Rapid walnut orchard establishment technology for direct seeding orchard establishment

Abstract

The invention relates to a rapid walnut orchard establishment technology for direct seeding orchard establishment and belongs to the technical field of cultivation. The technology is a method for sowing seeds of thick-skin walnuts or pecans serving as stocks artificially in a single row according to a ruled spacing in the rows and spacing between rows by utilizing a cultivation mode of establishing an orchard through onsite-stock grafting; the cultivated variety is grafted in next year; seedlings are remained according to required spacing in the rows and spacing between rows in the third year. Through the walnut direct seeding orchard establishment technology, seedlings are in-situ and are not subjected to the processes such as lifting of seedlings, transplanting and revival of seedlings, and roots are not damaged, so that survival rate of afforestation is high, the orchard establishment speed is fast, the survival rate of over-wintering is improved greatly, the trees are neat and consistent, and convenience is brought to management. The cost of the walnut direct seeding orchard establishment is low, the time taken for orchard establishment is short, and fast effect is achieved.

Description

Technical field [0001] The invention relates to a fast walnut orchard construction technology for direct-broadcasting orchard construction, belonging to the field of cultivation technology. Background technique [0002] The walnut belongs to the Juglans family, a deciduous tree with pinnate compound leaves, and the tree height is generally 15-20 meters. Flowering period is from the end of April to the beginning of May, unisexual and monoecious. The fruiting period is October, the fruit is nearly spherical, 3-5 cm in diameter. The exocarp is fleshy, gray-green with brown spots. The endocarp is hard, wrinkled, and yellowish brown. The fruit is collected before and after the white dew, the outer skin of the fruit is rotten, and the inner fruit is rinsed, aired, and cleaned. This is what people call "walnut". [0003] Walnut tree, deciduous tree, up to 35m, gray-white bark, shallow longitudinal cracks, lamellae pith, young branches apex with fine hair; 2-year-old branches are often...

AI Technical Summary

Problems solved by technology

Fruit growers consider the uniformity and early yield when building orchards, and often use finished seedlings to build orchards. Not only do they need to pay a lot of money to purchase seedlings, but they also need to dig large pits and water many times during planting. The survival rate is low, and part of the root system of the seedlings is damaged after the seedlings have been raised, transported, and spent a long time
