Method for researching partial root drying irrigation technology of woody fruit trees

Abstract

The invention discloses a method for researching a partial root drying irrigation technology of woody fruit trees. The research method comprises the following steps of: manufacturing a root-zone root-splitting box, planting a tree seedling, performing partial root drying irrigation and the like. The root-splitting box is prepared from transparent organic glass or toughened glass with the thickness of between 2 and 3cm, the length, the width and the height of the box are all between 40 and 60cm, four small boxes in which no water can be leaked are uniformly partitioned by using a homogeneous material inside the box body, the bottom of each small box is provided with a small hole with the diameter of between 2 and 3cm, a main root of the tree seedling is cut off before the planting, and lateral roots are uniformly divided into four parts and are planted into the four partitioned small boxes; and the periphery of the root-splitting box is wrapped with a foam board with the thickness of between 8 and 10cm, and the research on partial root-zone fertilizer water is carried out after young sprouts of a fruit tree grow to 15cm. The method can be used for researching the dynamic influence of the supply space and consumption of fertilizer water of different rooting zone volumes of the woody fruit trees on the growth of tree bodies and root systems, and provides convenience for realizing the research on water conservation, fertilizer conservation, improvement on moisture utilization rate and the like.

Description

technical field [0001] The invention relates to a research method for root zone irrigation technology of woody fruit trees. Background technique [0002] China is one of the countries in the world that is extremely short of water resources. The per capita water resources are less than 1 / 4 of the world's. my country's agricultural water consumption accounts for 70% of the country's total water consumption, and the utilization rate and utilization efficiency of water resources are lower than developed countries. half of. Fruit tree is a perennial woody plant, which has the characteristics of deep root distribution, long growth cycle, and multi-year production in one planting; my country's fruit tree planting area and fruit output both rank first in the world; the fruit area reaches 9.769 million hectares, and the output is 83.941 million tons. The area of ​​dried fruit is 5 million hectares, the output is about 4.97 million tons, and the total output value reaches 194.2 billion...
