Management method for high-density early-yield cultivation of cherries in facility cultivation

Abstract

The invention discloses a facility cultivation cherry high-density early-yield management method, which comprises the following steps of container selection and substrate cultivation, nursery stock planting, management after planting and before germination, management in a germination period, management in a new tip period, management in a new tip stopping period, management in tree body structure parameters after leaf falling and management in a dormancy period. Starting management from temperature rise to germination, management from a germination stage to a flowering stage, and management from the flowering stage to a mature stage. According to the method, one-year-old sweet cherry seedlings are planted in a facility container in a high-density mode, and after 18-month cultivation management, the yield of a single plant is 0.8-1.2 kg, and the yield per mu is 667-1000 kg; the method has the characteristics of early forming, early fruiting, early high yield and the like, and an intensive, high-yield and efficient method is provided for industrial development of the facility sweet cherries.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a management method for high-density, early and high-yield cherry cultivation in facilities. Background technique [0002] At present, the protected cultivation of sweet cherry mainly adopts two methods of transplanting large trees in the full fruit period or building facilities on the spot in the cherry orchard in the full fruit period. Shandong, Liaoning, Shaanxi and other regions widely adopt the cultivation density of 2.5-3.5 meters between plants and 3.5-4.5 meters between rows. Common sweet cherry tree shapes include free spindle, small crown sparse layer and Spanish arbuscular. [0003] Existing cultivation techniques have high requirements on the quality of large sweet cherry trees in the full fruit stage, and it takes manpower to select and purchase such large trees, and long-distance transportation is required. During transportation, problems such as root system d...

Problems solved by technology

[0003] Existing cultivation techniques have high requirements on the quality of large sweet cherry trees in the full fruit stage, and it takes manpower to select and purchase such large trees, and long-distance transportation is required. During transportation, problems such as root system damage and branch injury often occur. In order to improve the survival rate of transplanting, a large number of thinning and pruning of flower buds is required, and the yield per mu of sweet cherry in the year of transplanting large trees needs to be controlled at 200-300 kg, which has a great impact on the early economic benefits of facility cultivation of sweet cherry
