As a country with a large population, the contradiction between the reduction of cultivated land and the increase in population is irreversible。
The right and accurate methods of cultivation can increase farmers ' income from cultivation and contribute to economic development。
I. Policy research on high-yielding cultivation technologies
1. Scientific sowing is carried out and potatoes need to be cut into small pieces before seeding。
After partitioning, appropriate plant ash is spread over the dent in order to prevent microbial infection. In general, seeding is done as late as possible。
The most appropriate planting time is at surface concentrations below 7°c, so that the planting time is as early as possible so as not to miss the best planting time and affect potato production. At the same time, the range and range of seeding is controlled and determined by the size of the seeding area。
Scientific land selection and land acquisition are the first steps。
Select the species that are resistant to cold, disease-resistant and high-yielding, and choose the fruit that is full of particles, smooth on the surface and without damage. Seed selection should be combined with local aridity, natural environment and soil conditions。
It should be noted that it is generally recommended that more than two varieties be selected, which can increase the disease resistance of potatoes and reduce pests. Although potatoes are more adaptable, the following points should be noted when selecting areas for cultivation:
The first is the area of high mountains with good irrigation conditions; and second, the area of potato planting within a year. After planting, vegetation should be treated within the area under cultivation to remove weeds. (c) improving equipment for drainage and precipitation systems。
3. Strengthening field management
At the onset, there is little need for fertilization, and the moisture of the earth blocks meets the needs of the seeding and habitat. If the soil is overwatered, vegetation becomes very humid and less permeable, resulting in oxygen in potato blocks, which can easily decompose the potato。
However, vegetation should not be too dry to affect the habitat and growth of seedlings. It is therefore necessary to observe vegetation closely. If the temperature is sufficient, the water must be replenished immediately. Soil moisture should be maintained at around 60 per cent during the seeding season in order to ensure that root embryos are well developed and that dwarf seedlings are cultivated. Large amounts of moisture are required for life in the long term。
During this period, the rate of sedentary leaves was relatively high. To meet their habitat needs, they need to fertilizer on time. At the same time, unnecessary sprouting should be removed, which would consume some photolytic products and would not be suitable for other breeding habitats. At the end of the period, the vegetation level was around 60 per cent。
The soil moisture must be controlled and replenished immediately before potato cultivation. Vegetation cannot be wet or dry. Ultimately, soil moisture can be contained within 60 per cent。
4. Fertilizer management
In fertilization steps, scientifically sound criteria should be followed and fertilized according to different natural sciences. Notably, the application of potassium fertilizer should be well controlled。
When sodium levels are too high and hydrogen levels are too low, potato yields are reduced. Remember not to over-fertilize during the fertilization process, so as not to cause it。
Ii. Development perspective studies
From the perspective of potato applications, it is widely applied not only in the food industry but also in industry. Most importantly, it can also be used to produce fuel-grade ethanol. In short, the potato market has great potential from the point of view of application, with promising development prospects and clear benefits。
In the southern region, there is a relatively large number of vacant agricultural land during the winter season, which can be used to grow potatoes. Use of crop rotation methods to accurately infiltrate vegetation and reduce waste of resources。
The key is to balance vegetation components, improve vegetation fertilization and achieve high potato production. Potato cultivation has good prospects for development in terms of its application and economic benefits. We should strongly advocate and recommend that farmers grow potatoes。
In the light of the above, in order to improve the efficiency of potato cultivation, it is necessary to have the scientific choice, to plant the land, to sow it in a timely manner, to manage the field, to control soil moisture, to apply fertilization in a timely manner and to ensure the healthy habitat of the potato。
Overall, potato cultivation has great development prospects and has played a significant role in promoting local forestry and agricultural economic transformation。
