Flowers first prevent diseases and insect pests in summer
Due to the high temperature and humidity in summer, the resistance of plants decreases, coupled with some diseases and insect pests, it is easy to reproduce under high temperature, and the threat of diseases and insect pests is greater than that in other seasons. So, it's summer.

Six misunderstandings of foliar spraying of crops
Foliar fertilizer spraying, also known as extra-root topdressing, is a fertilization measure that can not be ignored in fruit tree production. This method saves labor, labor, quick effect and high utilization rate. It can absorb 80% of the amount of fertilizer spraying within 24 hours, apple, pear, Hawthorn and other fruit trees, spraying at flowering stage can increase fruit setting rate; spraying during leaf and fruit growth period can promote.

Extra-root nutrition and foliar fertilizer
Fertilizer is the "grain" of vegetables, 13 kinds of nutrients except carbon, hydrogen and oxygen are supplied by soil, and the application of base fertilizer is an important measure to replenish soil nutrition. At present, the types of fertilizers used in vegetables are generally divided into organic fertilizer (farm fertilizer), inorganic fertilizer (chemical fertilizer) and microbial fertilizer (biological bacterial fertilizer).

Foliar fertilization technique
Do not spray before hot weather or rain, so as not to burn seedlings or lose fertilizer. It is appropriate to spray every morning or afternoon, and spray again every 7-10 days. When spraying cereal crops or crops with smooth leaves, add 0.1% adhesive (such as washing powder, washing), etc. Otherwise, it works.

Foliar fertilizer spraying can not be "bathed" at will.
Foliar topdressing of vegetables is a method of dissolving fertilizer in water and spraying it on the leaf. this method has the advantages of simple, convenient, low cost, quick effect and high benefit. It is especially suitable for trace element topdressing, which plays a positive role in increasing the yield and quality of vegetables, but it should be scientific and reasonable. First, fertilizer species.

Foliar fertilization technique for vegetables
The aqueous solution of nutrients needed by plants is sprayed on the leaves to make the plants absorb effective nutrients directly through the leaves, which is called vegetable foliar fertilization technology. Compared with soil fertilization, this technique has the advantages of faster transformation, high fertilizer use efficiency and promoting the absorption of nutrients by roots. Foliar fertilizer can be roughly divided into big.

Key points of foliar spraying of micro-fertilizer on vegetables
Micro-fertilizer is an indispensable nutrient element in the growth and development of vegetables. spraying foliar fertilizer after diluting micro-fertilizer has the advantages of low cost, quick effect and high benefit. The main technical points are as follows: 1. Spraying concentration. Good results can only be achieved if the concentration is appropriate, especially if the concentration is not too high, otherwise it is not only useless, but harmful. ...

How to carry out foliar topdressing of fruit trees
First, the type, period and dosage of fertilizer spraying. Nitrogen fertilizer should generally be used in the early and later stages of fruit tree growth, properly combined with phosphorus and potassium fertilizer. Proper spraying concentration can effectively promote shoot growth, increase fruit yield and be beneficial to flower bud differentiation. Urea concentration 0.2% FLY 0.3% in the early stage and 0.3% FUX 0.5% in the later stage.

How to distinguish between true and false phosphate fertilizer
1. The role of phosphorus: expansion element (main nutrition for crop root, stem, leaf and fruit expansion), energy for cell division. Deficiency symptoms: The most direct manifestation is that the size of crops in the field is different, especially the orchard performance is the most obvious, and now most fields will also behave like this.

Excessive application of phosphate fertilizer does many harm
1. Due to soil application. There is a close relationship between soil conditions and the efficiency of phosphate fertilizer. In the soil with low content of organic matter and available phosphorus, the application of phosphate fertilizer to most crops can increase the yield. Therefore, phosphate fertilizer should be mainly distributed in the soil with low organic matter content and phosphorus deficiency in order to give full play to the fertilizer effect. Such as red soil dry field, yellow mud field,.
