First, the choice of rootstock In different cultivation areas and ecological conditions, the choice of different types of rootstock is very necessary. Such as walnut, Kepo walnut and heart-shaped walnut have the characteristics of strong cold resistance and strong growth, and are suitable for northern China. Pterocarya stenoptera is suitable for floodplains, river valleys and moist soil conditions. The walnut anvil is suitable for valleys, hills and plains where the soil is well drained. When grafting, rootstock should be selected according to the site conditions.
Second, scion collection and storage
1. Branching and scion harvesting and storage Spikes should be cut 20-30 days before germination, or before the autumn leaves in the previous year, grow and develop long-grown branches and lengths in the selected fine trees and cutting gardens. Fruiting branches and fruiting branches with biennial branches, the scion must be thick and smooth, and the pith is small. After harvesting, bundle them well according to varieties, place them in pits or pits at the shade, and bury all the scions with wet sand. Control the temperature at 5-8°C to prevent germination.
2. Picking and scion collection and storage Bud grafting can be taken 10-15 days before grafting. Care should be taken to select good individuals and cut them from their robust development branches or long fruiting branches. Scraps should be cut immediately after harvesting to retain 1-2 cm petioles to reduce water evaporation. If the number of grafting is small, it can also be followed by others. For storage, place it in a cool, cool place and insert the scion in the wet sand. Spray water at any time to prevent shrinkage. When you need to collect scions from a remote location, they must be packaged in moist moss or wood chips, and sealed with pouches or hemp sheets before they can be shipped.
Third, the grafting period and methods Walnut grafting period, due to different climates, all localities should be based on the characteristics of walnut phenology in this region, select the appropriate grafting period. After entering the vigorous growth period, common rootstocks have less injurious flow, active layer formation, and vigorous physical activity, which is beneficial to wound healing. According to this feature, the branches are mostly in the period from late March to mid-April, and the buds are mostly carried out in the bold growth stage of the new shoots, and from late June to late August the high humidity and high temperature environment (after rain Without sunlight, noon) is carried out and the survival rate is high. Grafting moves faster. If you use the buds on the first year, you can also do it in the spring.
Grafting methods include grafting, splicing, knife-and-half-abdomen, cutting-skin tongue-jointing, and double-tongue-joining. Bud-splicing includes "T"-shaped grafts, square-bud grafts, tongue-shaped bud grafts, and improved bag-splicing. The method of operation is basically the same as the method of general fruit tree grafting.
Seed Grading Machine
The Seed Grading Machine include a Bucket Elevator,and it is drived bu two vibratory motors that lead to long life cycle and no maintenance cost.It can grade all types grain and seed,just by changing the inside sieve mesher which is very easy.
The Seed Grader can be used for wide range of seed or grain, such as wheat , maize, rice, sunflower seed, soybean, peas, lentils , kidney beans etc.
