Pumpkin is tropical, subtropical fruit and vegetables and is a warmer crop。
The appropriate growth temperature for papayas is 15-35°c. Plants are frozen to death when temperatures are below 6°c. Consequently, cultivation in the beijing region must take place in greenhouses with warmer conditions. It is not stringent in terms of soil requirements, and it is generally desirable to select land that is lax, fertile and well drained. Soil conditions in which groundwater levels are high or water is accumulated are prone to causes of decay。
I. Pre-plant seed treatment: seeds should preferably be disinfected with 500 times the pesticide tobzin, followed by 1% small soda impregnated for 4 to 5 hours to increase germinate rates. Once washed with fresh water, they are sprung in a thermostat at 32 degrees celsius and seeded when the skin cracks. Farmers can sow if they are able to soak with hot water for 12 hours without the above-mentioned conditions, and when they have washed up and placed clean towels on the stoves (which are mainly warm), they are checked twice at an early stage and wet, and the seeds open for four to five days。
Seeding: the beijing area uses winter and spring migration, usually in mid-october and late in the greenhouse. A plate of well-equipped trophic soil (which can be grown with vegetables) or a nutrient, which is then set up in the nursery bed, sowing with a small hole on its finger, and sowing one seed each. It's a cover, water, cover. It would be better to mix decomposition or farm fat in pre-smoking beds。
Iii. Management of seedlings: usually seedlings occur about 10 days after planting. After seedlings are produced, the soil is often wet, but not wet. When a seedling grows between two and three real leaves, the moisture is properly controlled and fattening can be carried out once every 15 days when the leaves come out。
Iv. Cultivation and fertilizer management: the beijing area is generally ready for planting in mid-february. Owing to the size of the papaya canopy, it is generally possible to use wide-banded and dense plants with a range of 1. 5 m x 2. 5 m. It is designed to dig deep, 60 cm in diameter and 40 cm deep. When planted, do not try to make a glass of mud loose when the cup is stripped, so as not to hurt the roots, and finally to take the root water and cover. Follow-up fertilization, i. E. Outside the drip line, began 10 to 15 days after planting. Quick fertilization is applied every half month thereafter. As temperatures rise, attention is to be paid to defiling and ventilating in order to avoid the burning of seedlings, the membranes can be completely removed after “five one”. Cultivation is expected to increase as the plant grows, with heavy fertilization starting in the current gratuity, which is applied once a month during the six months to october when the fruit develops. With enhanced fertilizer management, the results could be realized in mid-june. It will be ready for harvest after october, when warm conditions are in place。
V. Pest and pest control: the diseases most affected by papaya seedlings are diseases such as disease, sudden fallout, anthrax, powder, etc., which should be prevented by periodic spraying of fungicides, with the use of rhesus manganese zinc, tobuzin and polybacteria. When planted, it is mainly caused by foliage, anthrax, powder and foliage, and the main vector for transmission of foliage is aphid, which should be sprayed in time. The papaya pests in beijing are mainly aphids, which can be used for 10 per cent of the aphids (over and over) or against aphids. Spray concentrations are not too strong and papayas are vulnerable。
