How to grow white cucumbers?

1. Apply sufficient base fertilizer

In general 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, evenly spread every 667m2. After deep ploughing of 25cm, the land is prepared and the width of the flat border is 1.1 to 1.2m.

two。 Sowing at the right time

The cultivation of strong seedlings in the Huang-Huai River Basin in spring can be sowed and raised in the middle of March and planted in autumn from mid-June to late July. Sawdust can be used to raise seedlings. Because of the air permeability, heat preservation and moisture preservation of sawdust, the seedlings are unearthed quickly and sturdily, and it is 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. Reasonable close planting

The growth potential of this variety is strong. In order to improve the utilization rate of light energy, the plant row spacing is 30cm × 60cm 667 square meters to protect seedlings about 3700 plants, which are cultivated on large shelves.

4. Scientific pruning

Because the main and lateral vines of this variety can bear melons, when cultivated in spring, the seedlings generally do not pick the heart, and when the main vine is close to the top of the shelf, pick the heart. 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. Strengthen the management of fertilizer and water

During the growth of cucumber, it is necessary to promote the combination of control and control, make the melon seedlings flourish, strengthen mid-tillage in the early stage, squat seedlings, and squat until the root melon is stable, enough to water the melon seedlings, otherwise watering too early will easily lead to the overgrowth of plants and 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. Control of diseases and insect pests

The main diseases of white cucumber are downy mildew, angular spot, powdery mildew and so on, which can be controlled by spraying DuPont Kelu, Anke manganese zinc, metalaxyl, dt fungicide, streptomycin, methyl topiramate, trimethoprim and so on. 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.

How many jin of white cucumber per mu?

Cucumber is a vegetable that can be eaten with tender fruit. 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 slow down the development of the next melon. in particular, the harvest of root melons should be brought forward. The yield of white cucumber is 667 square meters 3000~4000kg.

What are the effects and effects of white cucumbers?

White cucumber white skin crystal bright white, with obvious heat-clearing and detoxification, thirst-relieving effect, rich in vitamin B2, vitamin C, vitamin E, carotene and other nutrients, as well as cucurbitacin, soft fiber and other ingredients, is a rare detoxification and beauty, promote metabolism of the ideal food.
