It has been centuries since its introduction into china from the next generation. It has been so popular for so many years and has contributed so much to the food shortage. Today we talk about the techniques and management methods of growing potatoes, so that you can learn how to grow potatoes。
I. Equipment, equipment
(b) land cover: deep tillage increases the soil layer and improves soil aerobics, contributing to the expansion of chips. The depth of deep tillage is typically 30 cm. Land with better earth power should be planted in order to grow, but low earth power and heavy sand should be used to level or low ground。
Fertilizers: since sweet potatoes are generally grown more often on sandy ground, it is necessary to apply bottom fertilizers and increase ground power to achieve high yields. Acre application of about 5 squares of earth dung is generally appropriate, 25 kg of ammonium phosphate and 25 kg of potassium sulphate。
Ii. Early and reasonable planting
Selection requirements: selection of high-quality products. Such as beijing 553 , new farmer 1, sinnon 431, potato 27, potato 8, potato 7 etc。
Time of planting: as a result of an evening frost before 1 may of each year, the planting time will be appropriate after 1 may to avoid it。
3. Cultivation density: cyanide varieties, more fertile plots, and cyanide varieties, and thin areas. There are 3,000-3500 acres of fertilized land and cyanide, and 4,000 acres of thin land and cyanide, with a distance of 60-70 cm and a distance of 30 cm。
Iii. Field management methods for red potato
1. Cultivation: plantation of seedlings to the south-east and wind so as to prevent wind damage. The soil is 1. 5-2 inches deep and 3-4 leaves appear on the ground. Pump water during planting and timely replanting to ensure full seedling。
Chinese tillage: medium tillage can decompress soil, increase soil aerobicity, increase temperature and eliminate weeds. Potatoes are drought-resistant crops, which should not normally be watered in the early stages, but may be watered by excessive drought. The concretization of chickens when they grow to about 1 foot has contributed to the small size of the chickens and the large number of branches, with some effect on the increase in production。
Medium-term control of chickens: july/august is a hot and rainy season, with fast-growing leaves and slow-growing chips, which should be primarily controlled to prevent long leaves. Acres of long chickens are sprayed 2-3 times, and short chickens, such as tubers, can be sprayed in appropriate quantities。
4 post-term management: water can be combined with 10 kg of urea in acre, used as cassava fat, with some effect on increased production。
This period is a period of fermentation of the chips, with the spraying of the cassava magnesium, which increases the absorption of the manure, the length of the inter-sectional length, the thickness of the leaves and the chlorophyll content, the diversion of nutrients to the chips, and the acceleration of the increase in the size of the chips。
Iv. Get the potatoes in time
The potato has not been harvested for a certain period of time, and farmers are allowed to harvest it in due course and according to their own circumstances, with maximum benefit. By the end of october, however, they were collected in order to protect themselves from the freeze, which affected revenue。
