A kind of cultivating method for keeping alive, premature and high-yield of Huangguan pear in arid area of ​​Northwest China

Abstract

The invention discloses a live-keeping early high-yield cultivation method for crown pears in the northwest arid region.According to the method, infection and harm of crown pear black shank are fundamentally solved by putting forth effort, combining the characteristics that the northwest arid region is rich in photo-thermal resources, excellent in selenium-enriched water quality and the like and starting with the technological means such as a crown pear cultivation mode, a moisture preserving and live promoting method, water and fertilizer management, pest and disease damage prevention and control, instrument angle opening, flower and fruit management and a safe wintering method, therefore, the survival rate of the crown pears is increased, and the obvious effect on achieving the early high-yield is achieved; compared with planted traditional crop, the economic benefit per mu is increased by 50% or above, and not only can a third of water be saved through furrow irrigation, but also the phenomenon that the black shank occurs in large area due to the fact that seedling grafting openings are immersed into water and soil can be avoided.

Description

technical field [0001] The invention belongs to the technical field of horticulture and cultivation, and in particular relates to a cultivation method for keeping alive, premature and high-yielding crown pears in the arid region of Northwest China. Background technique [0002] Crown pear is an early-maturing pear variety. It has the advantages of early fruit, early abundance and strong disease resistance. It matures early, and it will be on the market around the end of July. The appearance is beautiful, the fruit is oval, the average is about 250 grams, the fruit surface is yellow and white, and the fruit is small like a yellow crown apple. Excellent quality, thin skin, thick flesh, fine quality, soft and juicy, sweet and sour flavor with honey aroma, small core, high edible rate, few stone cells, 11.6% soluble solid content. [0003] The biological characteristics of Crown pear are: 1. Strong growth potential. The height of the 8-year-old tree is 4.35 meters, the trunk...

AI Technical Summary

Problems solved by technology

However, for decades, drought, water shortage, spring frost and winter cold have been the bottlenecks restricting the large-scale development of the fruit industry. The traditional pear tree cultivation method has caused "unacceptable water and soil" in the local area, which is mainly manifested in low survival rate and early and high yield. Unsatisfactory, the natural conditions of spring frost and winter cold affect the survival, flowering and fruit setting of saplings, and the manpower and material resources for tree shape cultivation and pest control are relatively large

In addition, the difficulty of preventing black shank disease is also the main factor affecting the large-scale development of the crown pear industry
