Cultivation method for utilizing nutrition bags to cultivate khasys

Abstract

The invention relates to the technical field of pinus khasys cultivation, and discloses a cultivation method for cultivating khasys by using a nutrition bag, the nutrition bag should select a non-toxic and easily degradable bag as a main body, the specification of the nutrition bag is 12 cm * 20 cm, culture medium soil in the bag is brick red soil, the humus content is 10 g / kg, the total nitrogen content is 0.5 g / kg, the total phosphorus content is 0.3 g / kg, the total potassium content is 20 g / kg, the calcium superphosphate content is 20 g / kg, and the pH value is 5.0-5.5. The manufactured nutrition bags are sequentially placed on a nursery bed. According to the method, a field open-air cultivation mode is adopted, natural growth rules are met from pinus khasys seeds to seedling outplanting, good growth efficiency is achieved by cultivating and maintaining the seedlings in the period, the cultivation and growth efficiency of the pinus khasys seedlings can be improved, meanwhile, the adaptive capacity of the pinus khasys seedlings can be enhanced, and the survival rate of the pinus khasys seedlings is increased. Therefore, the survival rate of the pinus khasys seedlings is increased.

Description

technical field [0001] The invention relates to the technical field of Simao pine cultivation, in particular to a cultivation method for cultivating Simao pine by using a nutrient bag. Background technique [0002] Simao pine is a light-loving tree species, deep-rooted, fond of high temperature and humid environment, not resistant to cold, and not resistant to dry and barren soil. , relative humidity above 80%, wide valleys with an altitude of 600~1700m, low mountains around the basin, hills and mountains on both sides of rivers, central Yunnan and Xichang, Sichuan were introduced in the same altitude area and grow well. The trunk of this species is straight and tall, growing Fast, strong stress resistance, good papermaking performance, high pulping filtration, and wide use of wood, it is an ideal short-rotation industrial timber species. It is far from enough, so it is necessary to artificially cultivate and grow Simao pine. [0003] However, in the existing method of cul...

Problems solved by technology

[0003] However, the existing method of cultivating Pinus simao with nutrition bags is relatively low in cultivation efficiency for the seeds of Pinus simao in the cultivation process, and the finished product species produced by the cultivation are uneven, and the survival rate is relatively low, which is not conducive to the later stage field planting and cultivation of Pinus simao Work
