Greenhouse horned melon fertilizing method

Abstract

The invention discloses a greenhouse horned melon fertilizing method. The fertilizing method comprises the following steps: (1) soil treatment before planting; (2) preparation of a controlled release fertilizer; (3) leaf fertilizer applying during a flowering period; (4) fertilizer applying in a young fruit formative period; (5) fertilizer applying in a fruit maturity period; during the preparation of the controlled release fertilizer, no waste gas, waste water and rubbish generate and the environment is not polluted, since the production process is simple without needing special equipment, the cycle is short, the cost is low, and the product price is equivalent to that of urea, the chemical fertilizer utilization is high, and the fertilizer-saving effect is outstanding, the sustained and controlled efficiency of the fertilizer is improved through coating, during different growth periods of horned melons, the way of foliage spraying or the way of combining foliage spraying with flushing and root drenching is adopted for supplementing nutritional ingredients required by the horned melons during different growth periods, and meanwhile, a fertilizing way is combined to improve the nutrition absorption in the earlier and later stages of the horned melons; the balanced combined application of nitrogen, phosphorus and potash fertilizers during horned melon production is well realized, and the fertilizer efficiency of the nitrogen, phosphorus and potash fertilizers is brought into full play.

Description

technical field [0001] The invention relates to the technical field of fertilization, in particular to a method for fertilizing horned melons in greenhouses. Background technique [0002] Horned melon is an annual herbaceous vine (climbing), which has three major strains: semi-climbing, dwarf and trailing. It is native to southern North America and is now widely cultivated. Sowing and reproduction, spring sowing or autumn sowing, spring sowing is the main method. Cultivation methods include open field, simple ground covering, protected cultivation (also divided into small shed and greenhouse cultivation), etc., each with its own characteristics. Here is a brief introduction to the general cultivation method: Seed selection and soaking: Remove debris, select clean and plump seeds with a thousand-grain weight of about 200g, put them in a pot or other oil-free container, soak them in cold water first, and then use warm water at 50-55°C Blanch the seeds, stir constantly, keep ...

Problems solved by technology

[0004] In the traditional method of fertilizing horned melons in greenhouses, the soil fertility is not good enough, so that the horned melon trees cannot obtain the various nutrients needed for their growth in a sufficient and balanced manner, which adversely affects the growth of horned melon shoots, flowers, fruits, etc. Fruit yield and quality are not good, which is not conducive to increasing production and income of fruit farmers

In addition, the use of root fertilization will often cause uneven fertility in the soil, and it is easy to cause fertilizer loss. Moreover, the absorption rate of nutrients by the horned melon tree is slow and the absorption efficiency is low.
