Caixin, also known as cauliflower and vegetable moss, is one of the specialty vegetables in Guangdong. It is known as the “top vegetable†and is rich in variety and adaptability. It can be grown all year round. Its high-quality and high-yielding cultivation techniques are described as follows: First, choose the type of early-maturing varieties of ripening seeds: 4919, 4920, and the whole year's vegetable heart; medium-maturing types have 60 days of special green, Baoqing 60 days, and Lvbao 70 Days, etc.; late-maturing type has late heart 2, 80 days heart, March heart and so on. Second, the soil from the site preparation, deep plowing, whitening, full base fertilizer. Basal fertilizer generally applies 1000-1500 kg of organic fertilizer per mu, 5-10 kg of potassium chloride, or 750 kg of chicken gizzard, and 20 kg of compound fertilizer. Wow is generally 1.6-1.7 meters wide and 20-30 centimeters high. It is turtle-shaped. Third, timely planting early maturing varieties suitable for cultivation from April to August, medium-maturing varieties suitable for cultivation from September to October, late-maturing varieties suitable for 11-year-on-year cultivation in March. Early and mid-maturing varieties are mainly broadcasted; late-maturing varieties are mainly transplanted. Early and mid-maturing varieties should not be sowed late, otherwise it will lead to rapid budding bolting, small vegetable heart, low yield, or even failure; late maturing varieties can not be early sowing, otherwise lead to late bolting, bad quality of cabbage moss. Winter or spring should be planted at the end of the cold wave, and summer and autumn should avoid sowing in rainy, stormy and typhoon rainy weather. Generally about 0.5 kg sowing per acre. Fourth, field management 1, seedlings Dingmiao: Direct-growing cabbage heart began at the beginning of the cotyledon, seedlings 1-2 times; transplanting cabbage seedlings in the seedlings when combined with 3 seedlings for seedlings Dingmiao. Dingling plant spacing is generally 1013 cm for early maturing varieties, 1720 cm for mid-maturing varieties and 2023 cm for late-maturing varieties. 2, a reasonable fertilization: Yi Qin Shi, early application, thin application, top dressing is suitable for quick-improvement complete fat. The cabbage leaves are top-dressed in the first time when the true leaves are unfolded, and 3-4 kilograms of fertilized water or urea is applied per acre. When the three true leaves are combined, the seedlings are chased once. After that, 5-10 kg of urea and 10-20 kg of compound fertilizer can be applied every 5-7 days. Apply heavy fertilizer at the bud, apply 15-25 kg compound fertilizer per mu. After harvesting the main moss to continue harvesting the side moss, most plants should collect the main moss and apply concentrated fertilizer to promote the growth of the cabbage. 3, water management: keep the soil moist throughout the growth period. Sunny morning and evening summer rain water; rainy days pay attention to drainage, to prevent flood area water; before winter, drought, irrigation antifreeze, that irrigation is row, not flood irrigation. 5. The timely harvesting and harvesting of cabbages takes the harvest period as the standard of harvesting. Most of the early-maturing varieties only harvest the main moss. In other varieties, it is generally possible to continue collecting the side moss after harvesting the main moss. On the side of the harvested moss, the main moss was cut at the base of the plant from 2-3 leaves. The two sides of the axillary buds were used to germinate the side of the moss, leaving too many leaves, but the side mosses were numerous but slender and of low quality. After the harvest period is reached, if the temperature is low, it may be 2-3 days late. If the temperature is high, it should be harvested in time. VI. Pest and disease control 1. Disease prevention and control: Epidemic disease, downy mildew can be used to prevent and treat 600 times of epidemic-mild spirit, Rhodospirillum Mn-Zn. Soft rot and black rot can be treated with 20% of Longkei 600 times and 72% of agricultural streptomycin 3,000 times. Viral disease strictly prevents the infection of aphids. After the disease can be used virus A, phytosanitary spirit, virus and other leaf surface control. Anthrax can be controlled by 75% chlorothalonil and 70% thiophanate-methyl 800 times. Black spot, white spot disease can be controlled by 1500 times 10% or 40% polysulfide suspension. 2. Pest control: Aphids can be sprayed 1500 times with 10% imidacloprid. The cabbage caterpillar and diamondback moth can be sprayed at a low age of larvae 500 times with Bacillus thuringiensis or 1500 times with high chloroplasts. Yellow striped jumpers can be used 800 times for 48% or 600 times for a shot.
