Nutrient solution for substrate culture of cucumbers

Abstract

The invention relates to a nutrient solution for substrate culture of cucumbers. The nutrient solution is composed of 12 kinds of organic raw material such as tetrahydrate calcium nitrate, potassium nitrate, potassium dihydrogen phosphate, magnesium sulfate heptahydrate, ammonium sulfate, potassium sulfate, chelated iron, manganese sulfate monohydrate, zinc sulfate heptahydrate, borax, copper sulfate pentahydrate, sodium molybdate. The nutrient solution for substrate culture of cucumbers has following beneficial effects: the nutrient solution is high in operability when being utilized for soilless substrate culture of cucumbers and helps increase the yield of quality cucumbers.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a nutrient solution for cucumber substrate cultivation. Background technique [0002] Cucumber (scientific name: Cucumis sativus L.var. sativus) is a plant of the genus Cucumber in the family Cucurbitaceae. Annual vines or climbing herbs; stems and branches elongate, with ribs, covered with white rough hairs. Tendrils thin. The petiole is slightly rough, with rough bristles; the blade is broadly ovate, heart-shaped, membranous, and the lobes are triangular and toothed. Monoecious. Male flowers: constant clusters in leaf axils; pedicel slender, puberulent; corolla yellow-white, corolla lobes oblong-lanceolate. Female flowers: solitary or sparsely clustered; pedicel stout, pilose; ovary scabrous. The fruit is oblong or cylindrical, yellow-green when ripe, with a rough surface. Seeds are small, narrowly ovoid, white, without margins, and both ends are nearly acute...

Problems solved by technology

[0003] Cucumbers are grown by traditional soil cultivation techniques. Due to the continuous cropping cultivation all year round, the soil is seriously hindered by continuous cropping and a large amount of soil nutrients are lost. Excessive application of chemical fertilizers leads to soil compaction, acidification, and serious soil diseases and insect pests. Due to excessive application of pesticides, the production of cucumber products has been reduced year after year. drop in quality

In addition, most of the nutrient solution formulas used in cucumber soilless substrate cultivation are general-purpose formulas, and there is a lack of special formulas for the nutritional needs of cucumber crops

The demand for various nutrient elements of cucumbers varies greatly in different growth periods, and there is no nutrient solution formula prepared according to the nutritional requirements of cucumbers in different growth periods, resulting in frequent deficiency symptoms of cucumber crops in the vigorous growth period
