Culture method for promoting early-maturing of grapes in cold tent

Abstract

The invention discloses a culture method for promoting early-maturing of grapes in a cold tent. The culture method for promoting early-maturing of the grapes in the cold tent comprises the following steps: (1) selecting a garden site: suitably selecting fertile loose sandy loam soil and light loam soil with deep soil layers and pH values of 5.5-7; (2) designing the cold tent: designing the cold tent according to the tent body span of 6-10 m and the height of 2.5-3.5 m, adopting drip-proof films with high transmittance to guarantee high transmittance of the cold tent, elevating the temperaturein the tent in early spring, replacing the tent films every 2-4 years, and conducting multi-layer tent film treatment; (3) setting a planting frame form: adopting an espalier frame, single-trunk double-arm shaping and hedge-shaped canopies; and (4) setting the planting density: adopting a broad-row dense culture mode with planting spacing of 0.8 meter*2.0 meter and a south-north row direction. According to the culture method for promoting early-maturing of the grapes in the cold tent, a structure of 3-4 layers of films is adopted for a tent body, thus the heat-retaining property is improved, safe overwintering is guaranteed, water bags are placed on two sides of the cold tent, by means of drop irrigation with water in the water bags, the ground temperature can be elevated, a utilization rate of moisture is increased, enough nutrients are provided for germination of the grapes, the maturing time and the time to market are advanced, and by placing candles or pans with fully-burnt charcoal in the cold tent, a cold spell in later spring can be effectively resisted.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for early cultivation of grapes in a cold shed. Background technique [0002] Grape is a woody vine of the genus Vitis vinifera, with cylindrical branchlets, longitudinal ribs, glabrous or sparsely pilose, oval leaves, dense or scattered panicles, well-developed base branches, spherical or oval fruit, flowering period April-May, fruiting period August-September. Grapes are one of the oldest fruit tree species in the world. Plant fossils of grapes were found in Tertiary strata, indicating that they were all over Europe, Asia and Greenland at that time. Grapes originated in western Asia and are cultivated all over the world. About 95% are concentrated in the northern hemisphere. Grapes are a famous fruit, eaten raw or made into raisins, and brewed. The leftovers after brewing can extract tartaric acid. Irrigation quotas are the basis for planning and desi...

Problems solved by technology

However, due to the lack of modern management techniques, the market purchase price is low, and the yield and quality are always low. Therefore, a cold shed to promote early cultivation method for grapes is proposed.
