A lot of people want to grow melons, and they don't know how many months they've been planting. The melons are temperature-sensitive and their planting time directly affects seedlings, growth and production. Early seeding is not enough, seeds rot in the ground and, when seedlings occur, they are affected by low temperatures. It's late, it's chronically inadequate and it's not mature enough. This paper describes the timing of the cultivation of melons in different cultivation methods and regions in large white language, with no excess content and can be used as a direct reference。
The melon is grown not only for months, but for temperature. Seed sprouts require temperatures above 15°c and the most suitable temperatures are 25-30°c. When the melon plant grows, the temperature is 25-30°c during the day and not less than 15°c at night. At temperatures below 10°c, melons largely stopped growing. The temperature is below 5°c and the plant is damaged. The temperature varies widely between the north and the south of the country, with different planting times, and cannot be used uniformly for a month。
The direct planting of melons in the open is a common practice of many people. In the northern regions, such as north china, north-east china and north-west china, field seeding generally took place in mid-april and early may. During this period, local temperatures are stable and soil temperatures are higher and suitable for seed seed seeding. High temperatures in the south allowed for field planting well in advance, usually from late march to early april. Before planting, the land should be rebuilt and weeds and stones removed. The seeding is controlled at depths of 2 to 3 cm, with two to three seeds in each of the caves, and the dust is planted and water is poured. Keep strong seedlings when they come out, and extra seedlings are removed。
Covering the membranes with membrane can increase the temperature of the ground and protect the guacamole, with earlier planting times. In the northern region, membranes are grown, usually between early april and mid-april. The membrane cultivation in the southern region was generally in late march. The seeding is preceded by a full fertilization, then by covering the membrane and then poaching on the membranes. The membranes can reduce water evaporation, prevent weed growth, speed up seeding and allow melons to grow early. The membranes are grown in membrane and are fully grown, with rapid pre-growth rates。
The method of planting seedlings is suitable for farmers wishing to harvest melons in advance. Feeding can take place in large sheds or indoors. In the north, seedlings took place in the middle of march, until external temperatures stabilized, with seedlings growing between three and four leaves before planting, usually between mid-april and late april. The southern region had nursery time from late february to early march, and the planting time from late march to early april. It is important to keep the temperature and moisture under control and avoid the growth of the seedlings. (c) do not damage the roots of the plant and water it in time to help the seedlings live。
Problems arise when melon cultivation is premature or late. Cultivation is premature, external temperatures and soil temperatures are low, seeds do not sprout normally in the soil, and rotten species occur. Even if the seedlings are produced, the seedlings grow slowly at low temperatures, with leaves yellowing, weak and even freezing to death. Late planting and the production of melons have been reduced for a long time, and by the harvest season the fruits have not matured properly, are not sufficiently sweet, are small and yield low. Late temperatures in some areas have declined and melons have not matured normally。
The management of the melon is also simple. The water is based on the dry and wet condition of the soil and does not overwater the fruit before flowering, avoiding the long planting of the plant. After the fruit, the water supply is guaranteed, and during the expansion period the fruit needs more moisture. Fertilizers are applied at the bottom and in pursuit of fertilizers. Field weeds must be cleaned in time to avoid competition for nutrients. The melon needs a whole tumble, a proper chicken and an increase in the seating rate。
In general, the timing of melon cultivation is determined according to the region and the method of cultivation. The field seeding takes place at a stable spring temperature, with membrane cultivation taking place about half a month earlier and seedlings being planted before planting. As long as time is right and temperatures are met, melons can grow, grow and produce normally. Growers do not broadcast blindly early, and choosing time according to local temperature reduces losses and increases harvests。
