Cucumber cultivation techniques: how to top fertilize cucumber planting?

How to top fertilize cucumber planting? There are no netizens to introduce the method of cucumber planting in order to obtain high yield, it is necessary to top fertilizer according to the characteristics of cucumber fertilizer, the following introduces cucumber topdressing methods for your reference: method one, fertilization method before planting to melon: the soil temperature is still low in the early stage of cucumber growth (generally within a month after planting), if there is too much fertilization or watering, "rotten roots" will occur, which is due to the weak activity of the root system. Can not be fully absorbed, resulting in too much water in the soil, less air, suffocating and rotting the roots. On the other hand, the aboveground parts showed thin mesophyll, not bright leaf color and easy to wilt. Therefore, cucumber should not be fertilized and watered too much at one time, but the topdressing method of "applying thin fertilizer frequently and eating more with small amount" should be applied. Method 2. Fertilization method from young fruit stage to harvest period of cucumber: cucumber is a kind of vegetable with shallow root system and needs more fertilizer. In the process of production, topdressing should be increased from the young fruit stage to the harvest period of root melon to promote its growth and development and the demand for nutrients during the fruit expansion period. The top dressing of cucumber planted in greenhouse should not be planed or ditched, but must be applied in the ditch. Generally, the amount of topdressing should not be too much, with an average of 1.5 grams per plant. In the peak period of picking cucumber, every watering should be mixed with fertilizer and water, so that no fertilizer damage can be produced and high yield can be obtained. In the middle and later stages of cucumber growth, it was found that when the leaves were thin and yellow, 50 grams of urea was mixed with 15 kilograms of water, and then the leaves were fully stirred and dissolved, once every 5 days, for 5 times in a row. When it is found that there are many deformed melons or serious melons, use 50 grams of potassium dihydrogen phosphate to 15 kilograms of water, spray foliar, 3 Mel once every 5 days. In the later stage of production, the root is senescent and urea can be used at the same time. Method 3. Cucumber foliar topdressing method: cucumber absorbs not only nutrients from the soil from the roots, but also mineral nutrients from the leaves to promote fruit development. Generally, in the middle and later stage of production, it was found that nitrogen fertilizer was applied when the leaves were thin and yellow, and the leaves were sprayed after fully stirring and melting with 50 grams of urea and 15 kilograms of water, 3-5 times in a row every 5-7 days, and the effect was very good. When it is found that the melons are serious, the leaves are enlarged and there are many deformed melons, it can also get a certain effect when the water is stirred and melted with 50 grams of potassium dihydrogen phosphate and sprayed once every 5 days. In the later stage of production, when the root is senescent, urea and potassium dihydrogen phosphate can be used at the same time, each 50 grams to 15 kg of water, and then add half a bottle of Pushibao, stirring and melting, spraying leaves, which can replace root topdressing, increase cucumber disease resistance, delay senescence and strive for high yield. But in general, pesticides can not be arbitrarily added to chemical fertilizer and sprayed at the same time, easy to produce drug damage or drug failure, need to be sprayed at the same time, spray fertilizer in the morning and afternoon. Method 4. Matters needing attention in fertilization of cucumber: fertilization under wet soil is easy to cause differentiation of female flowers, deformed melons, resulting in physiological diseases such as fallen leaves, fallen flowers and chemical melons. Fertilization under the condition of high temperature will result in large water evaporation of plant leaves, which will affect the performance of fertilizer efficiency. In addition, it is appropriate to apply fertilizer in the early morning or evening. Click to get more cucumber cultivation techniques click to get more vegetable planting techniques
