Fertilizer formula for soilless culture substrates of strawberries

Abstract

The invention discloses a fertilizer formula for soilless culture substrates of strawberries. 600-700 mg of calcium nitrate tetrahydrate, 100-200 mg of potassium nitrate, 20-50 mg of potassium chloride and 100-200 mg of ammonium nitrate are included in one kg of substrate; potash fertilizer is not used in the growing period, thereby reducing unnecessary fertilizer input on the one hand, and overcoming and preventing common diseases of strawberries in the traditional soil cultivation method on the other hand; a certain amount of dipotassium phosphate is added in the mature period to supplement the potash fertilizer, thereby facilitating fruiting of strawberries, shortening the mature time, enabling the strawberries to access to market in advance, improving the mouthfeel of mature strawberries, and improving the fruiting of single strawberry plant, as a result, remarkable economic and social benefits are realized.

Description

technical field [0001] The invention relates to the formula of crop fertilizer, in particular to a fertilizer formula of strawberry soilless cultivation substrate. Background technique [0002] Strawberry is a kind of fruit that is deeply loved by people. It has short cultivation period, early results and high market price. It has achieved rapid development in my country in recent years and has become an important economic crop for developing rural economy and increasing farmers' income in various places; traditional Problems such as high labor intensity, short fruiting period, and continuous cropping obstacles of the traditional soil cultivation method are becoming more and more prominent, which limit the further development of strawberry; , high-quality, convenient and good composite cultivation substrates are constantly being developed, synthesized and used. Composite substrate cultivation needs to be applied to various solid cultivation substrates. Solid substrate cultiva...

[0002] Strawberry is a kind of fruit that is deeply loved by people. It has short cultivation period, early results and high market price. It has achieved rapid development in my country in recent years and has become an important economic crop for developing rural economy and increasing farmers' income in various places; traditional Problems such as high labor intensity, short fruiting period, and continuous cropping obstacles have become increasingly prominent in the traditional soil cultivation method, which limits the further development of strawberry; , high-quality, convenient and good composite cultivation substrates are constantly being developed, synthesized and used

Composite substrate cultivation needs to be applied to various solid cultivation substrates. Solid substrate cultivation is referred to as substrate cultivation. Compared with hydroponics, the facilities are simple and the investment cost is low. Because the substrate has a certain buffering effect, the rhizosphere environment formed by the solid substrate Nutrients, water, pH and temperature change slowly, and the cultivation management is simple. There are many similarities with soil cultivation, and the cultivation techniques are easy to master. However, most of the strawberry seedling substrate fertilizer formulas in the soilless cultivation technology are simple available nitrogen and available phosphorus. Composed of three kinds of potassium and available potassium, there is a certain problem of uneven nutrition, the yield of strawberries is not high, and the taste is reduced, which greatly restricts the development of the soilless cultivation industry of strawberries
