Embodiment 1

[0016] A method for joint prevention and treatment of spring potato drought and late blight, comprising the steps of:

[0017] 1) Select disease-resistant varieties: choose varieties that are resistant to late blight;

[0018] 2) Establish a disease-free seed potato field: select disease-free seed potatoes and sow whole potatoes. During the plant growth period, carefully inspect and remove diseased potatoes by root. After harvesting, store them at low temperature for sowing. Carry out full drying and selection, and spray chlorothalonil, kelu and metalaxyl on the surface of the seed potatoes;

[0019] 3) Strictly handle the seed potatoes: first soak the seed potatoes in warm water at 40.0°C for 1.0 minutes, and then soak them in warm water at 50.0°C for 15.0 minutes. The amount of water is 4.0 times the amount of seed potatoes. ready to sow;

[0020] 4) Deep seeding and deep cultivation: when seed potatoes are sown, the implantation depth is 5.0 cm, and the depth of soil cult...

Abstract

The invention discloses a method for jointly preventing and treating drought and late blight for spring potatoes. The method includes steps of 1), selecting disease-resistant varieties with resistanceto the late blight; 2), establishing disease-free seed potato farmlands, to be more specific, carefully choosing disease-free seed potatoes, sowing whole tubers, carefully checking plants in plant growth periods, rooting out diseased potatoes once the diseased potatoes are found, storing the seed potatoes at the low temperatures after the seed potatoes are harvested so as to allow the harvested seed potatoes to be sown, sufficiently airing and sorting the seed potatoes before the seed potatoes are stored in cellars and spraying chlorothalonil, cymoxanil and metalaxyl on the surfaces of the seed potatoes. The method has the advantages that the disease-resistant varieties are selected, the disease-free seed potato farmlands are established, accordingly, disease sources can be reduced, and center diseased plants can be decreased; deep planting and cultivating are favorable for growth of bud seedlings, effects of protecting tubers further can be realized by means of deep planting and cultivating, the tubers can be prevented from being easily infected by fungi, accordingly, loss due to rotten potatoes can be reduced, and the germ carrying quantities of the tubers can be lowered; the drought and the late blight are jointly prevented and treated by the aid of water retaining agents and compound liquid preparations with fluopicolide and propamocarb, so that drought-resistant and disease-resistant treatment can be carried out on the potatoes, and the yield of the potatoes can be greatly increased.
