has a short growing time and is greatly affected by climatic factors. At this time, it has entered the summer rain season, and frequent stormy weather often occurs, which is particularly likely to cause corn lodging, affecting the growth and yield of corn. To achieve high quality and high yield of summer corn, in addition to selecting good varieties and timely planting, field fertilization management technology is also very important. Different fertilization methods are applied to different growth stages of corn, and then it can be supplemented with microbial fertilizer to achieve high quality and high yield. Effect.

1, seedling management. Focus on rooting and nurturing strong seedlings to lay the foundation for high yields. Maize seedling stage refers to the stage from emergence to jointing, rooting, differentiation of stems and leaves, and generally experience 20 to 25 days. During the three-leaf to five-leaf period of maize seedlings, timely thinning and seedling-setting can avoid crowding of seedlings, shading each other, and saving soil nutrients and water, which is conducive to cultivating strong seedlings. After Dingmiao, it is necessary to chase fertilizer in time, and full-fledged organic fertilizer, phosphate fertilizer, potash fertilizer, and golden treasure bacteria fertilizer are applied once. Among them, the golden treasure microbial fertilizer has the effect of accelerating the release of organic fertilizer and improving the efficiency of phosphate fertilizer and potash fertilizer. The golden treasure microbial fertilizer provides trace elements and stimulants for corn, stimulates the growth and development of the roots of maize, and has strong roots in corn seedlings. Strong seedlings play an irreplaceable role in the cultivation process.

2. Spike management. Focus on the rational management of fertilizer and water, regulate the contradiction between vegetative growth and reproductive growth, cultivate robust plants, achieve large panicles, and lay a good foundation for later high yield. From the jointing stage to the tasseling stage, corn usually takes 25 to 35 days, 45 to 55 days after emergence. This phase is the most vigorous growth stage in corn life. It requires large quantities of water and fertilizers, and has high growth efficiency. It is also the most important period for ear differentiation and is the best time for topdressing. At the heading stage, topdressing nitrogen fertilizers should be used as the main fertilizer, and Golden Baby microbial fertilizers should be supplemented. Microbial fertilizer has the advantages of increasing nitrogen use efficiency, fertility, improving soil structure, maintaining nutrient balance, reducing pollution, and enhancing the disease resistance and resistance of maize.

3, spend grain management. Pay attention to raising the roots and protecting the leaves, prevent premature decay, extend the filling time, increase the grouting strength, increase the number of grains, and increase the grain weight. Maize tasseling to maturity is a flowering period, which takes about 50 to 60 days. This period is mainly based on reproductive growth, which requires the application of grain fertilizer. Granular fertilizer is an important measure to prevent premature corn aging in the later period. During this period, the application of the microbial microbial fertilizer has significant effect of increasing production and income, and can increase corn production by more than 10%.

To improve the resistance of summer maize to heavy storm weather, and to achieve high quality and high yield of summer corn, it is necessary to manage fertilization in different growth stages of maize. Among them, in the different fertilization period supplemented by the application of Ginba microbiological fertilizer, it plays an irreplaceable role in the cultivation of strong seedlings and high quality and high yield of corn seedlings.

Organic Chaga Extract

Organic Chaga extract powder is made from perennial Chaga fruit bodies. Chaga is an irregularly shaped fungus that usually grows on birch, eucalyptus, and beech trees. The fruit body of Chaga is composed of oxalic acid, formic acid, acetic acid, polysaccharides, fiber, and resin, which can improve appetite and eliminate pain. It can reduce the cholesterol content in the blood. According to academic research, in the 16th and 17th centuries, Chaga was widely used in Eastern Europe, Russia, Poland, Finland and other folks to prevent and treat various incurable diseases such as various digestive organ cancer diseases (stomach cancer, esophagus) Cancer, bowel cancer, liver cancer), heart disease, leukemia, diabetes, etc., have shown excellent results. Clinical trials from Russia and Japan have confirmed that Chaga significantly improves the body`s immunity, inhibits the proliferation and metastasis of tumor cells, and can effectively prevent cancer in patients with gastric ulcers.
