[0022] The present invention will be described in detail below in conjunction with specific implementation cases.

[0023] (1) Determination of the suitable width of the tree tray: From 2011 to 2017, with Beida anvil Jufeng as the test material, 4 kinds of tree tray widths of 40cm, 60cm, 80cm, and 100cm were set up, and the traditional tree tray was used as a control without any width limit. The effects of different tree tray widths on grape fruit quality were studied to determine the appropriate width of tree trays.

Abstract

The invention provides a cultivation method for inhibiting grape root system floating by planting ryegrass using under-crown soil. The method comprises the following steps: 1, under-crown soil preparation: construction of the under-crown soil having a width of 80-100 cm with the trunk of a grape vine as a center, and making of ridges having a height of 10 cm and a width of 20 cm at two sides of the under-crown soil; 2, ryegrass sowing: soil loosening of a 0-10 cm soil layer in the under-crown soil with a small rotary cultivator or a spade, broadcast sowing of ryegrass seeds preferably at the end of August in autumn, water sprinkling, and coverage of the ryegrass seeds with soil having a thickness of 1-2 cm for germination; and 3, ryegrass management: cutting of the ryegrass by using a grass chopper or a reaping hook with 5-8 cm stubbles left when the ryegrass grows to 40 +/- 10 cm. The method can effectively inhibit grape root floating to ensure the quality of fruits and plants. The method is suitable for being used as a grape vine growing method for inhibiting grape root floating.

Description

technical field [0001] The invention proposes a viticulture technique in the biological field, specifically a cultivation method for planting ryegrass with tree trays to suppress the floating of grape roots. Background technique [0002] Up to now, my country's grape cultivation area has exceeded 12 million mu, of which the cultivation area and output of table grapes rank first in the world. In order to reduce the supply pressure of fresh water resources and improve water use efficiency, efficient water-saving technologies such as drip irrigation have become the first choice for grape irrigation. [0003] However, after adopting drip irrigation technology, the problem of grape root system floating becomes more and more serious, which seriously affects the growth and development of grape root system and its resistance to stress, such as cold resistance, which in turn affects the yield and fruit quality of grapes. [0004] Therefore, urgently need to propose a kind of method ...
