How do you want to make high-yield cauliflower cultivation? Recently, many cauliflower growers have consulted similar questions. Today, Hui Nongwang Xiaobian talked with you about the high yield of cauliflower, which should be cultivated. Cauliflower prefers a cool climate, avoids high temperature and drought environment, and is relatively easy to cultivate. It is one of the varieties of vegetables suitable for planting in the free land after the harvest of late rice.
1 cultivation season
The cauliflower cultivation season is generally selected in spring and autumn, and spring is generally planted between December and January of the following year, and harvested from late April to early May of the following year. Autumn cultivation is generally carried out from mid-July to September, and the harvest is harvested from early October to February.
2 sowing seedlings
The sowing and seedling cultivation of cauliflower is the key to obtaining high yield. It is not good to plant seeds too early or to plant too late. The seedbed should be selected with high ground and well-drained loose soil. After emergence, the small arch shed is covered with a shade net to cover the cover and cool down. Generally, it is covered from 8:00 am to 5:00 pm, and the rest of the time is removed. Then the cover time is gradually reduced, and the 3-4 days before the planting is removed to remove the seedlings to prevent the child from growing. In case of heavy rain, it is necessary to cover the film in the seedbed shed to avoid rain and fall. When the seedlings are 2-3 leaves, the planting is carried out. During the seedling bed, it is necessary to control the cabbage budworm and the twill scorpion, and it can be used 1500 times and the insecticidal 1500. Double (10mm to 30 kg of water) prevention.
3 Site preparation
Generally, the base fertilizer is applied to the ground before planting, and 1500 kg of fertilized organic fertilizer and 20 kg of compound fertilizer or 20 kg of superphosphate, 20 kg of compound fertilizer and 10 kg of potassium chloride, and 1 kg of borax may be applied to the area lacking boron fertilizer. Should be applied in moderation.
When the seedling age is 5-6 days, the plants are planted in 5-6 true leaves. The planting method is 1.3 ft 2 rows or 2 m 畦 wide (Liangou) 3 rows, and the plant spacing is 45-50 cm. The density of the acre is 1800-2000. The factory requires that the density of the small flower ball can be increased appropriately, with 2000-2300 plants per mu. After planting, the roots are stagnant with clear water, and the plants are lightly applied after living, and about 2.5 kg of urea is applied per mu.
In the case of long-term arid climate during planting, it is better to keep the seedlings live without planting the land. When the planting is done, a small amount of superphosphate is applied in the hole, and the amount of the acre is about 20kg. 25kg.
4 Grasp the field management
The broccoli requires warmth, and the soil should be kept moist during the slow seedling period. Especially in the vigorous growth period of the leaf cluster and the flower bud development period, sufficient water should be ensured. In the dry year, it should be watered in time, usually at a 4-day interval; Rainy years should also be drained in time to prevent water accumulation in the field.
In the early stage of growth, the seedlings are inferior. It is advisable to apply topdressing lightly. Generally, 5 kg of urea is applied per acre. The bud period and the flower bulb hypertrophy period are based on the growth conditions. It is not suitable to apply nitrogen fertilizer. The application of compound fertilizer is better. The amount of mu is 10-15 kg. . The broccoli plants are tall, combined with fertilization before the closure of the line for timely weeding and weeding, and soil cultivation to prevent lodging; the germination of broccoli is strong, and before the main flower ball is expanded, combined with cultivating and weeding, the lateral branches are removed, and the soil cannot be too high, so as to avoid root suffocation. Brown rot.
5 pest control
The main diseases are seedling stage blight and late downy mildew and black rot, which can be controlled by 75% chlorothalonil 1000 times solution or 100-120 ml/L agricultural streptomycin. Insect pests mainly include cabbage caterpillars, aphids, diamondback moths and tick-faced nightingales, which can be controlled by 2.5% enemy killing 2000 times, suppression of Taibao 1500 times and insecticidal 1500 times (10mm to water 30 kg).
6 harvesting
According to the market and processing plants, the demand for different specifications of broccoli is harvested in time. The small flower ball is generally harvested in the diameter of 12-14cm flower ball and 150g in single ball. The large flower ball is generally harvested from 400g, and the largest flower ball can reach 500. - 600g.
7 Quality standards for broccoli
7.1 freshness
After the raw materials are harvested, they should be delivered to the factory in time. The raw materials must be fresh, and there should be no dryness or discoloration.
7.2 color
Emerald green, the color is more consistent, can not have different color buds. A small number of purple spots are allowed.
7.3 flavor
It has the taste and fragrance of broccoli and must not have odor.
7.4 Organizational form
The tissue is tender, the flower buds are tight, the buds are not open, and the shape is complete. No pests and diseases, no flowers and yellowing.
7.5 variety specifications
Use green belt and other varieties. Its variety specifications should meet the requirements of the production or customer.
7.6 foreign body
There can be no metal, insects, bamboo chips, etc.
The above is the main point of high-yield planting techniques of cauliflower. Farmers who need it can collect first, and more cauliflower cultivation techniques can continue to pay attention to Huinong.
The generic name of VTM Virus Sampling Tube is a single-use virus sampling tube, which is generally used for the detection and sampling of infectious pathogenic microorganisms in disease control departments and clinical departments. It is suitable for detection and sampling of influenza viruses (including general influenza, highly pathogenic viruses, H1N1 influenza virus, etc.), hand, foot and mouth virus, new coronavirus, measles and rubella and other types of viruses. VTM virus sampling tube can also be used for detection and sampling of Mycoplasma, Chlamydia and Ureaplasma urealyticum.
The virus and related samples in the VTM virus sampling tube should be stored and transported within 48 hours in a refrigerated state (2-8°C). Viruses and related samples can be stored for a long time in -80℃ environment or liquid nitrogen environment. The virus can maintain the activity of the virus in a lower temperature range, reduce the speed of virus decomposition, and improve the positive rate of virus isolation.
The VTM virus sampling tube is generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for different Partial sampling person. Moreover, the flocking swab is designed with a breaking point that conforms to the length of the sampling tube and the natural orifice of the human body, which is not only convenient for sampling but also convenient for transportation of the specimen.
