Planting techniques of White Cucumber

White cucumber is a kind of cucumber. Its main cultivation techniques are introduced as follows:

The main results are as follows: 1. For high-yield fields, it is required to apply high-quality farm fertilizer 5000kg, nitrogen, phosphorus and potassium ternary compound fertilizer 50kg, calcium superphosphate 20~50kg and spread evenly every 667m2. After turning 25cm deeply, the land is prepared for border, and the width of the flat border is 1.1m to 1.2m.

2. Sowing in time and cultivating strong seedlings in spring open field cultivation in Huang-Huai River Basin can sow seedlings in the middle of March, raise seedlings or direct seeding in autumn from mid-June to late July, and use sawdust to raise seedlings because of sawdust ventilation, heat preservation and moisturization. the seedlings were unearthed quickly and strong, and it was not easy to hurt the roots when dividing the seedlings. Strong seedlings require that the stem is about 1cm, the Internode is short, the length is about 10cm, the petiole is about 10cm, and there are 4-5 true leaves, which are spreading horizontally, thick, green, large crown but not sharp, many roots, thick, white color, strong and sturdy growth potential of melon seedlings.

3. The growth potential of this variety is strong in reasonable close planting. In order to improve the utilization rate of light energy, the row spacing of 30cm × 60cm is 667m2 to protect about 3700 seedlings, and the cultivation is carried out on a large shelf.

4. Scientific pruning because the main and lateral vines of this variety can bear melons, when cultivated in spring, the seedlings are generally not coring, and when the main vines are close to the top of the shelf, coring is carried out. In high-yield cultivation, the "one main and two sides" type can be used for pruning, so that it can be evenly distributed on the shelf, and light energy can be fully utilized to synthesize more nutrients.

5. Strengthening the management of fertilizer and water during the growth of cucumber, it is necessary to promote the combination of control and control during the growth of cucumber seedlings, strengthen mid-ploughing in the early stage, and squat seedlings, so that it is better to squat until the root melon is stable, and it is better to pour melon water when it is enough to fall on the melon seedlings, otherwise it is easy to cause the plants to grow too early and cause the danger of melons. The early flowering stage is mainly "control", and the melon fruiting stage is mainly "promoting". The principle of topdressing is to apply fertilizer frequently and thinly, and after root melon harvest, take "one clear and one mixed" alternately, topdressing urea every 667m2 every time 8kg or ammonium bicarbonate 20kg, so as to obtain stable and high yield.

6. The main diseases of white cucumber are downy mildew, corner spot, powdery mildew and so on, which can be controlled by spraying DuPont Kelu, Anke manganese zinc, metalaxyl, dt fungicide, streptomycin, methyl topiramate, trimethoprim, etc. The main insect pests are aphids, yellow melon, black melon and so on. Dimethoate, aphid lice net, trichlorfon, cypermethrin and other insecticides can be used to control.

7. Timely harvesting cucumber is a vegetable with tender fruit for consumption. When the length and thickness of melon strips increase to a certain size, but the seeds and epidermis have not yet hardened, they should be harvested in time, too late will not only affect the quality, but also fall seedlings. It will delay the development of the next melon, especially the harvest of root melons in advance. The yield of white cucumber is 667 square meters 3000~4000kg.
