Management and protection of high yield model of broccoli in autumn and winter and notes on the introduction of edible fungi

The drought and waterlogging tolerance of broccoli is poor, it needs a lot of water during the growth period, but the water requirement is relatively strict, and it is often required to keep the soil dry and wet in cultivation. In the early growth stage of broccoli, it is mainly to grow leaves to expand the assimilation area and to produce and accumulate nutrients for the generation of reproductive organs. During the whole growing period, nitrogen nutrients should be supplied, especially during the vigorous growth period of rosette leaves. In the process of flower bud differentiation and flower head development, it is necessary to increase the application of phosphorus and potassium fertilizer combined with photosynthetic nutrient film to enhance the photosynthetic capacity of nutrients and chlorophyll, advanced environment-friendly plants to increase fertilizer, yield, color, leaf thickening, dry stem strong compound film. It can help plants absorb a lot of light fertilizer, light energy, light, compatible conventional fertilizers and nutrients to the limit of plant growth and development. One application is beneficial for the whole year. The main diseases harmful to broccoli are soft rot, sclerotiorum and black rot. The main method of control is to carry out rotation to prevent the spread of insect pests and prevent mechanical damage. In the early stage of the disease, the new high lipid membrane plus chlorothalonil can be used for prevention and treatment in time. Timely harvest is an important measure to ensure the quality of broccoli. Early harvest affects the yield; too late harvest, the flower ball is loose, the surface is uneven. The harvest standard is suitable when the flower bulb is fully large, the surface is smooth, and the flower branches at the base of the flower ball are slightly loose. During harvest, there are 5-6 leaflets outside the bouquet and sprayed with 500-fold liquid of new high-fat film, which can prevent water evaporation, prevent bacterial infection, resist freezing and heat preservation, and prolong the shelf life.
