Prevention and control of diseases and insect pests of edible fungi and management of broccoli after transplanting in spring

After the beginning of spring, in the middle and last ten days of February, they moved into the field one after another and adopted plastic film cultivation. The row spacing of the colonized plants was 55ml 65cm, and the density per mu was 1500mur1800 plants. After planting, spraying 500mur700 times of the new high-fat film solution to prevent the aboveground water from evaporating, the seedlings did not transpirate, cut off the diseases and insect pests, shorten the slow seedling period, quickly adapt to the new environment, and grow healthily.

40 kilograms of phosphate fertilizer per mu, 20 kilograms of potash fertilizer or ash fertilizer, and 10 kilograms of nitrogen fertilizer. After budding, the rapidly available nitrogen fertilizer was increased by 20 kilograms to prevent the hollow or rot of flower heads and stems, and the application of potash fertilizer at the stage of flower head formation had a significant yield increasing effect. Combined with two external root application of trace elements, borax potassium dihydrogen phosphate, the concentration was 0.1%.

Because the leaves of green cauliflower are broad and thick green, it is damaged by Pieris rapae in the whole growth period, so it can be controlled by 1000 times of quick killing and 800 times of new high lipid membrane. (Qinghan)
