Soilless cultivation and disease control method of elm sprouts

Abstract

The invention discloses a soilless cultivation and disease control method of elm sprouts. The method includes sealing a greenhouse, using mist spray of a 100-mutiple formaldehyde solution to fumigate the greenhouse for 24 hours, ventilating the greenhouse, using the greenhouse after a week, cleaning tools like sprouts plates, seed soaking buckets and strainers with a 0.1% potassium permanganate solution, selecting silver sand as base materials, using the 100-mutiple formaldehyde solution to spray the silver sand and then fumigate the silver sand for 24 hours, washing the silver sand with clean water for 2-3 times, airing the silver sand for 5-7days, soaking selected seeds with warm water with the temperature of 55 DEG C for 10 minutes, wherein consumption of water is 5-10 times that of elm seeds, continuously stirring the warm water until water temperature drops to 20 DEG C and then soaking the seeds for 6 hours, washing the seeds with water for 2-3 times, laying 0.5cm of the silver sand in sterile sprout plates, evenly sowing half a kilo of the elm seeds, laying 0,5cm of the silver sand again, putting the sprout plates in the greenhouse after the sprout plates are filled with the seeds and the silver sand, watering the seeds, from then on, using less water to water the seeds with a watering can for 3-4 times each day to enable the silver sand to keep moist, keeping the temperature at 22-28 DEG C in first three days, keeping the temperature at 20-25 DEG C in 4-5 days, keeping the humidity within 75%-85%, covering a single-layer sunshade net in the 4-5 days, and ventilating the greenhouse for 1-2 times each day until the elm sprouts grow more than 5cm in 7-8 days.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to the field of soilless cultivation and disease prevention of elm sprouts. Background technique [0002] Although my country's soilless cultivation technology has been developed for many years, it cannot be uniformly applied to the soilless cultivation of elm sprouts because of the different requirements for each plant seed. The previous methods of disinfection measures, temperature, temperature control or production process The disease control of all can not be applied on the soilless cultivation and disease control of elm sprouts. Contents of the invention [0003] The object of the present invention is to provide a method for soilless cultivation and disease control of elm sprouts. [0004] The object of the present invention is achieved like this: it is through the mode of soilless cultivation, comprises airtight greenhouse, spray fumigation with 100 times of for...
