The latest course of fertilization techniques and methods for cucumbers

Cucumber is one of the common vegetables in our life, which is rich in a variety of vitamins, as well as the effect of clearing away heat and detoxification, in addition to its weight loss and beauty effect by female friends love. When planting cucumber, rational fertilization is the key to high yield, so how should cucumber be fertilized? Let's get to know each other along with Xiaobian.

1. Apply enough basal fertilizer

Cucumber yield is extremely high, so the fertility demand is large, so the application of sufficient base fertilizer is the key to planting cucumber, according to 5000 kg per mu calculation, need to absorb pure nitrogen 11.14 kg, pure phosphorus 7.66 kg, pure potassium 15.57 kg. The base fertilizer is mainly organic fertilizer, matched with appropriate chemical fertilizer. The fertilization method is to apply it once in combination with soil preparation. Generally, 4000-5000 kg of decomposed organic fertilizer is applied per mu, with 30 kg of urea and 30 kg of diammonium phosphate, and 20 kg of potassium chloride. If it is planted in spring and autumn, the amount of fertilizer can be reduced by about 10%-20% accordingly.

2. Fertilization of seedlings

The key period of seedling cultivation is also the basis for ensuring high yield of plants, so topdressing should be applied in time in order to promote seedling growth and health. Because in the seedling stage due to sufficient base fertilizer, so do not need to apply large fertilizer, generally in order to promote seedling growth, the use of organic fertilizer and chemical fertilizer matching method. Apply decomposed organic fertilizer or decomposed chicken manure 100-150 kg per mu, with appropriate amount of urea and calcium superphosphate, but avoid the phenomenon of burning seedlings, so in most cases, the fertilizer will be dissolved in water for irrigation, which can not only accelerate the fertilizer absorption rate, but also improve the fertilizer utilization rate.

3. Timely topdressing

After planting, plants enter peak growth season, when vegetative growth and fruiting occur together, and fertility is in great demand. Cucumber is a shallow root crop, and its fertility is weak, so it is necessary to fertilize several times at this time to ensure sufficient nutrients for plant growth and fruit development. According to research, if the yield of cucumber per mu reaches more than 5000 kg, 80-10 times of topdressing are needed before planting to harvest, and each time the fertilizer can be applied with 10-15 kg of diammonium acid per mu, or 250-300 kg of human excrement mixed with water.

4. Fertilization outside roots

Extra-root fertilization generally refers to foliar spraying, mainly to prevent plant deficiency caused by lack of certain trace elements, but also to avoid premature aging of plants. Foliar fertilizer is generally used in the peak period of fruit, when the temperature is low, the root activity is weak, the absorption capacity is poor, so in order to meet the normal fruit, you can supplement the required nutrients.
