Senecio cineraria plug seedling culture transplanting method

Abstract

The invention provides a senecio cineraria plug seedling transplanting method, which comprises the following steps of (1) seedling culture disc and plug substrate preparation; (2) seeding: in mid February to mid March, seedling culture trays are sterilized, and are then filled with substrates, soaked seeds are uniformly mixed with fine sand, the mixture is spread on the surface of the substrates, then, a layer of vermiculite is covered, the watering is carried out after the seeding, finally, a film covers the seedling culture trays; the seedling culture trays are put into a greenhouse after the seeding, and certain temperature and humidity are maintained; after young seedlings begin to sprout, the attention needs to be paid on the ventilation and sun shading, the temperature and the humidity are properly lowered for preventing vain growth, and the seedling thinning and weeding are carried out in time; when 80 percent of young seedlings grow out of the soil, the film can be uncovered, and the watering is carried out every day; (3) seedling separation; (4) fixed planting; (5) field management; (6) harvesting. The senecio cineraria plug seedling transplanting method has the advantages that the harvesting period is brought forward to more than 15 days, the growth period is correspondingly prolonged by more than 15 days, the average acre yield is improved from 35 kg to more than 40kg, and the average seed consumption per acre of land is reduced from 1000g to 200g.

Description

technical field [0001] The invention relates to a method for growing and transplanting snow chrysanthemum seedlings in plug trays. Background technique [0002] Snow chrysanthemum, native to the midwestern region of the United States, is a plant widely cultivated in western China.
