Cabbage, also known as cauliflower, the main edible parts of the flower stem and young leaves, is one of the characteristics of the consumer favorite vegetables. Vegetable heart sweet and savory, tender and nutritious, known as the "crown of vegetables". Vegetable heart of strong adaptability to the environment, fast growth, short growth period, can be cultivated throughout the year.

Requirements for planting environmental conditions

1. Temperature: the temperature requirements of the vegetable heart is not strict, the average temperature of 10-28 ℃, you can grow successfully. Under the same low-temperature conditions, early-maturing varieties of cabbage hearts are easy to pass through vernalization, while late-maturing varieties take longer to pass through vernalization. In actual planting, it is necessary to choose the right variety of vegetable hearts according to the local climatic conditions and planting season.

2. Light: the cabbage is a typical long sunshine plants. Sufficient light is favorable to vegetable heart.

3. Moisture: vegetable heart is neither drought-resistant nor flood-resistant, very strict requirements for moisture, must keep the soil moist, not waterlogged.

4. Soil: the cabbage heart is not strict on the soil requirements, you can plant the general fertility of the soil. Nitrogen is the main nutritional requirement of the plant, followed by potassium and phosphorus are the least.

5. Plot selection and land preparation: In order to have high yield, we need to choose loamy soil that is ventilated and transparent, flat and loose, easy to drain and irrigate, and rich in organic matter. Before formal planting, the field should be sufficiently dried, deep plowing, harrowing, ridging, drying and applying sufficient organic fertilizer before sowing. The height of the whole plot is about 30 centimeters and the width is 1.2 centimeters.

6. Reasonable and dense planting: when the first true leaves of the cabbage heart unfolded, the seed should be sown in time, and then sown 1-2 times. When planting 3-5 true leaves, we should sow in time. The specific cultivation density depends on the characteristics of the variety, the main planting 12 cm × 15 cm, the main planting 15 cm × 20 cm, we should timely check and fill in the gaps, and eliminate the poor quality seedlings.

7. Fertilizer management: In addition to applying enough base fertilizer, it is also necessary to follow up the fertilizer in time in order to apply thin and diligent fertilizer as early as possible. Vegetable heart seedlings, generally every 10-15 days fertilizer, fertilizer 8-10 kg per mu of high-quality three yuan compound fertilizer, fertilizer timely watering, to avoid fertilizer damage.

8. Watering management: vegetable heart plant water requirements are more stringent, must correctly grasp the watering method and frequency. Spray water once in the morning and evening on sunny days. After entering the hot weather, you can appropriately increase the frequency of watering. Before harvest, we must control the amount of watering so as not to affect the quality.

9. Timely harvesting: the optimal harvesting height of vegetable hearts is 20-25 centimeters. If harvested too early, the cabbage hearts are too tender and small, and the yield will be low. However, if harvested too late, the yield will be high, but the quality will be severely reduced.
