Problems solved by technology

[0005] Therefore, in the Qinghai plateau area, due to its special geographical location and changing climate characteristics, conventional budding and grafting methods have been used for seedling cultivation for a long time. There are difficulties in grasping the time of seedling cultivation, low survival rate of grafting, low preservation rate of the year, and average unit area Problems such as low seedling emergence

Embodiment Construction

[0023] The specific implementation of the present invention will be described in conjunction with the examples.

[0024] Choose an empty room or a built-in bed in the greenhouse. The hotbed in the greenhouse should avoid direct sunlight. The adjacent walls on both sides of the room are surrounded by 10cm thick high-compression foam to build a rectangular bed groove with a width of 3m, a depth of 0.6m, and a length determined by the terrain, and the bottom of the bed groove is paved with high-density foam. On the foam board at the bottom of the bed groove of the hotbed, lay geothermal wires in a row-to-row manner, and the geothermal wires are connected to the automatic temperature controller; fill 10 cm of dry substrate above the geothermal wires; lay plastic cloth above the substrate, and cover the entire hotbed with plastic cloth Bed body; fill 3-5cm dry matrix above the plastic sheeting. The matrix material is sawdust.

Abstract

The invention relates to a seedling growing method for walnuts, in particular to a method of indoor seedling growing in a hotbed for walnuts in a plateau region. The method of indoor seedling growing in the hotbed includes the steps of awaking stocks and scions, grafting in the hotbed, cooling for seedling hardening, transplanting and the like. According to the method of indoor seedling growing in the hotbed for the walnuts in the plateau region, the grafting healing cycle is short, the seedling emergence rate per unit is large and can reach 200 plants / m<2>, the grafting survival rate is high and stable, and the influence on the grafting survival rate by the vagaries of climate in the plateau region is small; the grafting cycle is long, and the method of indoor seedling growing in the hotbed can serve as one seedling growing mode for the walnuts in the plateau region.

Description

technical field [0001] The invention relates to a method for raising walnut seedlings, in particular to a method for raising walnut seedlings in an indoor hotbed in plateau areas. Background technique [0002] The current main ways of raising walnut seedlings include the following two methods: [0003] Field budding system: budding in summer, depending on the location, the time of budding varies from place to place every year, and the cost is low. Bud grafting in plateau areas is seriously affected by climate change, and the time of year is different. It is difficult to grasp the best time. The survival rate of grafting is unstable, and it is difficult to survive the winter. The preservation rate of the year is less than 20%. [0004] Field grafting system: spring grafting, the grafting time varies from region to region each year, and different methods show different survival rates. Compared with bud grafting, the cost is higher. Outdoor branch grafting in plateau areas is...
