Problems solved by technology

Since live broadcasting of seeds is greatly affected by the natural environment, insect damage and rodent damage are serious, seedling emergence is irregular, and seedling emergence rate is low. It is necessary to sow 6-7 seeds per hole, and the amount of seeds per mu is 200-300g. In extreme drought climate , it is often necessary to replant many times in production, which is labor-intensive and time-consuming

Embodiment 1

[0044] floating nursery

[0045] (1) Choose a place where the terrain is flat, the water source is convenient, the water quality is pollution-free, and the ventilation is sunny, and a steel frame seedling cultivation shed with a length of 6.0m, a width of 1.4m, and a height of 1.2m is built, and a white plastic film with a thickness of 10 wires is used as the top film, and Cover one layer of sunshade net with 75% sunshade rate on the top film. 36 floating seedling trays can be placed in each seedling shed;

[0046] (2) Adopt a black film with a length of 7.8m, a width of 2.2m, and a thickness of 12 wires as the pond film, and fix it along the grooves around the nursery shed to make a nursery pond with a height of about 20cm;

[0047] (3) Inject tap water or well water with a depth of 10cm. Apply 100g of 75% carbendazim and 100g of dexazone to each nursery pond for water disinfection and disease prevention. At the same time, apply N:P:K ratio of 19:19 :19 compound fertilizer ...

Abstract

The invention provides a seedling raising method of industrial hemp. The method adopts a floating seedling raising method, is convenient to operate, is less affected by natural climate change, has controllable environment, uses less seeds, has short seedling raising period, cultivated seedlings are neat and consistent, and the emergence rate is as high as about 93%, and thus the problems of low emergence rate, irregular emergence and the like existing in direct seeding of industrial hemp field seeds are effectively solved.

Description

technical field [0001] The invention relates to the technical field of industrial hemp seedling cultivation, in particular to a method for raising industrial hemp seedlings, in particular to a method for floating seedling cultivation of industrial hemp. Background technique [0002] Industrial hemp is cannabis with a toxic component tetrahydrocannabinol (THC) content of less than 0.3%. Industrial hemp has high economic value and is widely used in health care, food, textiles, bioengineering materials, papermaking and other fields. In recent years, the development of new drugs by extracting the medicinal component cannabidiol (CBD) from flowers and leaves has gradually become an important field for the development of the industrial hemp industry. At present, the artificial cultivation of industrial hemp mainly adopts the direct seeding method. Since live broadcasting of seeds is greatly affected by the natural environment, insect damage and rodent damage are serious, seedlin...
