How can fertilizing make grapes sweeter? Please introduce the method of fertilization in order to make the grape sweeter, you can refer to the following fertilization methods: first, pay attention to the base fertilizer around October, that is, the end of autumn is the best time for grape to apply base fertilizer. When applying base fertilizer, we should pay attention to the combined application of organic fertilizer and microbial fertilizer, apply mature organic fertilizer 4000 jin ~ 5000 jin per mu, Gymboree microbial fertilizer 2kg ~ 3kg; in addition, do not ignore the combination of chemical fertilizers (mainly nitrogen and phosphate fertilizer). Urea 1520kg or ammonium sulfate 30kg / mu. The base fertilizer should be dug deep into the ground combined with the soil. The fertilization method of organic fertilizer plus microbial fertilizer and chemical fertilizer not only provides quick-acting nutrition for grapes, but also improves the soil micro-ecological environment and plays a role in soil improvement. Reason: the beneficial microorganisms in Gymboree microbial fertilizer activate the soil through the secondary metabolites produced by their own life activities, increase the number of soil aggregates, enrich the soil, and increase the absorption rate of grape roots. prepare for the flowering and fruiting of grapes. Second, timely and reasonable topdressing 1. Topdressing before sprouting: in the early spring bud expansion period, it is better to use quick-acting nitrogen fertilizer, supplemented by microbial fertilizer, and root topdressing. The amount of fertilizer applied accounts for about 10% to 15% of the annual fertilizer application. This topdressing will promote the root absorption of grapes after entering the bleeding period. The application of Gymboree bacterial fertilizer can also increase the germination rate, increase the inflorescence, make the new shoots grow healthily, and thus increase the yield. If you apply enough base fertilizer in autumn, you can avoid topdressing at this stage. two。 Topdressing before flowering: spraying fertilizer outside the root two weeks before flowering, this time mainly by spraying boron fertilizer, but also by spraying Gymboree microbial sweetener. This sweetener can not only protect flowers and fruits, but also improve the transformation of photosynthetic substances, and has a good effect on flowering, pollination, fertilization, fruit setting and flower bud differentiation of grapes. It has a good effect on flower and fruit protection of fresh varieties such as Jufeng, Zui Jinxiang, Yuxuan 4, which are easy to drop flowers and fruits. 3. Topdressing in young fruit stage: after flowering, topdressing in young fruit expansion stage, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer. Combined with deep ploughing, the fertilizer is buried in shallow ditches or holes with a depth of 15 to 20 centimeters beyond 30 to 50 centimeters from the plant. In addition, spray Gymboree sweetener once. This topdressing can not only promote the expansion of young fruit, but also is very important to the flower bud differentiation of new shoots and secondary shoots. the spraying of sweetener can promote grape coloring and sugar accumulation in advance. 4. Topdressing during berry ripening: microbial sweetener was sprayed, and a large amount of Gymboree sweetener containing potassium and calcium was applied at the beginning of fruit coloring. Don't apply nitrogen fertilizer to the garden where there is plenty of fertilizer during this period. Root application and leaf spraying can be used as fertilization methods. Among them, Gymboree microbial sweetener plays an important role in improving berry sugar content, improving fruit quality and promoting shoot ripening; it can increase 0.8-1.5 sugar content, color ahead of time and prolong storage life. 3. in addition to reasonable base fertilizer and timely topdressing, some links of field operation can not be ignored. 1. Base fertilizer must be applied after ripening, especially chicken manure. It is best to use Gymboree fertilizer starter for ripening fermentation, and then apply it to the ground. Base fertilizer can not always be applied in one place, which can easily cause root system growth to be blocked and rot and die. two。 Try to avoid harming thick roots when topdressing, and be sure to irrigate once after fertilization. According to the fertilizer content of the soil in the garden, the lack of elements, especially some medium and trace elements, can be added. In addition, we must cooperate with reasonable pruning and weed removal in the field. Reasonable fertilization is the key to increase the yield and sweetness of glucose, in which the application of organic fertilizer and Gymboree microbial fertilizer increases the inhalable trace elements and a variety of organic acids secreted by microorganisms in the soil. these are the main factors to improve glucose accumulation and bright color.
