While celery is relatively resilient and is currently distributed throughout the country and is available for four seasons, some management practices are differentiated from other seasons due to high summer temperatures. The summer celery management technique is now briefly shared。
1. Choice of varieties
The relatively high summer temperatures are not conducive to the growth of celery, and therefore preference should be given to the cultivation of well-heated and resilient varieties, such as the eight-step sacrilegel, which are native farmers。
Seed treatment
The cold-water immersion seeds are replaced with water 24 hours a week before seeding, and many times with poaching until the water is cleared, and then the seeds are packed with wet cloth for seedling. In the summer heat, the proper increase in moisture is needed to accelerate the seedling process。
3, seedling planting
The planting of celery in the summer also requires strict control of planting densities between celery, and it is suggested that the length of the line should be around 8 x 11 cm. At the same time, be careful to control the temperature when seeding. When the seedlings grow around five leaves, they begin to grow. During planting, separate planting is carried out according to the size of the seedling。
4. Plantation management
Prior to planting, the pre-harvest season was tumbled, tanned for three to five days, acres were applied with a high-quality organic weight of 5,000 kg, and dredged to the ground. In the north, there are more flats, in the south, more highs, with a width of 1 - 1. 7 metres. And plant it with its roots, and do not bury its leaves。
Five, set the roof to cover the sun
After the seedlings have been planted, the shelter is prepared and then covered with a sunnet. The sunnet can be black-dominated, reduce surface temperatures, improve field climates, and be very beneficial for celery production and light co-operation。
6. Fertilizer management
In general, three to four fats are followed, which are applied evenly between the lines with a mixture of decomposed dry dung and compound manure, and can be used to rinse decomposed decomposed water, which is then poured into the shallow water. In general, one application requires water and no water is required in the event of rain。
7. Pest management
Premature diseases, stale diseases and aphids are the main pests. In the early stages of the disease, 75 per cent of the fungus was sprayed with 600 times the fluid spray or 0. 1 per cent of the sulfur powder sprayed with 0. 5:200 bordeaux fluid, 667 square metres of sprayed with 30-40 kilograms, with one blow in seven days and 2-3 in a row; the pests could be treated with 0. 4 per cent of the americin-killer 400-600 times the spray sprayed with 0. 1 per cent or 50 per cent of the dichlorvos 500-600 times the spray sprayed with 50 per cent。
