Planting time and method of Spring Cucumber
Spring cucumber is planted by seeding grafting method, generally sowing seedlings in winter, planting begins after night frost, and Beijing and Tianjin areas begin at the end of April.
Spring cucumber planting points:
1. seedling management
Spring cucumber seedling period is in low temperature season, temperature management should be carried out according to the temperature requirements of different seedling stages. Pay attention to the change of seedbed ground temperature, and adopt soil warming measures when the temperature is low. In addition, in its seedling period is short sunshine, weak light intensity in winter, so it is necessary to timely remove the cover, increase the light time.
2. water and fertilizer management
After each watering, it is necessary to hoe, loosen the soil, improve the ground temperature and promote the development of roots. After the cucumber seedlings slow down, they should be cultivated many times. Root melon after sitting to topdressing, can open the ditch into decomposed, mashed manure or decomposed dry chicken manure. After fruiting melon, increase watering frequency appropriately. During the peak period of fruit setting, the vegetative growth and reproductive growth of the plant entered the vigorous stage, and the amount of fertilizer required was greatly increased. Under normal circumstances, 1-2 days should be watered, and it is appropriate to water in the morning or evening. Also topdressing, generally every 7-10 days after 1, hot summer season, pay attention to drainage, in case of rotten roots.
3. trestle leaf picking
Cucumbers should be supported after pulling vines. Multipurpose herringbone frame. Bind vine when plant height is about 25cm, and then bind once every 3-4 leaves. When the plant stem vine climbs to the top of the frame, it should be picked in time to promote the occurrence of lateral vine, and the lateral vine leaves 2-3 leaves after the melon. To the main vine fruit melon-based varieties, stem side vine should be removed in time. In the late stage of fruit setting, diseased leaves and old leaves should be removed in time to improve ventilation and light transmission conditions.
4. pest control
In addition to paying attention to crop rotation, soil disinfection and humidity in the shed, Bordeaux mixture can be sprayed on downy mildew. Powdery mildew can be sprayed with 200 times wettable sulfur powder suspension. In addition, attention should also be paid to the prevention and control of blight, downy mildew, aphid, yellow melon, fruit fly and other diseases and insect pests.
Spring cucumbers can be harvested after planting in January, and early harvest should be appropriate to improve yield.

The reasons for the death of Morchella are as follows: 1. Humidity is too large or too small: humidity will cause poor ventilation, resulting in death by water stains or bacterial diseases, while too small will dry up and die. two。 High temperature and humidity: the temperature of the mushroom shed is too high and the humidity is too high, causing the mushroom bud to be stimulated and died.
