Winter cucumber interplanting bitter gourd technology

Selecting good varieties of cucumbers should use high-yield and high-quality varieties that are resistant to low temperature, low light, high resistance to downy mildew, and resistance to wilt disease. Such as Jinyou No. 32, Zhongnong 21, Jinlv 21-8, Jinwang No. 6, Bonai, Xingke No. 8 and so on. Bitter gourd uses low-temperature, low-tolerance seedling light, the results of high temperature and humidity resistance, high resistance to anthrax and bacterial leaf spot disease and other diseases of the early-maturing and early-maturing high-yield and high-quality varieties. Requirements fruit color green, thick flesh, melon straight, melon 25 to 30 cm long, suitable for summer and autumn packing storage and transportation.

Timely planting sowing date calculation methods: 1. Overwintering cucumber from the sowing to fruiting melon initial period of about 92 days; sales over the years began to increase significantly, and the price is also significantly increased during the period before and after the heavy snow 10 days, namely December 2-12. Therefore, the suitable sowing period for wintering cucumbers is September 5-12. 2. Bitter gourd entered the beginning stage of guava cultivation 175 days after sowing. The sales price was 1 times higher than that of cucumber and the period of significant increase in bitter gourd sales volume was 10 days before and after the beginning of summer, that is, May 1 to 10th. Therefore, from the 17th to the 27th of last year, a suitable sowing date for the overwintering bitter gourd was planted for the overwintering cucumber shed.

After planting cucumber and interplanting balsam pear for 10 to 12 days after grafting, grafted cucumber seedlings were cut off for 7 to 10 days, and cucumber seedlings were planted for 4 to 5 true leaves. Before the colonization, the north and south of the river were planted with a centipede distance of 120 centimeters. The intertemporal crevicular groove was "V", the crevice width was 35-40 centimeters, and the depth was 25 centimeters. The arched surface was arched. Each row of plants is planted in double rows, and a shallow ditch of 40 centimeters wide and 15 centimeters deep and 8 to 10 centimeters deep is placed on the surface of the plant. The cucumber seedlings were planted in the shallow ditch at a spacing of 33 to 37 cm, and the grafting interface was higher than the sorghum surface. Then cover a silver-white mulch with a width of 130 cm, break the membrane and place the seedlings, and seal the membrane mouth with soil. From October 17 to 27, cucumbers were planted at intervals of 2 to 3 meters in the north-south direction of the cucumber plants. After watering, bitter melons were planted. 2 to 3 days before sowing, the seeds are soaked in 55~60°C hot water for 30 minutes, then soaked in warm water of 25°C~30°C for 48~72 hours, then directly sowed on the spot, 3~5 particles per hole, and covered with soil 2 ~2.5 cm thick. After the emergence of each hole selected to retain a strong seedlings.
