Method for improving survival rate of potted tea tree

Abstract

A method for improving the survival rate of a potted tea tree includes the following steps: 1) substrate preparation: washing quartz sand with clean water repeatedly, evenly mixing the quartz sand and a water absorbent, and then putting a mixture of the quartz sand and the water absorbent in a polyethylene pot, using a stone to block a vent opening formed in the bottom of the pot to prevent a substrate from flowing out with water, wherein the upper substrate is aligned with a pot opening; 2) planting: planting tea seedlings into the pot during the middle of ten days of March to the end of April, wherein 1-6 tea seedlings are planted into one pot, the tea seedlings are evenly distributed in the pot, a white polyethylene plastic bag sleeves the lower part of the pot and is tied to the top of the pot through handles, the upper part of the pot is covered with a black polyethylene plastic bag, holes with the same number of the tea seedlings are formed in the bottom of the black polyethylene plastic bag, the tea seedlings can pass through the holes when being covered, the bottom of the black polyethylene plastic bag is tightly attached to the substrate, the two handles are arranged in the center of the pot, the outer part of the white polyethylene plastic bag is tied tightly, and the planted polyethylene pot is arranged on a tray; and 3) management after planting: irrigating the tea seedlings with clean water and a working nutriment solution regularly. The substrate is scientific in composition, is suitable in nutriment supply, can ensure water supply, air permeability and persistence.

Description

technical field [0001] The invention relates to planting technology in the field of horticultural technology, in particular to a method for improving the survival rate of potted tea trees. Background technique [0002] Soilless cultivation is a method of cultivating plants with other things (quartz sand, vermiculite, peat, sawdust, plastic, etc.) without soil, including hydroponics, fog (air) cultivation, and matrix cultivation. In the mid-19th century, W. Knop and others invented this method. By the 1930s, this technology began to be applied to agricultural production. In the 21st century, people further improved the technology, making soilless cultivation develop. Years of practice have proved that soybeans, beans, peas, wheat, rice, oats, sugar beets, potatoes, cabbage, leaf lettuce, tomatoes, cucumbers and other crops have higher yields in soilless cultivation than in soil cultivation. [0003] Tea tree soilless cultivation is a common method of tea tree cultivation, ...
