Fast Ipomoea aquatica seedling culture method

Abstract

The invention relates to the technical field of vegetable seedling culture and discloses a fast Ipomoea aquatica seedling culture method. The method includes the steps of S1 , preserving the old stalks of Ipomoea aquatica in a cellar at the end of the previous year, and keeping the temperature in the cellar at 18-20 DEG C; S2, arranging electric heating wires on a seedling culture bed, wherein a first layer of fine soil covers the electric heating wires; S3, taking out the old stalks from late January to early February of the next year, flatly laying the old stalks on the first layer of fine soil, and covering the old stalks with a second layer of fine soil to allow 70-80% of the height of the old stalks to be covered by the second layer of fine soil, wherein the water content of the two layers of fine soil is 50-60%; S4, covering the seedling culture bed with a transplant-film arched shed, and turning on the electric heating wires to keep the temperature of the two layers of fine soilat 20-40 DEG C to obtain transplantable Ipomoea aquatica seedlings after the old stalks grow roots and germinate. The method has the advantages that the fine soil is heated through the electric heating wires, the rooting and germination of the Ipomoea aquatica are accelerated, the rooting and germination of the Ipomoea aquatica can occur 20-30 days earlier, constant temperature is achieved, and old stalk rot caused by cold weather is avoided.

Description

technical field [0001] The invention relates to the technical field of vegetable seedling cultivation, in particular to a rapid seedling cultivation method of water spinach. Background technique [0002] Water spinach (scientific name: water spinach, also known as: Tongcai, water spinach or rattan vegetable) is one of the most popular vegetables, which can be fried or boiled in soup. In addition to being edible for vegetables, it can also be used medicinally. It can be taken orally to relieve food poisoning, and applied externally to treat fractures, ascites and unknown swelling. Water spinach is also a good food for poultry, livestock and fish. [0003] At present, the water spinach sold on the market is mainly artificially planted. If the water spinach is directly planted in the field, the survival rate is low, so seedlings need to be raised before planting. The spinach seedlings can only be transplanted into the field after sprouting. The existing artificial seedling ra...

Problems solved by technology

[0004] The present invention proposes a rapid seedling raising method of water spinach, which solves the problem that the seedling raising progress of water spinach in the prior art is relatively slow, and the old stalks may rot during the seedling raising process
