Embodiment 1

[0018] A cultivation method for preventing and treating downy mildew of broccoli, is characterized in that, comprises the following steps:

[0019] 1) Select peat, perlite, and vermiculite, and add 1kg of compound fertilizer to each m³ of the mixture of the above three as the substrate material. After mixing evenly, seal and decompose at 28°C for 70 days to obtain the broccoli cultivation substrate. Broccoli seeds are sown on the cultivation substrate;

[0020] 2) After sowing the broccoli seeds and before the emergence of the broccoli, sprinkle a Chinese herbal medicine preparation on the cultivation substrate every 3 days. The Chinese herbal medicine preparation is extracted from the following raw materials in parts by weight: 6 parts of garlic, 8 parts of Coptis chinensis, and 8 parts of chamaema chamaejasme 10 parts of Snakevine, 2 parts of Artemisia argyi leaves, 8 parts of Centella asiatica, 6 parts of Pueraria lobata;

Abstract

The invention relates to the technical field of agricultural planting, and specifically relates to a cultivation method preventing broccoli downy mildew. The method comprises the following steps: (1)treating a nursing substrate; (2) after broccoli seeds are sown and before broccoli sprouts, applying Chinese herbal and crude drugs preparations once on the culture substrate every three days; (3) in a broccoli seedling growing period, performing topdressing once on the broccoli every 20-30 days; (4) in a broccoli ball-flower growing period, at 9 o' clock to 11 o' clock in the morning, sprayingan insect preventing spray solution once cooperated with watering. Compared with a conventional pesticide pest resistance method, the method performs pest prevention in advance in different planting stages of broccoli, and obviously reduces range and types of broccoli downy mildew, and would not cause chemical pollution on broccoli fruits. The method can also improve yield of broccoli, and cultured broccoli is green and organic.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a cultivation method for preventing and treating broccoli downy mildew. Background technique [0002] Broccoli is also called broccoli and green cauliflower. It is a high-quality vegetable with high nutritional value. It has the functions of health care and beauty. It is a high-end vegetable that is popular all over the world. In recent years, due to the increase in consumer demand and the adjustment of the agricultural industry structure, the planting area has increased year by year. With the development of the broccoli industry and the increase in the number of years of planting, various diseases have become increasingly apparent. [0003] Broccoli downy mildew, the lower part of the leaves will have yellow spots with inconspicuous edges and limited by the veins, which are polygonal or irregular, and some have slightly depressed purple-brown or gray-black irregula...
