Blues, also known as eggplants, earthworms, plums, etc., are native grass plants. The coast of the central sea of origin, which entered china in the sixteenth century, is now cultivated throughout the country. The three types of blue, white and purple tubers, which eat vegetables with their roots and nuts, are white and thin, and can be fresh, cooked, fried or pickled, etc., are highly market-oriented. At the same time, there are many farmers who grow blues, the largest production of which is in the interior of mongolia and the heilong river. So what's the best environment to grow blue? And how to grow and manage to grow large and round blues. Here's what we'll do. Blue method:
Green blue plan
I. Choosing which environment is best developed
The blues like to grow in warm, suny, ventilated and suny environments. Blue is resistant to both high temperature and low temperature conditions. It has a growth temperature range of 10-35°c and although it is resistant to high temperature of 35°c, it is stunted in high temperature weather. The blues are resistant to cooling -10°c, with a safe winter in the south and the most suitable growth and development temperature is between 15 and 30°c. For moisture requirements, both drought-resistant and damp-resistant, if soil moisture is too dry, audible blue ball development and reduced yield, and the soil is too damp, causing disease and death in the plant, preferably by controlling soil moisture at 60-75 per cent. Blue is not much of a soil requirement and can be grown as long as the earth is thick. Agricultural crops in general recommend the choice of sandy land for cultivation with soil laxity, good air permeability, fertility and high water fertility. In nutrients, the three factors are nitrogen, phosphorus and potassium fattening, and the period of small seedlings is dominated by nitrogen, and phosphorus fertilizers are appropriate and are subject to additional potassium fertilisation during entry into the end of the ball。
Ii. Strategy management technology
1. Timing of planting; field planting of sorghum in the south and north is generally done in the early springs of february-march or in the autumn of september-october. In colder areas, such as inner mongolia, xinjiang and heilong river, cultivation is done more than once a year, with summer sowing in autumn harvests。
B. Cultivation of seedlings: 320,000 to 5 taels per acre, so that seeds are immersed in 50°c hot water for half an hour, with 1 gram of potassium permanganate added to the water. The seeds are then pumped once, then immersed in 30°c water for three hours, and dried but seedable. Choosing a 30-square-square-square area requires deep ground tan, preferably with a layer of dry straw to burn it once in the soil, to achieve better ash seedlings, both as fertilizer and disease- and pest-proof. Before seeding, inputs of 200 pounds of manure for the decomposed farmers, flattening the fat with the earth, extracting a small amount of soil, sowing it, then covering a centimetre of fine soil, sowing a proper amount of grass ash and pouring water once in a while until the soil is humid. Early spring seeding suggests an arched membrane to keep warm and humid, with seedlings emerging about a week later, and when a blue seedling grows five centimetres higher, it is best to have an inter-shot seedling once and to raise too thick a seedling at a distance of three centimetres. It is not possible to fertilize during the period of seedlings, and it is possible to replant them at about one month's age。
3. Bluefield requirements; select a field that has not been grown in a single year, preferably before wheat, maize, watermelon. After harvesting the crops, the sun is used for the destruction of bacteria contained in the soil, the soil is released and the soil fertility is increased. A few days before the planting, the ground was refined again and the bottom manure was applied, 5,000 pounds of corroded organic fat per acre, 60 pounds of nitrogen, phosphorus and potassium compound fattening, and the soil and the fatty were ploughed apart, with the proposal to grow in the spring into a flat patch that could be made in the autumn, with a width of 20-25 centimetres deep in the drain。
4. Replant planting; it is best to choose the dark and sunny afternoons for planting, before planting, to pour water on the small seedlings once they have grown up, when the soil is wet, to lean with their hands on the ground, and then with a little shovel and a little bit with the soil, so that the roots are not dumped and the rate of survival is high. The plant density is typically 50 centimetres away, 30 centimetres away, with 3500 to 4,000 plants per acre. After planting, water must be watered in a timely manner, once a day during the previous few days, to promote fast and slow seedlings and to reduce the number of times when growth stabilizes in order to meet the need for dry water。

5. Field management techniques
1 fertilizer management; in terms of moisture, small seedlings require smaller moisture and excessive moisture lengths. In order to prevent the plant growing, the period is generally free from heavy water and the soil surface is dry until the tubing starts to expand. Sluice is bred 2-3 times throughout the life cycle, and chinese farming combines with fat water to chase a nitrogen fertilizer without application. When the blues were found, they began gradually increasing the amount of water to keep the soil humid, while at the same time pursuing fattening, using 50 pounds of compound fat per acre, with root out or flushing, with a blue tubing period beginning to swell, and with 2 pounds of phosphate potassium per acre pouring 1,000 pounds. For some farmers who are under-cultivated, the direct use of decomposed manure and grass and ash can be evenly mixed, with more than 10 days of draught and three times a day, is no less productive than fertilizer. 2 crawling; blubbers can be used either as seedlings or not, and generally not for poorly grown seedlings. But it's too well-growing to advise a moisture, which can control the protege, which is to take place in the morning and avoid the rain。
Insects and pests are protected; blue pests rarely occur, and the general source of pests and pests is high temperature, dampness, overdensity of cultivation, which can only occur without ventilation or personal management, provided that they are well managed and do not use pesticides at all. If there is any doubt, it is recommended to use polymix to prevent disease, aphids to prevent pests, and the amount used is indicated by the manufacturer, since the percentage varies depending on the pesticide content of each plant。

6. A good harvest; blue tubers grow up to a certain amount of hours to collect them in a timely manner, with a break in their late harvest and a poor taste and quality, and can be picked according to market quality requirements. Usually, 60 to 70 days after planting, when wax powder is present on the surface of the blue tubing, or when the plumes of the head of the tubing are plastered and the harvest is highlighted。
Summarizing these points, these are about the best environment for planting the blues, and about the techniques of planting the blues to grow large and round. It is hoped to help friends who like to grow blues, some of which are drawn from individual planting experiences, for information purposes only. Friends, do you have any better ways to grow?
