Liquid type special cucumber composite foliage fertilizer

Abstract

A liquid type special cucumber composite foliage fertilizer takes water as solvent and comprises macro, medium and micro nutrients and assistants. The content of the macro nutrient (N+P2O5+K2O) is larger than 70g / L, and the mass ratio is that N:P2O5:K2O equals to (4-6):1:(6-8); the content of the medium nutrient (Mg+S) is larger than 20g / L, and the mass ratio is that Mg:S equals to 1:(2.0-3.0); the content of the micro nutrient (Zn+Mn+B+Mo+Fe) is larger than 10g / L, and the mass ratio is that Zn:B:Fe:Mn:Mo equals to (4-5):(3-4):(2-3):(1-2):1; the chelating agent content is 5 to 35g / l, and the wetting agent content is 0.05 to 0.3g / L. When being used, the special cucumber composite foliage fertilizer is diluted with water with a ratio of 1:(500-800), and the dilution liquid for each mu is 100 to 150 kg and is sprayed at the middle and upper parts of the leaves, particularly the backs of leaves. The foliage fertilizer is sprayed before flowering of cucumber, once for each seven days and totally three times, and in the results period, twice spray is needed with a time interval of seven to ten days, and the average yield increase rate can reach above 15%.

Description

1. Technical field [0001] The invention relates to a chemical fertilizer, in particular to a multi-component compound fertilizer, to be exact, a liquid-type special compound foliar fertilizer for cucumbers. 2. Background technology [0002] Cucumber is a popular vegetable widely cultivated in my country. Cucumber fruit has a unique flavor, its nutritional value is very high, and it is rich in vitamins and minerals. It can be eaten raw, cooked or pickled. It is one of the main vegetables that the masses like to eat. However, cucumbers in many areas will have some physiological diseases during the growth process. If the expansion and elongation of the middle and top of the fruit are hindered, the fruit will be shorter and thinner than the normal fruit, and deformed fruits such as thick-tailed fruit, sharp-billed melon or pot-bellied melon will be formed. One of the main reasons is that the nutrient ratio is out of balance, which leads to the lack or excess of some nutrient el...

Problems solved by technology

However, there may be chemical reactions between macronutrients, medium nutrients and micronutrients, resulting in a reduction in the availability of nutrients. At the same time, the residence time of foliar fertilizers on the leaves of crops directly affects the utilization rate of nutrients.
