Embodiment Construction

[0011] What is common on the market at present is mainly lettuce water-soluble formula, and the fertilization object of the present application is purple leaf lettuce, has not found the formula of the water-soluble fertilizer of relevant purple leaf lettuce at present. At present, the common lettuce nutrient solution in the market is composed of calcium nitrate 584g / T, potassium nitrate 421g / T, ammonium nitrate 48g / T, magnesium sulfate 256g / T, potassium dihydrogen phosphate 182g / T; micro-fertilizer: EDTA iron 16.8g / T T, boric acid 3g / T, manganese sulfate 2g / T, zinc sulfate 0.25g / T, copper sulfate 0.85g / T, ammonium molybdate 0.38g / T. The problem of the research of this application is to use the proportioning scheme of the water-soluble fertilizer used for planting purple-leaf lettuce under the negative pressure irrigation system. Potassium is an element that mainly affects the quality of vegetables. The content of potassium is not only beneficial to the yield of crops, but also...

Abstract

A water-soluble fertilizer for purple leaf lettuce is characterized by being composed of the following components in parts by mass: 13 parts of urea, 18 parts of diammonium phosphate, 40-50 parts of potassium sulfate, 83 parts of calcium nitrate, 25 parts of magnesium sulfate, 0.2 part of zinc sulfate, 0.02 part of copper sulfate, 1 part of ammonium ferric ethylenediamine tetraacetate, 0.3 part ofboric acid, 0.02 part of manganese chloride and 0.1 part of molybdic acid. The water-soluble fertilizer provides sufficient nutrition for the purple leaf lettuce, has stable fertility, and can guarantee nutrients for the whole process of the purple leaf lettuce planting. Compared with the conventional control, the yield is increased by 53%, the content of vitamin C is increased by 10%, the content of soluble sugar is increased by 13%, the content of anthocyanin is increased by 20%, and the content of nitrate is decreased by 20%. The yield and the quality of the purple leaf lettuce are greatlyimproved.

Description

technical field [0001] The invention relates to a water-soluble fertilizer for vegetables, in particular to a water-soluble fertilizer for purple leaf lettuce and a fertilization method thereof. Background technique [0002] Purple-leaf lettuce is a herb of the genus Lettuce in the Asteraceae family, rich in vitamin A, vitamin C and anthocyanins and other nutrients. Purple leaf lettuce has the advantages of short growth period, multiple cropping index and high yield. At the same time, planting purple leaf lettuce requires a large amount of water and fertilizers. Currently, under the condition of limited fertilizer and water resources, planting purple leaf lettuce not only needs to consider its high yield and high quality, but also needs to have a suitable water and fertilizer supply method, as well as suitable moisture. With the combination of fertilizers, the higher economic benefits of purple leaf lettuce can be obtained. [0003] The negative pressure irrigation water a...
