水果苤蓝春大棚3膜覆盖高效栽培技术

High-efficiency Cultivation Technologies of Fruit-type Kohlrabi with Three Layers of Film Covering in Spring Greenhouse

立足蔬菜生产一线,以新品种选育、栽培形式改良、示范推广为技术节点,探索总结了1套水果苤蓝春大棚3膜覆盖高产高效栽培技术,通过在大棚内加盖第2层膜和地膜,与外棚膜一起形成3膜覆盖保温结构,为苤蓝提供了适宜的生长环境,与传统露地、地膜覆盖栽培相比,定植时间从3月中旬、3月下旬提前到2月上中旬,667 m^(2)产量4 000 kg以上,产值9 600元以上,实现了水果苤蓝早种早收,高产高效的目标。

Based on the forefront of vegetable production and taking the breeding of new cultivars,improvement of cultivation forms, demonstration and popularization as the technical keys, a set of highyield and high-efficiency cultivation technology of fruit-type kohlrabi in spring greenhouse with three layers of film covering was explored and summarized. By adding the 2nd layer of film and ground film inside the greenhouse, together with the outer greenhouse film to form a three layers of film covering insulation structure, it provided a suitable growing environment for kohlrabi. Compared with the traditional open field and film-covered cultivation, the planting time was advanced from mid-March and late March to the first half of February, and the yield was more than 4 000 kg per 667 m^(2) and the output value was more than 9 600 yuan per 667 m^(2), which realized the goal of early planting and early harvesting of fruit-type kohlrabi with high yield and high efficiency.
