Broccoli is rich in nutrients, in recent years, the market sales are good, farmers are willing to plant strong, with the development of facilities and vegetable technology, greenhouse cultivation of broccoli is also in full swing, today on the greenhouse broccoli cultivation technology to discuss with you:

One, the right period of seeding

Broccoli like cool environment, fall and winter cultivation of varieties in the July and August sowing, early spring cultivation of varieties in October and November sowing, according to the current market demand while harvesting earlier to get a bigger economic benefit. The varieties cultivated in fall and winter are sown in July and August, and the varieties cultivated in early spring are sown in October and November. When sowing in greenhouses, according to the current market demand, we should harvest the broccoli in advance while ensuring the yield to obtain greater economic benefits.

Second, variety selection

The greenhouse cultivation of broccoli, in order to ensure the yield, at the same time, to choose suitable for the soil conditions of the region, high-quality high-yield varieties, varieties need to have a strong resistance to diseases and pests and high-yield advantages, early-maturing varieties of green treasure, Li Green, etc., and medium-maturing varieties of green show, Yan Xiuxiu, etc., the benefits are good.

Three, seedbed

General seedbed width control in about 100 cm, the thickness to maintain about 10 cm, the nutrient bowl to the field soil and rotting organic fertilizer 3:2 ratio mix, mixing to add the right amount of calcium phosphate, especially cold winter, the bottom of the seedbed paved with hot wire.

Four, seed treatment

Selected seeds, soaked in warm water at 33 ℃ for 15 minutes, and then washed with water into the germination stage, you can also use carbendazim powder mixed with water to soak, and then rinsed with water to germinate, you can use gauze wrapped in a package, placed in 30 ℃ conditions to germinate, and when the dew white more than half of the number of times, then you can sow the seeds.

Five, sowing

Sowing time is best chosen in the morning on a clear day, to avoid excessive light sowing, about 50 grams of seed per acre, which is based on the sowing area and soil conditions to determine their own, in order to ensure that the rate of germination, to ensure that the sowing area has a sufficient supply of water, for this reason, the need for irrigation before sowing operations, the sowing area of the soil watered through, and then evenly sown in the seedbed of sprouting seeds, and finally covered with 0.8 cm or so, and the seeds can be sown in the seedbed. Finally covered with about 0.8 cm of nutrient soil, after the emergence of seedlings, can be used to carbendazim powder and fine soil mixture evenly spread on the seedbed, to avoid pests harming broccoli.

Sixth, planting

Pre-planting needs to be sterilized on the greenhouse, available 95% green Hen 1 soil disinfection, 5000 pounds of rotted organic fertilizer per acre, 100 pounds of ternary composite fertilizer or so, the whole ground to do the ridge, the general ridge height of 15 centimeters, the ditch width of 40 centimeters, the width of the ridge of 80 centimeters, the autumn and winter planting in late August, planting in the early spring in late October, the summer cultivation, the planting of the latter part of July, per acre of about 2760 plants. About 2760 plants.

Seven, field management

The need for timely control of greenhouse temperature and humidity, the daytime greenhouse temperature to maintain 25 ~ 30 ℃, the night temperature of 12 ~ 17 ℃, high temperatures in the summer, the available shade nets to reduce the temperature of the greenhouse, the temperature is low in the fall, the available reflective film to increase the light, the right time to catch up with the fertilizer, watering in a timely manner, to ensure that the growth of broccoli needs.

Eight, pest management

The greenhouse cultivation field should be reasonable crop rotation, the best implementation of drought and water crop rotation, the use of drugs to prevent and control broccoli moths, aphids, etc., and at the same time, for the black rot, anthracnose, viral diseases should be timely prevention and treatment. When the flower bulb grows to about 0.5 kg, the diameter is about 12~18 cm, the color is deep green, and the flower bulb is tightly packed, then it can be harvested.

In summary, broccoli is rich in nutrients, can provide a variety of nutrients for the human body, greenhouse cultivation should be the right time to sow seeds, select varieties, cultivate strong seedlings, timely planting, control of greenhouse temperature and humidity, fertilizer management, and pests and diseases to do a good job in the operation, in order to get the maximum economic benefits.
