Cultivating method for postponing sprout and maturity stage of grape

A cultivation method and grape technology, which is applied in the field of cultivation to delay the ripening of grapes, can solve the problems that the fruit cannot meet the AA-level green food standard, the procedures for heat preservation are complicated, and the tree is easy to be frostbitten, so as to reduce production risks and improve utilization. Rate and comprehensive benefits, easy to promote the effect

Problems solved by technology

Its disadvantages are: 1. The quality of the secondary fruit is relatively poor; 2. The use of exogenous hormones causes the produced fruit to fail to meet the AA-level green food standard; In case of low temperature, the tree body is easy to be frostbitten; 4. In areas with high temperature in early spring, the effect of delaying the harvest period is poor and the benefit is low

Embodiment Construction

[0007] The embodiment of the present invention is as follows: before germination in spring, the grape seedlings are planted in a large nutrient bowl, and the specifications of the nutrient bowl are: the diameter of the upper opening is 0.4m, and the height is 0.4m. Put the prepared nutrient soil into the nutrient bowl twice, the first time fill it to 1 / 3 of the height of the bowl, and arrange the nutrient soil into a "steamed bun shape" with a high middle and low surroundings, and compact it. Select first-grade grafted seedlings of good fresh food varieties such as Red Globe, Suike, and Cresen, properly trim the root system of the seedlings and fully spread them out, and place them on the nutrient soil in the nutrient bowl. The seedlings should be compacted until they are full, but should be 4-5cm lower than the upper edge of the nutrient pot to facilitate watering. Dig planting ditches in the field at a row spacing of 1-2m. The width and depth of the ditches are 0.4m each. T...

Abstract

The invention discloses a cultivation method for postponing sprout and maturity stages of grapes, which is one of grape postponing cultivation methods and aims at postponing the sprout of the grapes and then postponing a maturity picking stage, thus realizing the supply market of picking fresh grape in winter. The technical scheme of the invention comprises four parts: nutrition pot big seedling cultivation, low temperature refrigeration, open field temporary planting and greenhouse temporary planting. In spring, grape seedlings are planted in a big nutrition pot and put in a dug trench according to certain row spacing; the big seedling cultivation stage of the nutrition pot is finished by field management measures such as shaping, trimming and fertilizing and the like; after winter trim is finished, the nutrition port is dig out and moved into a low-temperature facility and refrigerated in the low temperature; in may of next year, the nutrition pot is shifted out of the lower temperature facility so that grapes normally spout, bloom and fruit, thus fining the open field temporary planting; before first frost arrives, the nutrition pot is shifted into a greenhouse, carefully managed till fruits ripens, thus finishing the complete process.

Description

technical field [0001] The invention relates to a delayed cultivation method for grapes, in particular to a cultivation method for delaying the ripening period of grapes. Background technique [0002] At present, the delayed cultivation of grapes mainly adopts methods such as selecting late-maturing varieties, selecting and retaining secondary fruits, spraying plant growth regulators, and covering the day and night in spring to delay the ripening and harvesting period of grapes. Its disadvantages are: 1. The quality of the secondary fruit is relatively poor; 2. The use of exogenous hormones causes the produced fruit to fail to meet the AA-level green food standard; In case of low temperature, the tree body is easy to be frostbitten; 4. In areas with high temperature in early spring, the effect of delaying the harvest period is poor and the benefit is low. Contents of the invention [0003] The invention provides a simple and easy delayed cultivation method for grapes, whi...
