The usage of Toyota Golden potassium on Potato
Potato is a typical potassium-loving crop. It takes 0.5 kg of nitrogen, 0.2 kg of phosphorus and 1.06 kg of potassium to harvest 100 kg economic yield (tuber). It can be seen that potassium is twice as much as nitrogen and 5 times as much as phosphorus. Toyota gold potassium has been applied to potatoes by farmers in Tangshan, Tianjin and Wumeng, Inner Mongolia for several years, and the effect of increasing production is obvious. It can be used in two ways:
1. Seed dressing: according to 150kg seed per mu, Toyota gold potassium is available (zip code: 454650, address: Jiyuan Toyota Fertilizer Co., Ltd., 39 Tiexi Road, Jiyuan City, Henan Province) 2 bottles (500ml). After slicing the seed potato, spread it on the plastic sheet or mat in a place away from light (not too thick, about 10 cm) to dry it. When there is no water (liquid) on the surface of the cut potato, spray an appropriate amount of water evenly on the seed potato with Toyota gold potassium. In order to make the potato pieces stained with Toyota gold potassium, you can turn them appropriately, if you have urged the buds to pay attention to do not hurt the buds as far as possible, and then sow seeds.
2. Basic application: according to 2 bottles (500 ml) per mu of water, evenly mix it in the right amount of mature agricultural fertilizer, spread it in the sowing ditch (or spray the appropriate amount of water evenly in the sowing ditch), and sow seeds.
3. Precautions: no matter which method is used, the soil should be covered in time after sowing, and the direct sunlight time should be shortened as much as possible in the whole operation.

Flavor preserved potato
Technological process: potato → washing → peeling → finishing → dicing or strips → pre-boiling → cooling → disulfide solution treatment → dry → puffing → adding flavor enhancer → packaging → finished products. Operation points: ① peeling: using lye peeling or infrared radiation peeling, the effect is better. ② molding: cut it into dice, strips or other shapes according to the requirements of the product. ③ drying: the moisture content of the raw material should be strictly controlled, and the drying can be stopped when the moisture content of the raw material is reduced to 2.8-3.5%. ④ puffing: using gas

Control of potato diseases
Disease is one of the important factors affecting the yield and seed character of potato in winter. The main diseases and control methods of potato in winter in Yunnan Province are introduced as follows: virus disease control methods: selecting virus-resistant varieties and virus-free seed potatoes; pulling out diseased plants in the field; timely control of aphids. Fungal disease one is late blight. Control methods: selection of disease-resistant varieties and disease-free seed potatoes; timely removal of central diseased plants and intermediate ploughing and weeding; chemical control. The second is early blight. Control methods: selection of disease-resistant varieties; chemical control. Control methods of bacterial diseases and ring rot: selection
