A method suitable for cultivating grape in poor soil regions

Abstract

The invention discloses a method suitable for cultivating grapes in poor soil regions, comprising following steps: preparing land in a horizontal or terrace way, ditching along the contour line with width and depth of 0.8-1.2m respectively, hanging plastic films at two vertical walls at two sides of the ditch, extending the plastic films to the bottom and leaving a gap to expose 20-30cm of soil; filling high quality garden soil or improved surfical soil into the ditch, evenly adding 100-200g / cubic meter of water retention agent in the middle and lower layer of soil, and finally filling the soil till the ditch surface is shaped like a concave channel; using the films to cover from two sides to internal, planting a raw of grapes at the central part of the ditch surface, opening the films at stems of plants; and irrigating by watering on the films. The method not only can enhance use ratio of the land resource effectively to produce more high quality grape product, but also has advantages of inhibiting vegetative growth of the plants, promoting fructifying, saving rich water and being environmental friendly, therefore the method can be widely popularized and used in the regions with irrigation water sources.

Description

technical field [0001] The invention relates to the technical field of horticultural plant cultivation, in particular to a method for cultivating grapes in areas with harsh soil conditions (Gobi Desert, desert, saline-alkali land, open field or greenhouse) but with irrigation conditions. Background technique [0002] Grape is one of the most widely distributed fruit trees in my country, with 28 provinces and cities producing grapes. From the northeast region with the highest latitude to Yunnan, Guangxi, Guizhou and other places south of the Tropic of Cancer, there are grapes planted, of which Xinjiang, Hebei, Shandong, Liaoning and Henan are the main ones, and the five provinces in the production area account for 68.5% of the total production. , 63.8% of the total area. Xinjiang has unique natural conditions, suitable for the growth of grapes, and is the largest grape-producing area in my country. The Tarim area in eastern and southern Xinjiang is rich in light and heat re...

Problems solved by technology

[0007] The currently applied root zone limited cultivation techniques mostly adopt potted plants, frame box cultivation, or fully covered cultivation with plastic film at the bottom of the groove, or use 40cm thick less foreign soil for cultivation, which cannot adapt to air-dry areas (such as the Xinjiang Ring Tarim, etc. region) Munage, Red Globe and other grapes require extremely vigorous vegetative growth and large evaporation;

[0008] At present, the irrigation methods commonly used in viticulture are mostly flood irrigation, which brings troubles to water use efficiency, orchard microclimate control, and pest control. In the modern society where water resources are tight, it is an irrigation method that must be eliminated; and drip irrigation Although modern irrigation methods such as drip irrigation and seepage irrigation can save water, they are only used in limited applications. Since drip irrigation and seepage irrigation require a considerable initial capital investment, and have high requirements for water quality, water treatment technology and equipment, Otherwise, it is easy to cause pipeline (mouth) blockage, affect the irrigation effect, and greatly limit its popularization and application.

[0009] Although traditional guest soil cultivation has many applications like potted plants, due to the great influence of soil texture on plant growth, there are huge differences in water and fertilizer retention, water and fertilizer release and supply, ventilation and other aspects of soil from different sources and textures.
