Fast Carya cathayensis Sarg. container seedling matrix and method thereof

Abstract

The invention relates to a Carya cathayensis Sarg. container seedling raising matrix, which is formed by blending the following raw materials by weight: 34-44 parts of peat, 25-35 parts of perlites, 25-35 parts of garden soil and 1 part of calcium magnesium phosphate. The fast Carya cathayensis Sarg. container seedling raising method consists of the following eight steps of: first, preparation ofthe container seedling raising matrix according to the weight parts of raw materials, second, seed collection and pretreatment, third, warming and germination acceleration of Carya cathayensis Sarg. seeds, fourth, seed potting, fifth, thermal insulation for overwintering, sixth, top dressing of the seedlings, seventh, grafting, and finally outplanting in December. From seed collection to outplanting, only 16 months are needed for robust grafted seedlings that can be transplanted to a land for growing field crops. The method of the invention overcomes the defects of slow growth speed of Carya cathayensis Sarg., long outplanting time, heavy matrix, and inconvenient ball transplanting on mountains in prior art. The seedling raising cycle is shortened, so that the batches of seedling supply to society can be increased, and the utilization rates of a thermotank, a seedbed, a greenhouse and other equipment can also be improved, thus substantially increasing the economic benefits of seedlingproduction units.

Description

technical field [0001] The invention relates to a substrate and a method for raising seedlings of forest fruit trees, in particular to a substrate and a method for fast-growing hickory seedlings in containers. Background technique [0002] Hickory nut (Carya cathayensis Sarg.), belongs to Juglandaceae Hickory plant. It is suitable for growing in limestone mountains, concentrated in Anji, Lin'an, Chun'an, Zhejiang, and Ningguo, Jixi, Anhui. It is a precious dried fruit and woody oil tree species unique to my country, and is also an excellent ecological and economic tree species. With the improvement of people's living standards, hickory nuts have become an ideal high-grade protein fruit, which has more unique advantages in nutritional value, health care, beauty and medicinal effects. Therefore, it is more and more favored by people, and the supply of products exceeds demand. The long childhood period of hickory, slow growth in the early stage, the long seedling period of mou...

AI Technical Summary

Problems solved by technology

Formula ② 50% organic matter (such as discarded mushroom sticks) + 50% yellow core soil, plus 3% calcium magnesium phosphate fertilizer, the substrate is heavy, and it is inconvenient to move and transplant with soil

The key point of this strong seedling technology is to cut the roots three times before and after, and it spans three years (about 27 months) from the beginning and the end of the seed collection to the nursery, and the cultivation period is too long
