Problems solved by technology

[0004] The water and fertilizer integration technology has greatly improved the utilization rate of irrigation water and fertilizer, reduced the amount of fertilizer application, and reduced the water consumption. However, for most fruit trees, the water and fertilizer integration technology still exists in the concept. How to save water and fertilizer At the same time, the effect of traditional fertilization is still in the exploratory stage, especially for the emerging economic forest tree species Pingou hybrid hazel is difficult to implement

Embodiment 1

[0037] 1. Test location and test species

[0038] Test location: Jinzhou Heishan Hazelnut Test and Demonstration Base of Liaoning Economic Forest Research Institute, Jinzhou Heishan Xinxing Town.

[0039] The tested variety: Dawei, the tree age is 7-8 years old, the average crown width is 1.5-1.8 meters, and the tree height is 1.8-2.2 meters.

[0040] 2. Experimental design and processing methods

[0041] Field test design: The fertilization test was repeated 3 times, and the random block field test design was used, with 150 test trees per treatment. The irrigation test was repeated 3 times, and the randomized block field experiment design was used to treat 150 test trees.

[0042] The level of fertilization and drip irrigation is designed as: pure N, P 2 o 5 、K 2 O fertilization amount / hm 2 + Drip irrigation treatment; base fertilizer applied in early May in spring: decomposed chicken manure 41250.0kg / hm 2 , Effective Ca 412.8kg / hm 2 , Effective Mg 53.3kg / hm 2 ; Earl...

Embodiment 2

[0055] Pure N, P 2 o 5 、K 2 O fertilization amount / hm 2 It is half the amount of Example 1, and the base fertilizer is applied in the first ten days of May in spring: decomposed chicken manure 41250.0kg / hm 2 , Effective Ca 412.8kg / hm 2 , Effective Mg 53.3kg / hm 2 ; Early spring fertilizer: apply water-soluble fertilizer (effective nitrogen, phosphorus and potassium content is 15%-30%-15%) 172.01kg / hm 2 , Urea 117.65kg / hm 2 , Potassium sulfate 42.41kg / hm 2 ; Fertilizer at the end of spring: apply water-soluble fertilizer (effective nitrogen, phosphorus and potassium content is 15%-30%-15%) 229.35kg / hm 2 , Urea 98.92kg / hm 2; Summer fertilizer: apply water-soluble fertilizer (effective nitrogen, phosphorus and potassium content is 20%-20%-20%) 172.02g / plant, urea 98.92g / plant, potassium sulfate 25.20kg / hm 2 ; Autumn fertilizer: apply water-soluble fertilizer (effective nitrogen, phosphorus and potassium content is 20%-20%-20%) 86.01kg / hm 2 , Urea 20.51kg / hm 2 , Potassiu...

Abstract

The invention provides a water and fertilizer integrated fertilization method for corylus heterophylla corylus avellana trees, and belongs to the technical field of agricultural irrigation and fertilization. The fertilization method comprises the step of applying early spring fertilizer, late spring fertilizer, summer fertilizer and autumn fertilizer to the corylus heterophylla corylus avellana trees in a drip irrigation mode. According to the fertilization method, the yield of the corylus heterophylla corylus avellana trees is effectively increased, the fertilizing amount and the irrigation amount are greatly reduced, a large number of resources are saved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation and fertilization, and in particular relates to a method for fertilizing Pingou hybrid hazel with water and fertilizer integration. Background technique [0002] my country is one of the countries with serious shortage of water resources. The agricultural water consumption accounts for 63% of the country's total water consumption, and the agricultural irrigation water accounts for 90% of the agricultural water consumption. The shortage of agricultural water seriously restricts the sustainable development of agriculture in our country. Due to the relatively backward agricultural irrigation technology also causes a lot of waste of water resources. At present, with the popularization and improvement of garden management technologies such as Pingou hybrid hazel pruning technology, improved seed matching technology and integrated pest control technology, fertilizer and water management...
