Organic cauliflower planting mode

1. Disinfection of seeds

The first step in growing organic cauliflower is to disinfect the seeds. Seed disinfection can effectively prevent all kinds of diseases and insect pests of cauliflower.

2. Cultivate strong seedlings

Organic cauliflower can be cultivated in spring or autumn. In spring cultivation, sunny beds can be used to raise seedlings. Before the seedlings are unearthed, the seedling bed can not be ventilated. Only after a week of emergence can the seedlings be ventilated. During this period, it is necessary to maintain a suitable temperature in the morning and evening and carry out seedling training. For autumn cultivation, the seedlings should be planted in a rain-proof shading shed and keep the seedling field moist. At the same time, it is necessary to disinfect the soil and seedbed in a certain time to prevent the occurrence of diseases and insect pests.

3. Land preparation and planting

When the seedlings grow to a certain extent, it is necessary to prepare and plant the seedlings, apply a certain amount of organic fertilizer to the planting site, the width of the border is fixed, plant two rows of cauliflower in each row, and choose different plant spacing according to different varieties maturing sooner or later. Generally speaking, the planting density in autumn is lower than that in spring.

4. Late cultivation.

In the later stage, water and fertilizer management and side branches were removed, and pest control was carried out regularly, so that organic cauliflower could grow more healthily.

Soil preparation and colonization of organic cauliflower

In the land to grow organic cauliflower, 5000 kg of rotten organic fertilizer is applied per mu, and the land is deeply ploughed and raked flat for border use, with a width of 140cm to 150cm and two rows of cauliflower on each border.

The planting spacing of flowers and materials varies with different varieties. The spacing of each plant is about 30 cm for early-maturing varieties, 40-45 cm for middle-maturing varieties and 50-60 cm for late-maturing varieties. At the same time, the customized density varies with different seasons. generally speaking, the density is small in autumn and high in spring.

Temperature management

Organic cauliflower should keep warm during the period from planting to slow seedling. The daytime temperature should be 25 ℃, and the night temperature should be slightly lower, preferably between 15 and 20 ℃. During the leaf cluster growth period of cauliflower, the daytime temperature should be kept between 20 and 25 ℃, while the night temperature should be kept around 15 ℃, neither too high nor too low. In the period of flower head formation, organic cauliflower needs a cool climate, so it is better to keep the temperature between 21 ℃ in daytime and 10-15 ℃ at night.

Water and fertilizer management

The principle of water and fertilizer management after organic cauliflower planting is to promote seedlings in the early stage, to control water and fertilizer in the middle stage, and to attack buds in the later stage. Generally speaking, it only needs to be topdressing three times, the first time within a week to two weeks after planting, the second time about a month after planting, when the plant has more than a dozen true leaves, and the third time when the plant is budding. Topdressing 1000 kg of high-quality organic fertilizer per mu each time.

Moisturizing and pruning

The land for planting cauliflower should be kept moist, especially during the period of bulb hypertrophy, and the land should not be short of water. However, it should be noted that cauliflower is also afraid of waterlogging, so as long as it keeps the land moist during its growth, it should be drained in time when it is overwatered.

Cauliflower is easy to produce side branches, which should be removed before harvest. When most of the main balls grow to about 10 cm, leave a few side branches appropriately, but not too many. Always remove the dust from the film, keep it clean, improve the light transmittance, and ensure the normal growth of organic cauliflower.

Pest control

Pieris rapae and Plutella xylostella are common diseases and insect pests when growing organic cauliflower. Once found, Bacillus thuringiensis is used for timely control. If aphids appear, 1% soap can be used to control them. In addition, in order to reduce the occurrence of diseases and insect pests, the net room cultivation method can also be used for planting.

It is not easy to grow delicious and nutritious organic cauliflower. The editor now feels that he didn't eat cauliflower well in the past. I really feel ashamed to the people who grow cauliflower. After understanding the planting technology of organic cauliflower, let's take a look at its nutritional value.

The difference between organic cauliflower and cauliflower

Organic cauliflower and cauliflower are both cauliflower and cruciferous vegetables. But there are differences between them. The bulbs of organic cauliflower are scattered and evacuated, while the bulbs of cauliflower are held together more tightly. Also, the stem of organic cauliflower is green, while the stem of cauliflower is white. Organic cauliflower is yellow, and cauliflower is milky white. In taste, organic cauliflower is more refreshing and crisp.

That's all for today's introduction. I believe you have learned more about the cultivation of organic cauliflower. Through our own efforts and effective planting techniques, we can also grow big, good, natural and healthy organic cauliflower.
