Vegetable fat loss remedy

The author recently learned from the vegetable farmer in Xiyang Village, Xiliu Village, Xiajin County, Shandong Province, that he had chased a cucumber for a few days ago. The name of the fertilizer was double ammonium bi-ammonium, 15~20 kg per mu , fertilizing point. The cucumber plant is 10-20 cm away. Now half of the cucumber plants in the field are wilting. What is going on?

After listening to his narrative, he inferred that his cucumber might be because the fertilization was too close to the roots and suffered damage. The following prevention measures are proposed:

Pouring a large water because Xiyang Village in Suliuzhuang Town is a sandy land, leaking water and leaking fertilizer, can quickly reduce the concentration of soil solution after pouring large water, it is easy to press the fertilizer down and alleviate the cucumber fertilizer.

Spray once to relieve the harmful effects of the pesticide on the cucumber surface of the phytotoxicity of 6000 times of love more than harvest or Yunda 120 , in order to enhance plant resistance and promote the plant to resume normal growth as soon as possible.

In addition, effective measures to prevent fertilizer damage include the following:

The organic fertilizer is applied to the organic fertilizer vegetable field, and the organic colloid is formed during the decomposition process, and the organic colloid has a strong adsorption capacity for the cation. When the chemical fertilizer is applied to the soil, the cation is mostly adsorbed by the colloid, so the soil solution is The relative amount is reduced, so that the concentration of the soil solution does not rise too high, which can increase the buffering capacity of soil nutrients and greatly reduce the possibility of fertilizer damage.

Fertilizer application in a fertile vegetable field must be applied in limited quantities and at the specified concentration, and the fertilizer damage will be greatly reduced. Generally , ammonium carbonate should not exceed 30 kg per acre , ammonium sulfate should not exceed 20 kg, and urea should not exceed 10 kg.

When fertilizing vegetable fields in uniform fertilization , it is necessary to adopt layered application and full-layer deep application method to achieve soil-fertilization fusion, so that the fertilizer is evenly distributed throughout the cultivation layer. At the same time pay attention to fertilization should be properly watered, keep the soil moist, reduce the concentration of the solution, and not cause fat damage.
