Scientific planting techniques of cauliflower

In daily life, many people like to eat cauliflower very much, because cauliflower is a simple production method, the taste can be soft but crisp, very delicious. Cauliflower, also known as cauliflower, is one of the very good vegetables to grow, so let's go with the editor to see the correct way to grow cauliflower.

Scientific planting techniques of cauliflower

1. Land selection and preparation: it is advisable to choose sandy loam with relatively fertile and well drained soil for planting, and the terrain should be sunny and flat. Cauliflower seeds are small, soil preparation must be meticulous at the same time to apply enough fertilizer, intensive cultivation, adequate basic fertilizer, water, so that soil moisture, strong, flat, soil free of diseases and insect pests.

2. Management after sowing: after sowing, spraying soil surface with 600 times liquid of new high fat film can preserve soil moisture and prevent evaporation, sun and drought resistance, heat preservation and freezing protection, soil layer hardening, suffocation and isolation of disease and insect sources, and improve seedling emergence rate.

3. Fertilization, watering, weeding, prevention of diseases and insect pests: watering is moist at any time, reasonable fertilization, weeding, spraying targeted pest prevention drugs and new high-fat film can be used at the same time, which can greatly improve the utilization rate of effective ingredients of pesticides and fertilizers. not afraid of sun exposure and evaporation, can adjust the absorption of water-saving, drought and rain prevention.

4. The product organ of cauliflower is a flower ball made from shortened flower branches, flower rachis and flower buds, which is not only a reproductive organ but also a nutrient storage organ. The shortened flower branch is in the period of rapid extension. Spraying vegetable Zhuangxinling can make the plant stem stout and the flower ball hypertrophy, at the same time, it can improve the ability to resist disasters, reduce the amount of pesticide and chemical fertilizer, and reduce the residual poison.

Planting conditions of cauliflower

Cauliflower has developed root system and strong regeneration ability, so it is suitable for seedling raising and transplanting. It is easy to suffer frost injury below 0 ℃, but it is difficult to form a flower ball above 25 ℃. The growth of foliage and bolting and flowering require warmth, and the optimum temperature is 20-25 ℃. The formation of the bouquet goes through the stage of vernalization at low temperature. The requirement of light condition is not strict, but the requirement of water content is relatively strict, which is neither waterlogging nor drought resistant. It has strong adaptability to soil, but the sandy loam with high organic matter and deep soil layer is the best. The suitable soil pH is 5.5-6.6. It has strong salt tolerance and can still grow normally in the soil with a salt content of 0.3% to 0.5%.

Characteristics of cauliflower

Cauliflower, also known as cauliflower, is a variety of cabbage. The common cauliflower is snow-white, while a few cauliflower is purplish red. In recent years, Europe and the United States have developed yellow or green cauliflower, such as Green Golden Queen, Green Lady and so on.

The cold and heat resistance of cauliflower is weaker than that of heading cabbage. It likes temperature and humid conditions and avoids high temperature and drying. The seedlings could tolerate temperatures of about 0 ℃ and 25 ℃, the optimum temperature for growth at rosette stage was 8 ℃-24 ℃, and the leaves were frozen at-1-- 2 ℃. The suitable temperature during the growing period was 8-20 ℃, and 13-18 ℃ was the best, the growth below 8 ℃ was slow, and the curd was frozen about 0 ℃. The cord was easy to be loosened above 20 ℃, and a few varieties could form it at the temperature above 20 ℃.

It is easy to grow cauliflower on fertile and loose soil with good drainage and water conservation. During the vegetative growth period, it is necessary to absorb a large amount of nitrogen nutrients, and the application of phosphorus and potassium fertilizer is beneficial to the formation and development of rosette, which is easy to occur black heart phenomenon when potassium deficiency. Boron deficiency, stem base cracking, serious bouquet is embroidered brown, the product has a bitter taste. When molybdenum is deficient, the plant is dwarfed, and the leaf is slender and whip-shaped, slightly twisted.

The temperature required for cauliflower bulb expansion is different from that required by vernalization stage. Usually, the winterness of mid-early maturity varieties is weak, the seedlings grow normally at higher temperature, and the flower heads are developed at lower temperature through vernalization stage at higher temperature. This kind of variety is suitable for cultivation in autumn. The middle and late maturing varieties have strong winterness, and through the vernalization stage at lower temperature, the flower bulb can develop and hypertrophy at higher temperature, which is suitable for cultivation in spring.

Edible value of cauliflower

It has anti-cancer and anti-cancer effect. Among the many fruits and vegetables, broccoli and Chinese cabbage have the best anti-cancer effect, according to the American Cancer Society. Cauliflower contains isothiocyanate compounds and trace elements, which has the effect of antioxidation. Long-term consumption of cauliflower can reduce the incidence of cancer such as rectal cancer, breast cancer and gastric cancer. Contains flavonoids, which can protect the cardiovascular system. Flavonoids can prevent infection, is the best vascular cleanser, can prevent cholesterol oxidation, prevent platelets from clotting, can reduce thrombosis, thus reducing the risk of heart disease and stroke, and low mortality from coronary heart disease. Cauliflower is one of the vegetables with the most flavonoids.

Rich in vitamin k. Prevent internal bleeding and hemorrhoids, reduce massive bleeding in the physiological period, and promote normal blood coagulation. Some people are not easy to get well from small collisions and injuries because of the lack of vitamin K. Cauliflower is rich in vitamin K that ordinary vegetables do not have.

Through the above, I believe you have a more in-depth understanding of the planting method of cauliflower. In fact, the planting method of cauliflower is very simple. Under certain conditions, you can plant a little broccoli. Because cauliflower is very nutritious and delicious, it is loved by everyone.
