Occurrence and control of potato tuber rot nematode
Fengning and paddock counties in the north of Chengde City grow more than 40, 000 hectares of potatoes a year, produce more than 800 million kilograms of seed potatoes and commercial potatoes, and store about 120 million kilograms of potatoes in winter. it is one of the four major potato production graveyards in the country. In recent years, due to the damage of potato tuber rot nematodes, the loss of stored potatoes was 5%-7% in 1994, and that of seriously damaged potato cellars was as high as 20%-30%. According to the data retrieved at present, this nematode is widely distributed in potato species in Asia, Europe, America and Africa.

Will the potato tubers still swell?
Tuber formation period is a period of tuber formation and rapid expansion, and the water consumption in the peak tuber period accounts for more than half of the total water demand in the whole growth period. It is appropriate to keep the soil water content up to about 70% of the maximum water capacity in the field, that is, to lift it into a ball and scatter one meter from the ground. In the later stage of tuber, that is, from one week to 10 days before harvest, irrigation should be stopped to facilitate the harvest.

Cultivation techniques of Green Potato
On the basis of traditional potato cultivation techniques, the cultivation technology of green pollution-free and high-quality potato is a cultivation technique by applying more organic fertilizer and less chemical fertilizer, selecting varieties with strong disease resistance and high quality, and using physical means to kill insects and sterilize. The specific points are as follows: 1. Turn the soil deeply in time to kill insects and sterilize. After the summer grain crops such as peas and wheat are harvested, turn the soil deeply in time and make use of the characteristics of high sunshine intensity in 3 dog days to kill underground pests such as grubs in the soil and kill the low temperature tolerant bacteria in the soil for the following year.

Key points of cultivation techniques of Spring Potato in Open Field
Potato is rich in nutrition, high yield, resistant to storage, long market cycle, can be used as a vegetable or food, deeply loved by the majority of consumers. Potato cultivation in the open field in spring is the most common cultivation method, and almost every farmer has to plant it. In order to obtain the high quality and high yield of spring potato in open field, the improved varieties should be selected first. Potato seeds must be imported from the north, such as "Dongnong 303" and "Kexin 4". Potato seeds must not be used as native species, such as "Dongnong 303" and "Kexin 4" transferred from the north, let alone native species which have been planted for many years, the varieties are aging and the species is seriously degraded. "Dongnong 303" and "Kexin 4" have been around for many years.

The feeding value of using potatoes to feed pigs
1. Nutritional characteristics: high yield of potato, low crude fiber content of tuber (4.4%), high biological potency of protein, and about 80% of dry matter of tuber is starch, which is higher than ordinary crops according to the amount of digestible energy and protein produced per unit area. The energy value is slightly higher than that of sweet potato, but lower than that of corn; the content of crude protein is about 9%, which is higher than that of cassava and sweet potato, the content of lysine is higher than that of corn; the content of carotene is very low, and the content of other vitamins is similar to that of corn. Potatoes contain antitrypsin factor

Scientific storage of potatoes
The stacking method selects a well-ventilated warehouse with a dry site, first fumigated with formalin and potassium permanganate, and then put potatoes into the warehouse, generally 750 kilograms per square meter, about 1.5 meters high, surrounded by crates, baskets or planks. Put a number of bamboo ventilators in the middle. This method is suitable for short-term storage and autumn potato storage. Ventilation storage method will be stacked potatoes in baskets, each basket of about 25 kilograms, stack height of 5 to 6 baskets is appropriate. In addition, it can be scattered in the library, with a height of 1.3 to 1. 5%.

Both of them can produce high yield by interplanting potato with insect-resistant cotton.
In recent years, the potato intercropping insect-resistant cotton model has been welcomed by the masses. According to the investigation, this model can not only achieve a high yield of cotton (90,100kg per mu of lint), but also "pick up" 1500kg and 2000kg of potatoes per mu. The main points of planting techniques are as follows. First, potato ① seed selection and sprouting. Virus-free varieties with early maturity, dwarfing and high yield, such as Holland No. 7 and Jinyin No. 8, should be selected with 80kg seed potato per mu. In mid-February, seed potato chips (40-50 pieces per kilogram) were cut into sunny beds or sheds.

Teach you to grow potatoes well (part 1)
First, the selection of seed potato for high yield mainly depends on the seed. The quality of seed potato affects the yield and income of growers. Therefore, it is a major problem to identify the quality of seed potato. Judging from the appearance of the seed potato, we should not only look at the size of the potato seed, but also look at the luster of the seed potato, which is good, fresh and without decay. The potato block is soft in the hand, and it feels crisp and soft with a knife. From the first half centimeter of the potato block, there is no ring rot (black circle). This can be said to be a better potato species. Good potato species, strong disease resistance, good quality and yield

Occurrence and Control of Potato Black Shank Disease
Symptomatic potato black shank is a bacterial disease that infects vascular bundles and can infect potato stems and tubers. The disease can occur from seed potato germination to the later growth stage, and it is the most popular in the seedling stage. Most of the diseased plants droop under water, the leaf color does not change, the whole plant wilts, and most of the black shins soften and rot. The color of the disease is yellowish brown, light brown or dark brown, light green and so on. The vascular bundles in the stem and the vascular bundles of the underground stem changed color basically into a ring-shaped stem and the connection between the base of the stem and the sweet potato blackened at first, and then developed near the ground to form a black shin. When the humidity is high, the black shin can rise to 3. 5% above the ground.
