Problems solved by technology

[0004] Thin-shelled hickory has deep roots, and the traditional field seedling cultivation method has very few lateral roots of bare-root seedlings, poor quality of seedlings, low survival rate of transplanting, and long seedling time
For this reason, the applicant invented a method (ZL201210351736.4) to promote the occurrence of lateral roots of pecan seedlings in the same year. Compared with the traditional field seedling cultivation method, this method promotes the occurrence of lateral roots and solves the problem of transplanting survival rate. The low problem is another important technological innovation in the cultivation of pecan seedlings in my country

Embodiment 1

[0027] The inventive method ( figure 2 ), specifically include the following steps:

[0028] 1) Germination at high temperature, select plump pecan seeds with thin shells, soak the seeds for 20-28 hours after insecticide and sterilization treatment, dry the surface water after soaking, and then perform stratification treatment, and carry out high temperature at 25°C in a plastic greenhouse in early February every year Germination.

[0029] 2) Root cutting and transplanting. At the end of March every year, physically remove the roots of the sprouts and transplant them into a 13cm×20cm black polypropylene plastic nutrition bowl.

[0030] 3) Manage after transplanting, place the nutrient bowl tightly in a greenhouse with 8cm thick stones, keep the temperature in the greenhouse at 22-28°C, water thoroughly, and then water thoroughly every 15 days, from June to June At the end of August, spray a solution containing 300ppm gibberellin and 1 / 200 urea (0.5kg urea / 100kg water) every...

Abstract

The invention discloses a method for cultivating carya illinoinensis seedlings in a high-density and high-quality mode. The method includes the first step of high temperature germination accelerating; the second step of root breaking transplanting; the third step of post-transplanting management, wherein seedling cultivation basins are densely placed in a plastic greenhouse after transplantation, water is sprayed thoroughly, then water is sprayed thoroughly every 15 days, solutions containing 300ppm gibberellins and 1 / 200 urea (0.5kg of urea / 100kg of water) is sprayed every 10 days from June to the end of August, and basal stems are painted with the same solutions every 15 days. According to method for cultivating carya illinoinensis seedlings efficiently, annual carya illinoinensis seedlings can rise by 35 cm-40 cm, land resources can be fully utilized, and the number of planting in unit area is eight times that of conventional planting in unit area.

Description

technical field [0001] The invention belongs to the technical field of tree and fruit tree cultivation, in particular to a method for cultivating hickory seedlings with high density and high quality. Background technique [0002] Thin-shelled hickory, also known as American hickory, is a species of Juglandaceae and Hickory. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and fleshy, and it has a delicious taste and high nutritional value. The trunk is straight, the tree shape is beautiful, the roots are deep and the leaves are luxuriant, and it is an excellent tree species for greening and gardening around. At the same time, the wood is tough and dense, with dark red heartwood, yellow-white sapwood, high elasticity, and is not easy to deform and crack. It is an excellent timber tree species for construction and high-end furniture. Therefore, ...
