Problems solved by technology

[0005] Aiming at the above-mentioned technical problems in the prior art, the present invention provides a method for improving the soil of asparagus continuous cropping obstacles. The method for improving the soil of asparagus continuous cropping obstacles should solve the problem of excessive application of asparagus due to long-term continuous planting of asparagus in the prior art. Fertilizers, as well as the perennial nature of asparagus, lead to a growing technical problem of soil barriers to continuous cropping

Embodiment 1

[0023] According to the characteristics of asparagus crops, combined with the actual production of Chongming asparagus, and according to the principles of practicability, scientificity, and ease of operation, a set of asparagus soil ecological restoration and improvement integrated technology suitable for the sustainable growth of Chongming asparagus is formulated:

[0024] ① Remove the film and wash the salt: In the late stage of asparagus cultivation, its output has dropped sharply, and the low benefit is not as good as before. Therefore, the roof film of the greenhouse is removed half a year in advance (in the spring of the stubble year), and the leaching effect of natural rainfall in spring and summer is used. It can reduce soil salt content and effectively improve soil physical and chemical properties.

[0025] ②Mechanical deep plowing: After the old asparagus is eliminated, the soil must be plowed to a depth of more than 50cm, so that the bottom soil and the soil of the p...

[0035] 1 Materials and methods

[0036] 1.1 Test soil

[0037] The test site is Hexing Horticultural Farm in Chongming County, Shanghai, with an area of ​​167hm 2 , About 30% of the asparagus has been planted for more than 10 years, the growth and yield of the plants have seriously declined, and the soil has serious obstacles to continuous cropping, so stubble replacement is required. The soil for testing is sandy loess, the soil pH is 7.7, the total salt content is 18.1g / kg, the alkaline nitrogen is 376.2mg / kg, the available phosphorus is 265.7mg / kg, the available potassium is 2064.3mg / kg, and the nitrate content is 4583.0mg / kg. kg.

[0038] 1.2 Experimental design

[0039]In the experiment, the untreated conventional method was used as a control, and the asparagus soil ecological restoration and improvement technology in Example 1 was used as a comparison. After the soil treatment was completed, the asparagus colonization was carried out uniformly.

Abstract

The invention provides a method for improving soil with asparagus succession cropping obstacles. The method includes the steps of mulch removal for salt exclusion, mechanical deep ploughing, land clearing, high-temperature greenhouse closeness, soil conditioner adoption, greenhouse ditch alternation, furrow and ridge alternation and digging in winter, wherein soil conditioners are selected from one or more of corn stalks, calcium cyanamide, trichoderma agents or microorganism organic fertilizers. By the method for improving soil with asparagus succession cropping obstacles, various factors going against asparagus growth due to asparagus succession cropping obstacles can be solved fundamentally, normality in growth of succession asparaguses is realized, sustainable development of the asparagus industry is realized as well, and finally agricultural efficiency improvement, increase of farmers' income and soil protection are realized.

Description

technical field [0001] The invention belongs to the field of soil ecology, and in particular relates to a soil improvement and restoration method, in particular to a soil improvement method for asparagus continuous cropping obstacles. Background technique [0002] Asparagus (Asparagus officinalis L.), also known as Shi Diaobo, is a high-grade and valuable vegetable, known as "one of the world's top ten famous dishes". Asparagus is native to the eastern coast of the Mediterranean Sea and Asia Minor, and was introduced to China in the early 20th century. In 2008, the area of ​​asparagus in my country grew to 1.5 million mu, accounting for 40% of the world's total, and the output accounted for 60% of the world's total. At present, the scale of my country's asparagus industry has ranked first in the world, with an annual output value of more than 10 billion yuan. Asparagus has become the largest single vegetable processing trade variety in my country and one of the main vegeta...
