Problems solved by technology

At present, the production of broccoli in Jiangsu is mainly in autumn and winter, and the market period is from late October to March of the next year. The rest of the time needs to be imported from other places such as Fujian or Gansu. Greenhouse planting is used to adjust the harvest time of flower bulbs. This planting method not only tastes bad, but is also prone to diseases during growth, and the yield is low.

Embodiment 1

[0021] Present embodiment cultivates broccoli according to the following steps:

[0022] (1) To build a simple greenhouse, choose a plot with high dryness, cool ventilation, good drainage, loose soil and fertile soil to build a greenhouse. Silver-gray sunshade nets and insect-proof nets are installed, and the whole shed is covered by insect-proof nets.

[0023] (2) Seeds were planted on August 12 (February 3 of that year was the Spring Festival). Seedlings were raised in 72-hole trays (PVC material). The trays were built with special nutrient soil for vegetables. The surface of the nutrient soil was 1 cm from the surface of the tray. Sow 3 to 4 seeds in the center of the hole. After all the seeds are sown, evenly spread a layer of nutrient soil, pour enough water, and cover the surface with a newspaper to moisturize.

[0024] (3) Management at the seedling stage: Seedlings emerge 3 days after sowing, remove the cover in time to allow the seedlings to fully see the sun, cover...

Embodiment 2

[0036] The present embodiment cultivates broccoli according to the following steps:

[0037] (1) To build a simple greenhouse, choose a plot with high dryness, cool ventilation, good drainage, loose soil and fertile soil to build a greenhouse. Silver-gray sunshade nets and insect-proof nets are installed, and the whole shed is covered by insect-proof nets.

[0038] (2) Sowing, sowing on August 3 (January 23 of that year is the Spring Festival), using 72-hole plug trays (PVC material) for seedling cultivation, and vegetable-specific nutrient soil for seedling cultivation.

[0039] (3) Seedling stage management: Seedlings emerge 2 days after sowing, remove the cover on sunny days to allow the seedlings to fully see the light, and cover the sunshade net when the temperature outside the shed is higher than 30°C at noon. Remove the sunshade net on cloudy days to keep the soil moist at the seedling stage, and cover the greenhouse with a film on rainy days. When the seedlings grow t...

Abstract

The invention relates to a method for cultivating broccoli in a greenhouse at high yield and high efficiency. The method comprises the steps of: preparing a seedling bed; implementing plug seedling in tray; implementing seedling management; preparing a land and applying a fertilizer; planting; implementing field management; preventing and controlling diseases and insect damages; adjusting temperature and humidity; reasonably closing or opening front and the back films of the greenhouse, a small arched shed thin film and two front doors of the greenhouse according to data of the temperature and the humidity in the greenhouse as well as weather conditions during the early budding period of the broccoli; and harvesting, and the like. The method has the beneficial effects that the harvesting period of the broccoli can be manually controlled by utilizing the sensitivity of buds in a developmental period to the temperature, so that the broccoli can be sold in the market around the Spring Festival, so that a high economic benefit can be obtained; simultaneously, the quality of the broccoli is improved and the production value per mu is high; and standardized pollution-free greenhouse cultivation is realized.

Description

technical field [0001] The invention relates to a cultivation method of broccoli, in particular to a high-yield and high-efficiency cultivation method of broccoli in a greenhouse, and belongs to the technical field of plant cultivation.
