Product Title: Northern Pointed Whitehead Road Walnut Kernels
Garden selection
Walnut is not strict on environmental conditions, as long as the average annual temperature of 9,16? above the annual rainfall of more than 800 millimeters can be planted. Walnut adaptability of the soil is relatively wide, but because it is a deep-rooted fruit trees, and resistance is weak, should choose deep fertile, strong water retention loam is more suitable. Walnut is a light-loving fruit tree, requires sufficient light, in the mountainous areas of the establishment of the garden should choose the southern slope is better.
Planting
In order to early results and improve the unit area yield, should implement dwarfing and dense planting cultivation, and choose to pull the seedling, in order to early yield. Grafted seedlings after planting 2,3 years to hang fruit, 4,5 years to enter the productive period, while live seedlings need 810 years to hang fruit, 15 years to enter the productive period. At present, dense planting garden to 3x2 (mu planted 111 plants) is appropriate. Walnut is monoecious and dioecious fruit trees, and the same plant on the female flowers and male flowers generally do not bloom at the same time, so the requirement of pollination between different plants, therefore, only into a piece of walnut planted in the garden to get a good yield. Walnut to autumn (September, November) or sprouting before planting is most suitable, before planting can be dug in a large hole (length, width, depth of 80 cm) layered pressure into the organic fertilizer, phosphate fertilizer, soil, and then planted in the hole on the water, watering the root water, and cover the tree plate with weeds in order to facilitate the survival of the tree. After planting, we should set the dry in time to prevent drought dead seedlings.
Soil Management
Walnut garden deep plowing and greening or press into organic fertilizer is an effective measure for early fruiting of young trees and large tree yield, deep plowing period in spring, summer and autumn can be carried out in spring, spring in the bud before, summer and autumn in the rain after the two seasons, and combined with the application of fertilizers and will be buried in the soil weeds. Deep plowing should be carried out from the planting hole outward year by year, the depth of 60,80 cm is appropriate, but must prevent damage to the thick roots with a diameter of more than 1 cm.
Young walnut trees grow slowly, the land between the rows can be intercropped leguminous crops or green manure. Adult orchards in April and September every year with herbicides weed 2,3 times in the fall and winter plowing once.
Nitrogen and potassium are the main constituent elements of walnut, and nitrogen is more than potassium, increased nitrogen fertilizer can significantly improve the yield and quality of phosphorus-deficient soil must be supplemented with phosphorus and calcium, but also to increase the application of organic fertilizers. Fertilization of young trees should take the principle of thin application 5 diligent application, planting the year to the beginning of the germination of fertilizer, 1 time per month, to the end of September to apply a base fertilizer, 2.4 years, in March, June, August, October each year, a total of 4 fertilizer can be applied.
Adult trees (refers to grafted seedlings planted 4,5 years later) 1 time a year to apply fertilizer, fertilizer 2 times can be. Base fertilizer in the fall after picking fruit combined with soil deep plowing and greening (September, October), mu of organic fertilizer (animal and poultry manure and water) 5000 kg, 50 kg of phosphate fertilizer, 100 kg of grass ash, 15 kg of urea. Fertilizer 2 times, the first fertilizer in the germination before the application, mu 1500 kg of pig manure water, urea 20 kg. The second fertilizer in the hard core period (June, July) applied to help increase fruit weight and promote bud differentiation, can mu 2500 kg of manure water, urea 30 kg, potassium sulfate 20 kg, 20 kg of calcium superphosphate.
