Problems solved by technology

Water spinach likes an environment with high temperature and sufficient light. The traditional cultivation season is generally in summer and autumn to ensure the robust growth of water spinach. Soilless cultivation technology undoubtedly broadens the planting time of water spinach. It is soilless cultivation in greenhouses, the cost of water spinach planting is still high, and when planting in spring, especially in southern my country from March to May is a rainy season, it is easy to cause the photosynthesis of water spinach to weaken, aff

[0029] 1. Materials and methods

[0030] 1.1 Materials

[0031] The water spinach for testing is "Thailand water spinach".

[0032] 1.2 Experimental design

[0033] The experiment was carried out in a plastic greenhouse. Sow spinach seeds in 50-hole plug trays, the seedling substrate is coconut bran: perlite = 7:3, transplant seedlings when the three leaves of the vegetable seedlings are in one center, the nutrient solution formula is Huanong Leafy Vegetable B formula, spray every 3 days Apply organic carbon fertilizer once, and spray 4 times in total. Choose plastic greenhouses to avoid the impact of rain on foliar fertilizers. The test set 4 treatments (see Table 1), 6 repetitions, 6 holes per repetition, 2 plants in each hole, arranged randomly, and carried out the determination of various indicators after 14 days of transplanting.

Abstract

A method for improving quality of water spinach is used during soilless culture growth of the water spinach. The method comprises the steps that an organic carbon fertilizer is taken as a leaf fertilizer of the water spinach for a spraying treatment in a rainy season after culture of the water spinach. The organic carbon fertilizer is an organic carbon transparent solution obtained by processing of kitchen rubbish, wherein the content of organic carbon is 25-50 mg/L. Urea with the proportion of 0.1% is also contained in the organic carbon fertilizer. During the spraying, the organic carbon fertilizer shall be sprayed uniformly from top to bottom on the leaf surface of a water spinach plant; the spraying shall be carried out for one time every two to four days; and the spraying shall be carried out for four to five times in total. According to the method provided by the invention, the leaf surface spraying of the organic carbon fertilizer is performed on the soilless-cultured water spinach, so that the water spinach can be nourished during the growth; the problem about harms brought to the water spinach under a dim light stress situation can be relieved; the problem about the poor quality of the water-cultured water spinach under the dim light stress situation can be effectively solved; yield and taste of the water spinach can be improved; and adaptability and stress tolerance of the water spinach in the stress situation can also be enhanced.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method capable of improving the quality of water spinach cultivated without soil. Background technique [0002] In recent years, soilless cultivation technology, especially hydroponics, has developed rapidly. Hydroponic vegetables mean that most of the roots grow in the nutrient solution layer, and provide nutrients, water, oxygen, etc. through the nutrient solution. The hydroponics method can not only avoid soil diseases and insect pests, but also reduce the amount of pesticides, improve the yield and quality of crops, save water, save fertilizer and labor compared with soil cultivation, and more importantly, it can provide real-time environmental conditions, Three-dimensional planting, space saving, industrial production. Therefore, hydroponic vegetables are developing rapidly. However, although hydroponic vegetables grow rapidly and have high yields, their quality is sli...
