Problems solved by technology

[0006] The purpose of the present invention is to solve the above technical problems, and to provide a planting method that can effectively reduce the accumulation of cadmium in grapes and achieve stable yields of grapes. The accumulation of cadmium in grapes, and found a planting method that basically does not inhibit the biomass of grapes and can achieve stable grape production, which not only solves the problem of heavy metal pollution, but also ensures the economic interests of grape growers

Embodiment

[0017] (1) Preparation of test soil:

[0018] The soil used for the test is non-polluted sandy loam around Wenjiang River, its basic physical and chemical properties are: pH7.09, total nitrogen 1.50g·kg -1 , total phosphorus 0.76g·kg -1 , total potassium 18.02g·kg -1 , total cadmium 1.96mg·kg -1 , Alkaline hydrolyzed nitrogen 94.82mg·kg -1 , available phosphorus 6.30mg·kg -1 , available potassium 149.59mg·kg -1 , and the background effective cadmium content in the tested soil was not detected.

[0019] In April 2016, the test soil was air-dried, ground, passed through a 5mm sieve, and 3.0kg plastic round pots (18cm high × 21cm diameter) were weighed respectively, and CdCl was added 2 2.5H 2 O analysis of pure solution, so that the concentration of cadmium in the soil is 5 mg kg -1 , and fully mix with the soil, keep it moist, and mix it again after 4 weeks of natural storage.

Abstract

The invention provides a method of growing of grapes by the effective reduction of cadmium accumulation and the complying of steady output, belongs to the technical field of crop cultivation. The method of hybrid growing of wild crowndaisy chrysanthemum and grapes is adopted for the grape-growing soil. A hybrid method of growing grapes by efficient management of the pollution of cadmium to grape is ascertained, and a method of growing of grapes by not producing inhibition effect on biomass fundamentally and the good complying of steady output is found, the pollution problem of heavy metal cadmium in the grape is effectively solved, and the stable output of grapes is guaranteed, and the economic interests of the grape growers are well preserved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting methods, and in particular relates to a planting method for effectively reducing the accumulation of cadmium in grapes and realizing stable yield of grapes. Background technique [0002] Grape (Vitis vinifera L.) is a perennial deciduous woody vine fruit tree belonging to the family Vitis genus. As one of the oldest fruit tree species in the world, it is known as the world's four major fruits together with apples, tangerines and bananas. According to statistics from the Food and Agriculture Organization of the United Nations, in 2014 China's grape planting area was about 800,000 hectares, with an output of nearly 12 million tons. In recent years, my country's grape industry has developed rapidly, and the planting area has continued to increase. An important industry, the Sichuan region has taken the lead in becoming a demonstration model for high-quality, efficient and standardized vi...
