Reasonable close planting cultivation techniques of dry cultivation Potato

Potato has a long history in Wulanchabu City, and its growth and development law is consistent with the local natural climate characteristics. It has obvious resource advantages and contains great development potential. In recent years, potato cultivation technology has also been greatly developed, with high quality and special use as the goal, excellent virus-free seed potato as the main line, integrating key technologies, forming technical model and technical system, and innovating the way of popularization. effectively improve the popularization rate and arrival rate of technology. First of all, it has accelerated the popularization and application of virus-free seed potato in our city, and vigorously promoted the cultivation of plastic film mulching in dry farming, water saving in dry farming, soil testing and formula fertilization, comprehensive control of diseases and insect pests, high ridge cultivation in paddy land and reasonable close planting techniques.

By expanding row spacing, reducing plant spacing, increasing planting density, improving ventilation and light transmission conditions, increasing input and reducing nutrient competition among plants, the commodity rate of potato was ensured. After two years of test and demonstration, this technology has a significant effect on increasing production and income.

The main results are as follows: 1. In our city, we mainly increase the sowing density by expanding the row spacing and reducing the plant spacing, generally large row spacing 75-80cm, plant spacing 25-30cm. There are 2800 trees per mu of seedlings, an increase of more than 1000 plants compared with traditional planting. 2. At present, this cultivation technique is being gradually improved and popularized. For example, in 2006, Zhang Zhenming, a villager of Village 27 in Xinghe County, planted 34 mu of potato project fields, and all the varieties were the original species of Kexin No. 1 allocated by the city promotion station. under the guidance of technicians, the project fields were planted in wide and narrow rows, with row spacing of 80 cm and plant spacing of 30 cm. The number of holes per mu is 2801, and the actual output is 2095 kg.
