Pear tree growing period and dormancy period whole-course under-mulch drip irrigation cultivation method

Abstract

The invention relates to the technical field of agricultural planting, in particular to a pear tree growing period and dormancy period whole-course under-mulch drip irrigation cultivation method. The drip irrigation technology is used in the whole course of each of the growing period and the dormancy period, and soil moisture infiltration and soil moisture proportion are controlled. In actual production, discoveries obtained by comparing the pear tree whole-course under-mulch drip irrigation cultivation technology with traditional pear garden broad irrigation under the same climate and soil conditions include: whole-course under-mulch drip irrigation pear tree dripping amount is 350-415m<3> / mu, but traditional broad irrigation pear garden irrigation amount is above 750m<3> / mu, water is actually saved by about 45-53%, whole-course under-mulch drip irrigation enables the soil moisture infiltration and soil moisture proportion to be controlled in the whole course so that moisture supply is more reasonable, and healthy growth of pear tree root systems is benefited; and per mu yield of pear trees can reach 3900-4200kg, and commodity fruits with single weight more than 200g are 3400-3600kg, but per mu yield of pear gardens by traditional broad irrigation is 3500kg, commodity fruits with single weight more than 200g are 2660g, therefore, pear yield is increased by 11-20%, the quantity of commodity fruits is increased by 28-35%, and fruit quality is improved remarkably, and better economic benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method of pear tree under film drip irrigation during the whole growth period and dormancy period. Background technique [0002] At present, in the domestic fruit tree drip irrigation planting technology, the research on pear tree drip irrigation technology is relatively extensive. The research mainly includes pear tree drip irrigation cultivation technology, pear tree drip irrigation mode, system and the impact of drip irrigation on pear tree growth, yield and fruit quality. Published related research reports mainly solve the irrigation problem of pear trees during the growth period, and there are no reports on the use of drip irrigation technology throughout the growth and dormancy periods of pear trees. The main reason is that pear trees are deciduous fruit trees, which are mainly planted in northern regions. Generally, fruit trees in the north need...

Problems solved by technology

However, in actual use, it has been found that large-scale flood irrigation before overwintering not only wastes water resources, but also cannot provide the water needed for the growth of northern fruit trees in the dormant period, especially perennial pear trees, which will cause fruit trees to fail to survive the winter or affect the growth of fruit trees in the next year have adverse effects
