Tomato humic acid water soluble fertilizer planting skills

Tomato planting knowledge

The following principles should be followed during planting:

1. According to the soil fertility conditions, comprehensive consideration of environmental nutrient supply, appropriate reduction of the amount of nitrogen and phosphorus fertilizer.

2, the old vegetable shed pay attention to the application of more compost with straw, less chicken manure, duck manure and other poultry manure, this can restore the ground force, supplement the carbon dioxide in the shed, it is also good for salt removal, reduce the obstacles of continuous cropping. The rich humic acid hydrolysate is converted from organic matter, which is rich in nutrients required by plants, and can improve soil compaction, acidification and other problems, including humic acid It can greatly improve crop yield and quality, and can improve crop resistance and make crops grow healthier.

3, the early spring temperature is low, the soil nutrient supply is slow, the early topdressing should keep up, after May, reduce the nitrogen fertilizer topdressing, increase the use of potassium fertilizer; the early autumn temperature is high, the soil organic nutrient supply capacity is strong, to control, do not topdress.

4. Recommended fertilization should be closely combined with reasonable irrigation. It is recommended to use sub-membrane furrow irrigation, drip irrigation, etc., each irrigation should not exceed 30 square meters per mu, and the sand should not exceed 22 square meters.

5, for the wintering long tomato, use summer leisure to plant sweet corn, to achieve a reasonable rotation, to overcome the obstacles of continuous cropping.
