Prevention and Control of Edible Fungi Diseases and Plant Protection Management Technology of broccoli

For land preparation, we should choose fields with high and cool terrain, good drainage, ventilation and light, loose and fertile soil, clean up the previous crops in time, plough and expose them in advance, and evenly apply seedbed base fertilizer. 1000 kg of mature organic fertilizer and 20 kg of compound fertilizer per mu, plus 10 kg of phoxim granules, shallow ploughing, mixing, pounding, and then leveling to make the bed.

In seedling stage management, seed dressing with 800-fold solution of new high-fat film before sowing can ward off underground diseases and insects, isolate virus infection, strengthen respiratory intensity, improve seed germination rate, and pour sufficient water; then spread the treated seeds evenly in the seedbed, sowing amount is suitable, cover soil 1-1.5 cm thick after sowing, and spray 800-fold solution of new high-fat film to keep moisture and increase fertilizer to promote seedling emergence.

For transplanting and planting, loam or sandy loam with strong water conservation and fertility conservation should be selected in the field, and sufficient basic fertilizer should be applied, ploughing fully, soil preparation and bed preparation; reasonable close planting, watering root water while planting, rewatering once every other day, and timely spraying 800-fold liquid of new high-fat film can prevent bacterial infection, improve the ability of seedlings to resist natural disasters and shorten the slow seedling period.

In field management, after the plant returned to normal development at the end of the slow seedling stage, timely mid-tillage weeding, soil choking root cultivation, timely spraying seedling fertilizer (2.5 kg urea / mu with water), and spraying 800-fold liquid of new high-fat film to improve fertilizer utilization rate. Spraying vegetable Zhuangtuanling in time at the bud stage can make the plant stem stout and the flower bulb enlarged, at the same time, it can improve the ability of disaster resistance, reduce the amount of pesticide and fertilizer, reduce the residual poison and improve the natural taste of broccoli.

In the prevention and control of diseases and insect pests, downy mildew and soft rot are easy to occur in the growing period of broccoli, and the diseases and insect pests of Plutella xylostella, Pieris rapae and APHIS rapae should be sprayed according to the requirements of plant protection combined with 800-fold solution of new high-fat film to enhance the control effect.
