Embodiment Construction

[0014] 1. The diseased plots should be rotated with non-host crops for more than 3 years.

[0015] 2. Combined with site preparation, apply lime 50-150 kg per 667 square miles (1 mu).

[0016] 3. Deeply apply fully decomposed organic fertilizers, topdressing ammonium sulfate and other nitrate nitrogen fertilizers.

[0017] 4. Check frequently to find diseased plants early, pull out diseased plants and burn them or bury them deeply before the formation of sclerotia, and sprinkle lime around the diseased point.

[0018] 5. After harvesting, the diseased residues in the field should be completely removed, followed by deep plowing at a depth of more than 15 cm.

[0019] 6. After sitting the melons, use grass circles and other things to pad the melons to avoid contact with the soil and reduce the infection of germs.

[0020] 7. In the early stage of the disease, 40% pentachloronitrobenzene powder can be applied to the base of the plant and the soil around it.

Abstract

The invention discloses a novel method for preventing and treating pumpkin southern blight. The novel method is characterized in that the purpose of preventing and treating pumpkin southern blight can be realized through processes such as crop rotation, combined soil preparation, soil acidity and alkalinity regulation, deep application of a sufficiently thoroughly decomposed organic fertilizer, regular inspection and early detection of diseased or infected plants, deep ploughing and drug control. This way is convenient to operate, can effectively increases the yield of pumpkins and effectively improve the quality of the pumpkins, and is suitable for preventing and treating pumpkin southern blight.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a new method for preventing and treating squash squash. Background technique [0002] Squash squash mainly occurs near the base of the ground stem or where the fruit contacts the ground. The disease occurs at the base of the stem, initially dark brown, water-soaked lesions, and then gradually enlarged, sunken, and tissue destroyed. The lower leaves of the diseased plants begin to turn yellow and wilt, and in severe cases, the whole plant withers. When the soil is removed, white mycelium bundles can be seen around the roots at the bottom, and the pathogenic tissue is rotten. Finally, many small tea-brown rapeseed-like sclerotias appeared in the diseased part. The fruit is diseased near the ground and is soft and rotten. The surface of the diseased part is densely covered with white silky mycelium, and many rapeseed-like brown small sclerotias are formed, resulting in reduced c...
