Foliar fertilizer technology

In recent years, in order to increase the yield of crops, people have continuously increased the amount of chemical fertilizers applied to the soil. The resistance to soil application of chemical fertilizers will reach a certain amount and their benefits will decline, and the output will hardly increase significantly. Therefore, we must pay attention to foliar fertilizer. The application of foliar fertilizer is an effective way to increase crop yield and quality and is an important means of average fertilization.

1 Benefits of foliar fertilization

1.1 Foliar fertilization can quickly supplement the nutrients needed during crop reproduction, and it plays an important role in the recovery of certain crop deficiencies or the need to remediate natural disasters.

1.2 Foliar fertilization can enhance the body's metabolism, promote root absorption of nutrients, especially in the late growth period of crops, root ageing, weak absorption capacity, timely foliar fertilization, can prevent premature degeneration of crops and reduce yield.

1.3 Foliar fertilization is not affected by soil factors, and the fertilizer utilization rate is high. The efficiency is 6 to 20 times that of soil fertilization.

1.4 The amount of fertilizer is small and it is economical and efficient. Foliar fertilization is generally applied at a rate of 10% to 20% of the amount of soil fertilization, but its fertility is several times higher than soil fertilization, which can greatly reduce the investment of fertilizer.

1.5 Foliar fertilization can avoid groundwater pollution caused by the extensive application of fertilizer in the soil.

2 foliar dressing

Fuer 655 is composed of plant growth regulators, macronutrients, various trace elements, and humic acids. It has a rapid effect, a low cost, and a significant effect. Suitable for a variety of crops, spray 400 ~ 600 times 2 or 3 times, can increase production by 10% to 20%.

3 Technical points

3.1 The amount of liquid sprayed by foliar spray is preferably wet and not drip.

3.2 The cloudy evening or the evening after sunset is the best time for spraying.

3.3 Use period: Soybean initial flowering stage, scab stage, and granule stage are applied once. Corn sprayed once at the seedling stage and jointing stage. Wheat is sprayed once during the booting period and the initial flowering period. Rice seedlings, young panicle differentiation period, booting period were sprayed once.
