The following are the main elements of the techniques used for small winter melon field cultivation:
1. Selection of seeding periods and varieties it is desirable that the planting take place in the spring between the second half of february and the second half of march, when the temperature is appropriate for the growth of small winter melons. Choice of species: high-yielding varieties, such as coronary star 2 melons, coronary melons, melons 4 and so on。
2. Selection and preparation of land soil requirements: small winter melons shall choose fields with deep soil thickness, ease of drainage and fertile soil to avoid being associated with the reduction of disease. Land preparation: zirconium cultivation, 1. 2 m wide, zirconium, 0. 4 m wide and zirconium 35 to 40 cm high. 1000-1500 kg of soil fertilizer per acre and 30 kg of calcium per phosphate per acre before planting to provide adequate nutrients。
Sprouts and sowing seedlings: before seeding, seeds are immersed in water at 30 °c for 46 hours and then dryed to promote growth at 30 °c. Most seeds are seeded at 0. 51 cm long. The planting method is double-lined, with a distance of 80 centimetres and a distance of 50 to 60 centimetres, with approximately 1,500 plants per acre. Ten per cent of the faecal urine rinsing caves are used before planting, with two to three seeds per den, which are then covered with pine soil。
4. Field management temperature control: small winter melons grow at suitable temperatures of 18-28°c, and management measures, such as the construction of sunnets, should be adjusted in a timely manner in order to maintain suitable growth temperatures. Water management: keep the soil wet, but avoid water accumulation that leads to root decay. Timely irrigation and drainage based on weather and soil conditions. Pest and pest control: periodic field inspections to detect and combat pests and diseases in a timely manner can be carried out using a combination of agricultural, biological and chemical control。
The above-mentioned technical points could improve the production and quality of field cultivation of small winter melons。
