The cucumber roots in the greenhouse are weak and have poor absorption, but they have strong fertility and fertility. Understanding the growth characteristics of cucumber, skillful fertilization, scientific management, can make cucumber high quality and high yield.
Seedling nutrition soil requires loose texture, good ventilation, adequate nutrients, pH value 5.5 - 7.2 within a range, with reference to camp preparation method of raising soil tomato formulation. In the preparation of nutrient soil, the addition of 2 - 3% of superphosphate in the total amount of nutrient soil has a significant effect on promoting the growth of seedling roots and cultivating strong seedlings. Using nursery seedbed, when transplanting, after 2 kg Manyuanchun mu micro fertilizing transplanting biological agents or dipping, can stimulate root growth and improve survival Huanmiao, nurturing seedlings.
Cucumber roots mainly in 15-- 25 cm topsoil, salt poor, the amount of each fertilizer is not too large, the number of dressing to be more, to master the principles of "frequent meals" in.
1. Apply enough base fertilizer. 5000 kg general Mushi decomposed manure (first with Manyuanchun fermentation agent ordinary full maturity of organic fertilizer), diammonium phosphate 20--30 kg potassium sulfate 20 kg, 50 kg as basal fertilizer superphosphate. Years greenhouses need with addition of 2 kg of ferrous sulfate, zinc sulfate 2 kg, 1 kg borax or boron to good Manyuanchun 2--5 bags and Manyuanchun to good bacteria 2--5 bags. After the fertilizer is evenly spread on the ground, it only needs to be turned over once to function, and the utilization rate is quite high.
2 , skillfully plant fertilizer. Selection of bio-organic fertilizer for planting when planting fertilizer, bio-organic fertilizer Mushi generally 40 - 50 kg. When fertilizing, you can concentrate on the ridge line, then lick it, then you can ridge.
3 , the long-term topdressing. General need fertilizer after planting cucumbers 8--10 times, after fruit set, yield of cucumber basic form, melon vine fertilizer not only does not cause excessive growth, but also promote increased production. Cucumber dressing for the first time in early fruiting, Mushi urea 7--9 kg (ammonium 12--15 kg), potassium fertilizer 5--8 kg. After every 5--10 days pouring water optionally, with a secondary barrier to water pouring fertilizer, applied per acre may be irrigated with Manyuanchun biological fertilization 10 kg. To ensure continuous high yield of cucumber. Fertilize later. With the harvest of cucumber, nutrient consumption continue, the need for stable and long nutrient supply, the latter ignored dressing, cucumber and premature aging due to lack of fertilizer, effectively shortening the harvest, cucumber production decline, increased bending melon melons and Other deformities. After 3 crop, Mushi urea 10 - - cucumber melon 220 kg female to reduce the development, promotion of cucumber "leading" growth, prevent deformity melon,
4 , the top of the top dressing. After the cucumber is planted, before flowering, at the beginning of the cassava, and at the beginning of the squash, the roots are topdressed. Each acre is sprayed with 2 bags of water and 30 kilograms of water in the garden to prevent premature aging and reduce deformity. melon.
