It is delicious. Haiyang white jade cucumber, also known as white cucumber, also known as "Liyuan white", is one of many cucumber varieties. White cucumber is a heat-resistant and disease-resistant variety selected from local varieties in Haiyang Seed Station for many years. It has passed the appraisal organized by Haiyang Municipal Science and Technology Commission, and it is a real Haiyang specialty.

Similarities and differences between white cucumber and green cucumber in cultivation. The cultivation techniques of white cucumber and green cucumber are basically the same. According to the characteristics of white cucumber, the following points should be paid attention to during cultivation:

1. Sowing date selection: white cucumber is extremely early-maturing and has strong cold tolerance. The sowing date in South China and Central China is generally around 65438+February 25th-the following year 65438+ 10/5. It can be listed around April 20, earlier than cucumber. The price is relatively high, which can reach about 5-6 yuan per catty, bringing good economic benefits to growers.

2. Preparation before sowing: seed disinfection, cold-resistant exercise, greenhouse disinfection, seedbed soil preparation and other methods. Similar to common early-maturing cucumber cultivation.

3. Planting density: The main vine of white cucumber has almost no lateral branches, so the planting density is appropriately increased compared with that of green cucumber. Generally, two rows of plants are used in Changsha, with a reference spacing of 40cm×70cm, about 4,000 plants/mu, or a reference spacing of 35cm×60cm per plant. The average seed consumption per mu is about 150g.

4. Post-planting management: the seedling stage of white cucumber is the key period, and the seedlings are relatively thin, so it is necessary to fertilize more and more frequently. Once this period has passed, the later management will be much easier. At the initial growth stage after planting, topdressing with 2-30% fecal water for 3-4 times in sunny days to make the seedlings grow rapidly.

5. Strengthen foliar fertilization in the late growth stage to ensure the growth of young melons and delay the senescence of functional leaves. Methods: 0.3%-0.4% potassium dihydrogen phosphate was sprayed on the leaves.

6. Strengthen pest control: mainly strengthen the prevention and control of downy mildew. Generally, metalaxyl, Ray Domil, Dupont clot and chilblain can be used for 2-3 times.
