Planting techniques of organic cauliflower

Land preparation and planting

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.

How to grow organic vegetables? Organic vegetable planting technology, organic vegetable planting method

Introduction: with the improvement of people's living standards, people have higher and higher requirements for food security, and even vegetables have begun to pursue organic cultivation, so how to grow organic vegetables? The following is the first agricultural economic editor to introduce you to the method of growing organic vegetables.

The key points of organic vegetable planting techniques are as follows:

1. Variety selection

Organic vegetable seeds and seedlings should be used. Select vegetable species and varieties that adapt to local soil and climate characteristics and are resistant to diseases and insect pests, and prohibit the use of coated seeds and genetically modified seeds.

2. Seed treatment technology.

Seed disinfection can use natural substance disinfection and seed soaking technology of warm soup. Soak lh with potassium permanganate 300x solution for 2h, wood vinegar 200x solution for 3h, lime water 100x solution for 1h or copper sulfate 100x solution for natural substance disinfection, then soak seeds in warm soup for 4h.

3. Disinfection of soil and shed

Physical or natural substances are selected for soil disinfection. Soil disinfection substances can be treated with 3Mel 5-degree stone-sulfur mixture, crystal stone-sulfur mixture, quicklime 37.5kg/hm2, potassium permanganate 100-fold solution or wood vinegar 50-fold solution. The seedbed can be disinfected by spraying the seedbed with 50 times of wood vinegar 5 days before sowing, covering the mulch or plastic film, or mixing with 0.5kg/m2 and sealing with plastic film.

4. Crop rotation, crop rotation and rural cleaning

Rotation was conducted with at least three crops, including legumes or green manure. In areas where only one crop of vegetables can be grown a year, rotation of two crops, including legumes, is allowed. After harvest, clean and clean thoroughly, and transport all the disabled bodies out of the base for destruction or deep burial.

5. Fertilizer application technology of organic vegetables.

Allow the use of organic fertilizers (including faeces and residues of animals and plants, plant compost, green manure, plant ash and cake fertilizer, etc.), organically certified special organic fertilizers and some microbial fertilizers) and some minerals (including potassium rock powder, phosphate rock powder and calcium chloride). Generally, organic fertilizer 45-60t/hm2 was applied at the bottom, and organic special fertilizer 1500kg/hm2 was applied after topdressing. 80% of the total amount of fertilizer is used as base fertilizer, and the fertilizer is evenly mixed into the tillage layer combined with soil preparation to facilitate root absorption. At the same time, we should skillfully apply topdressing. Topdressing can be used for vegetables with high planting density and shallow roots; for vegetables with large row spacing and concentrated roots, topdressing can be used for vegetables with large row spacing; for vegetables with large row spacing, hole topdressing can be used.

6. control techniques of diseases, insect pests and weeds in organic vegetables

The use of all chemical synthetic pesticides and products produced by genetic engineering technology are prohibited in the production process. Adhere to the principle of "giving priority to prevention and combining prevention with prevention". Through the selection of disease-resistant varieties, high-temperature disinfection, reasonable fertilizer and water management, rotation, diversified intercropping, protection of natural enemies and other agricultural and physical measures to comprehensively control diseases, insect pests and weeds.

7. Organic vegetables should be harvested at the right time

Do not harvest in continuous rainy days, because if the photosynthesis of vegetables is not enough, there will be residual nitrate. In addition, do not apply fertilizer a few days before harvest. When harvesting, the roots can be kept, and some vegetables will grow new seedlings, otherwise, stir the soil. After a few times, your soil will become very fertile.

Organic vegetable planting technology and planting base

Content Abstract: with the current attention to food safety, the requirement of no pollution and no addition of chemical elements has become an important standard of daily diet, and therefore, there is the existence of organic vegetables, and now the market reference, organic vegetables will gradually occupy the home market, this article introduces to you, organic vegetable planting technology and planting base.

[organic vegetable planting technology and planting base]

Noun explanation: organic vegetables refer to edible vegetables that are forbidden to use any pesticides or chemical accelerants in the whole normal process. Food contains high green standards, pure nutrition, in line with the concept of natural ecology, and has a strong effect on health preservation.

Organic vegetable planting base

Organic vegetable planting base has been oriented to the development of the whole country, and now the main organic vegetable planting bases are Beijing, Shenzhen, Henan, Zhejiang, degree, inflatable, Shenyang and so on.

Beijing organic vegetable planting base is the largest and most large-scale organic vegetable base in the country, with an area of more than 500 mu, which is mainly represented by rainbow rain organic vegetables and happy farm organic vegetable bases. it can not only provide the market demand for the whole city, but also distribute for the surrounding provinces and cities, and even begin to sell on the network, and the distribution system is perfect.

Planting techniques of organic vegetables

1. Variety selection: in the cultivation of organic vegetables, you can choose two kinds of fruit seeds and seedlings, mainly non-transgenic seeds, not any kind of transgenic seeds.

two。 Base selection: the selection of organic vegetable base should have certain rotation characteristics, and its soil and profile should meet the cultivation of at least three kinds of crops, and should be thoroughly cleaned before and after harvest.

3. Base preparation: before planting, the base should have greenhouse, light and heat, watering, ventilation and other conditions, and should create an environment suitable for the survival of vegetables.

4. Seed-carrying technology: the planting of organic vegetables can avoid planting, can choose to sow in one step, and can cooperate with grafting, seedling filling, close planting and other work in the later stage to adjust the seed-carrying defects.

Fertilizer selection of organic vegetables

The cultivation of organic vegetables, can not come into contact with any chemical fertilizer, can only choose organic fertilizer, green manure, secondly, you can also choose self-made mature fertilizer, human and animal manure, plant ash, cake manure and so on.

Before fertilization, preparation should be started two months in advance, and it can be diluted properly with water, and the purpose of fertilization can be achieved by watering. In the later stage, it can be covered with film and straw to wait for its fermentation, and the temperature should be controlled above 60 degrees Celsius. It can be maintained for one day, and the normal growth can be restored in the later stage.

The amount of fertilizer applied to organic vegetables is less than 4000 kg per mu and should not be less than 3000 kg. In the later stage of topdressing, the special fertilizer for organic vegetables is mainly selected, and the time of topdressing is at flowering stage.

Summary: this paper mainly introduces the planting technology of organic vegetables for you, as well as the main introduction of organic vegetable base. The cost of choosing to cultivate organic vegetables is high, and because of the limitation of planting only in the base, it is not suitable for indoor home cultivation.
