The cultivation of organic cauliflower in the greenhouse in winter can not only regulate and make up for the off-season vegetables, but also greatly improve the land utilization rate and make the organic cauliflower gain higher benefits. Here is a description of organic cauliflower planting measures:
Organic cauliflower has poor tolerance to sorghum. Planting cauliflower in rainy areas and high groundwater conditions should adopt technical measures of deep ditch and high compartment to facilitate drainage. This is the key to the success of cultivating cauliflower. Cauliflower should also be avoided in continuous cropping. For the first time, melons, solanaceous fruits and legumes should be used. Fertile loam and clay loam should be selected for field cultivation. Re-application of base fertilizer, 3,000 kg of fermented farmyard manure, 50 kg of phosphate fertilizer, 25 kg of potassium fertilizer, 25 kg of urea, and even tillage, tilling. The autumn cauliflower can be opened in 4 meters, the early maturing varieties are planted in 8 rows, and the late-maturing varieties are planted in 6 rows.
Organic cauliflower planting should be carried out on cloudy or sunny afternoons, after watering. Transplanting should not be too deep, and the nutrient cup soil should be parallel or slightly higher than the face soil, and the root water should be applied. If you encounter long-term dry soil, it is best to fill the tank with water before transplanting, and wet the surface to help reduce the soil temperature.
After cultivating the seedlings, cultivate 1 time and water. If there is too much rain and the humidity of the field is too high, it is necessary to carry out more cultivating to keep the roots dry and loose and breathable. Often many flower fields are slow to grow due to being too wet, and even stop growing. The cauliflower field should be kept moist and weeded and weeded in time.
Organic cauliflower is prone to downy mildew in the seedling stage and field high temperature and high humidity conditions. It can be sprayed with chlorothalonil, daisen zinc, ruthenium, antivirus, kelu, and Anke. During the growing period of cauliflower, it is prone to insect pests such as cabbage caterpillar, diamondback moth, and yellow stripe. The control can be used with deltamethrin, insecticidal double, chlorpyrifos, rutin, avermectin, Bt, agricultural land and other agents.
