Time of field cucumber planting
The planting of open cucumbers occurs when no seedlings are available and the seedlings freeze to death. This paper describes the specific planting time of the open cucumber by geographical area and by type of cultivation, with reference to temperature requirements and special weather adjustment methods, which should be directly applied by the grower。
In the field of cucumber cultivation, the temperature and temperature are measured first. Cucumber seeds are sprouts and soil temperatures are stable at more than 15°c. Cucumber seedlings grow at temperatures above 20°c during the day and at no later than 10°c. In the open environment, temperatures are below 5°c for three days and cucumber seedlings are frozen. In the field of cucumber cultivation, it is necessary to wait for local temperatures and temperatures to reach the above standards and not to sow them blindly。
The climate varies widely among different regions of the country, with four regional descriptions of the time taken to plant open cucumber。
The south china region includes guangdong, guangxi, fujian, hainan and yunnan south. The region has experienced a rapid recovery of temperature after the spring, with no visible fallout. The field cucumber was live from late february to early march, and the planting of seedlings was scheduled for mid-february to late february. In areas with high temperatures throughout the year, the fall can be replanted and the autumn field till early september。
The yangtze basin area includes hunan, hubei, jiangxi, zhejiang, jiangsu, anhui and sichuan basins. The field cucumber was broadcast from late march to early april, and the planting of seedlings was scheduled for mid-march. In mid-march, the region was prone to winterization, which was followed by the preparation of film and cooling coverage。
The hwang huai sea area includes henan, shandong, the north-central south, south-west of the hill, and shaanxi guan. The field cucumber was broadcast live between mid-april and late april, and the planting of seedlings was scheduled for early april. The region was still experiencing cold weather in early april and the election took place in the morning。
The north-east and north-west high-cold regions include heilongjiang, jilin, liaoning, inner mongolia, gansu, ningxia and xinjiang. The field cucumber was broadcast live between mid-may and late may, and the planting of seedlings was scheduled for early may. The region is short-lived and must wait until the final frost is over before field cultivation takes place。
The field cucumbers are broadcast live and seedlinged in two ways, with different planting times。
The feed is distributed directly into the soil, 15 to 20 days later than the nursery. The air is preceded by the watering of the soil, with two seeds per den, two centimetres of thick soil and a strong seed。
Cultivation is first taken in the shed or indoor seedling, which is controlled from 30 to 35 days, and leaves reach three to four days before being moved to the open ground. The timing of planting is calculated, with the date of planting being set locally suitable in the field, which is pushed forward 30 to 35 days, i. E. The start of seedlings。
Special weather conditions were encountered during the planting process and the timing of the planting was adjusted。
In the event of a cold turn-off, the temperature will drop below 10°c and both live and shifting time will be delayed from 7 to 10 days. During the delay, nursery beds are kept warm and do not move earlier。
In consecutive rainy weather, soil water is accumulated and planting is suspended. When the soil is drained, the earth's surface is dried up and broadcast live, and wet earth seeding leads to the decay of seeds。
The local temperature is higher than the norm for the year, 10 days in a row, the temperature is met earlier, the time of live broadcasting and planting can range from 5 to 7 days, and spare membranes after early planting。
Summarize the time of field cucumber cultivation in the regions. South china 2nd to march spring, august to september autumn. The yangtze basin moved in late march and was broadcast live from late march to early april. The plant moved in early april and was broadcast live after mid-april. The plant moved in early may and was broadcast live after mid-may. All planting times are based on seven consecutive days of local temperature and temperature measurements。
The planting of open cucumbers, which check the temperature before setting the time, reduces the loss of seeding periods and increases the survival rate. You can leave a message about your province and city
