Embodiment 1

[0033] The applicant conducted an experiment in Mengcha Village, Mizhi County, Shaanxi Province. The three-year-old pear jujube in the mountainous area had 111 plants per mu. Under the same conditions as other measures, fertilization was carried out on May 16, 2008, during the leafing stage of the jujube tree. Once, the fertilizer applied to each jujube tree is: 0.6-0.8kg of urea, 1.0-1.4kg of superphosphate, and 0.4-0.6kg of potassium sulfate; once during the flowering period of the jujube tree, the fertilizer applied to each jujube tree is: Urea 0.1-0.2kg, potassium sulfate 0.1-0.2kg. Jujube trees are fertilized once during the fruiting period, and 0.2-0.3kg of urea is applied to each plant. The average yield of these jujube trees in that year was 1130kg, which was 19% higher than traditional fertilization.

Embodiment 2

[0035] The applicant conducted an experiment in Mengcha Village, Mizhi, Shaanxi Province. For the 6-year-old pear jujube in the mountainous area, 111 plants per mu, under the same conditions as other measures, fertilization was carried out on May 16, 2008 at the stage of the jujube leaves. Once, the fertilizer applied to each tree is: urea 1.0-2.0kg, superphosphate 2.0-4.0kg, potassium sulfate 0.7-1.0kg; fertilize once during the flowering stage of jujube trees, and apply urea 0.1-0.2kg to each tree , potassium sulfate 0.1-0.2kg. Fertilize once during the fruiting period of jujube trees, and each plant needs to apply 0.4-0.5kg of urea. The average yield of these jujube trees in that year was 1450kg, which was 21% higher than traditional fertilization.

Abstract

The invention discloses a fertilization method of Chinese jujube trees planted on a hill land and a sloping field in a drip irrigation way. The method comprises the following steps: arranging a slow-release fertilization tank just below a water outlet of a drip irrigation belt or a drip irrigation tube which is arranged around the jujube tree; putting fertilizer into the slow-release fertilization tank while fertilizing, then covering the fertilizer with powdered straw so that irrigation water flow from the drip irrigation belt directly drips into the slow-release fertilization tank, passes through the powdered straw layer and dissolves the fertilizer and the fertilizer slowly infiltrates into a root layer of the jujube tree around the slow-release fertilization tank along with the water. In addition, bottom of the slow-release fertilization tank is impervious, which reduces infiltration speed and infiltration depth of fertilizer water and has the function of the upper straw on preventing evaporation, can improve utilization ratio of the fertilizer and reduce consumption of the fertilizer, and benefits to increase yield of the red jujubes. Compared with the traditional fertilization method, the present fertilization method helps increase the fertilization efficiency by 2-3 times and improve the fertilizer efficiency by 26%. The fertilization method has very important actual meaning and use value for promoting a high-efficiency water-saving drip irrigation technology and developing economic forest industries of China, especially fruit industries and forest industries in areas in an acute shortage of water of a mountainous region.

Description

technical field [0001] The invention belongs to the technical field of farmland irrigation, and relates to irrigation of mountainous lands, sloping lands, hilly orchards, and woodlands, and in particular to a fertilization method for jujube trees in mountainous lands and sloping lands under the condition of drip irrigation. Background technique [0002] my country is a country with serious water shortage. The arid and semi-arid areas account for 2 / 3 of the total area. Drought and water shortage have not only seriously affected the agricultural development of our country, but also affected the development of the ecological environment and forestry. my country is a mountainous country. The area of ​​mountains and slopes is more than twice that of plain farmland. Irrigation of mountains and slopes and simultaneous fertilization during irrigation are important ways to improve production efficiency. Reasonable fertilization is the key link to improve irrigation efficiency. For a...
