A、The application of compound fertilizer

Compound fertilizer to join the fertilizer utilization rate is low, volatile fast, large losses. Compound fertilizer, especially ammonium bicarbonate, volatility is very strong, does not advocate large area spreading. While compound fertilizer, ammonium sulfate, potassium sulfate can be manipulated inconvenience, vegetables in the process of spreading compound fertilizer, especially when spreading a large area do not spill on the leaves of vegetables, so as not to burn.

B、The application method of compound fertilizer

Water fertilizer sprinkled in the ditch, so that the water melted into the soil and fertilizer.

Fertilizer application method: on the one hand, there will be partial loss of volatilization. On the other hand, there will be a part of deep water penetration into the soil, which cannot reach the root vegetables, so it cannot be absorbed. The advantages are simple operation and less labor. If there is a serious lack of fertilizer for a large area of vegetables, you can use compound fertilizer as the preferred fertilizer. At present, the more used compound fertilizer in the market is produced by Nagric. The best chemical fertilizers are blended with water before melting. Bad fertilizers and fertilizer residues are easily lost in the channels. In the field, the crop roots are deep and there is also a waste of fertilizer penetration.

C、The characteristics of drip irrigation fertilization

Drip irrigation fertilization is characterized by one or several nutrients required by plants after fertilizer filtration, through the drip irrigation system, with drip irrigation water-soluble fertilizer automatically into the soil around the roots of vegetables. At present, the water-soluble fertilizer that is more used in the market is also produced by Nagric. Covering film, used as compound fertilizer to join the fertilizer non-volatile, almost no loss. Save water, save labor. Fertilizer application according to the main components and characteristics of fertilizer application, is a more advanced fertilizer application method. The disadvantage is the need to install supporting drip irrigation and water supply equipment, and strict control of the mulch film, and the level of soil nutrient determination, the investment is relatively high.

D、How to bury fertilizer with compound fertilizer

compound fertilizer

Buried fertilizer includes vegetables planted before the deep substrate is buried in the soil and fertilizer. This planting process, generally using slots, holes, strips. Organic fertilizer and chemical fertilizer are then raked to the whole fine, this method is less expensive, but labor intensive and inconvenient to operate. Using plants and tree roots buried. Because the fertilizer concentration is high and the depth is close to the root system, it is easy to damage. Therefore, when burying fertilizer, trenching and digging holes need to be more than 10 cm from the foundation. Vegetables in the early stage of growth generally do not apply compound fertilizer. But in the actual growth process, vegetables in the peak of growth is the need to spread fertilizer. Therefore, the buried fertilizer method is suitable for use in high temperature conditions to prevent negative effects. After watering, buried low concentration of soil fertilizer.

E、How to use compound fertilizer foliar fertilization

Vegetable production management process, in addition to pay attention to timely supplementation of nutrition. Likewise, you can also combine with the spraying of pest and disease drugs, to make multiple foliar fertilization. This method is not only fast, but also low in dosage. This is an economical and effective method of fertilization. The effect is more obvious when fertilizer application takes place when the plants become senescent and the root system has insufficient or severely insufficient absorption capacity.

Foliar compound fertilizers use chemical fertilizer compound fertilizer supply, potassium phosphate and compound fertilizer, in addition to the usual chemical fertilizers and other factors, many manufacturers have also developed micronutrient fertilizers and amino acid fertilizers suitable for foliar spraying. For example, drought resistance, plant protection factors and so on. These are all effective to a certain extent. If, for example, the nutrients needed for vegetable growth come mainly from soil application. Then, foliar fertilization can only work as an auxiliary measure.

F、How to use compound fertilizer for nutrient fertilization

Nutrient fertilization refers to the mixing solution of nutrient compounds dissolved in water for different types of vegetable crops at different stages of fertilization requirements under soilless conditions. It provides the necessary nutrients for crop growth without waste and water loss. Compared with soil cultivation, the water saving effect is very obvious. In addition, modern equipment manages the process, which saves a lot of labor. The difficulty lies in the preparation of the nutrient solution, which must combine all the nutrients required for the growth and development of a particular vegetable crop. Since the main source of fertilizer belongs to chemical fertilizers, it is necessary to make precise calculations and to combine them in a reasonable way. Comprehensive adjustment of the ph value of the nutrient solution and the total salt content, to maintain a chemically balanced nutritional solution.

G、Eggplant using compound fertilizer tips

compound fertilizer

Through the above instructions, we should have an understanding of how to apply compound fertilizer in the process of growing vegetables. The following we will take planting eggplant as an example, to introduce its compound fertilizer application skills.

1、Basic fertilizer

Eggplant fall and winter crops plant in mid to late August. Overwinter crop plants in late October to early November. Winter and spring crops plant in December. When planting, apply organic fertilizer in combination with plowing and tilling, spread compound fertilizer 45% content 80-100 kg per mu, or 40% content 100-120 kg per mu.

2、Chase fertilizer

When the eggplant grows to egg size, start to chase fertilizer with high nitrogen fertilizer, and 15-25 kg per mu at a time. After entering the fruiting stage, combined with watering, chase compound fertilizers once every 20 days or so. Each time 25-30 kg per mu. During the fruiting period, it is necessary to apply less phosphorus fertilizer to avoid affecting the fruit quality.
