Seedling exercising method for improving vigor of cucumber seedlings

Abstract

The invention discloses a seedling exercising method for improving the vigor of cucumber seedlings. The seedling exercising method comprises the following steps of 1 seedling exercising matrix preparing, 2 rooting nutrient solution preparing, 3 seedling transplanting and 4 managing after transplanting. According to the method, all the steps are scientifically and reasonably matched and accord with the growth rules of the cucumber seedlings, the management mode is more precise and more careful, the problem that the seedlings are prone to be damaged in a traditional mode is solved, and good universality and a greater guide value are achieved on the cucumber seedlings; the cucumber seedlings subjected to seedling exercising are thick and strong in root and stem, more nutritional substances are contained in the cucumber seedlings, the enzymatic activity related to the resistance is significantly promoted, the survival rate of the exercised seedlings reaches 99% or above, the survival rate of the seedlings which are planted in a field after being exercised reaches 98% or above, the quality of bred cucumber fruits is well promoted, the vitamin C content in the fruits is increased by 60%-70%, the calcium element content in the fruits is increased by 25%-35%, the fruit yield per mu is increased by 15%-20%, and very good economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a seedling hardening method for improving the vigor of cucumber seedlings. Background technique [0002] Cucumber is rich in nutrients, including protein, fat, carbohydrates, calcium, phosphorus, potassium, iron and other elements, vitamin C, carotene, caffeic acid, chlorogenic acid, a variety of free amino acids and volatile oil, cucurbitacin, cucumber enzymes, etc. , also contains ingredients that can inhibit the proliferation of cancer cells. Therefore, from a nutritional point of view, it is one of the vegetables that are very suitable for everyone to eat for a long time. [0003] Nowadays, when cucumbers are planted, seedlings are raised first and then planted. After seedlings are raised and before planting, it is usually necessary to harden the seedlings. The purpose is to make the seedlings better adapt to the external environment, enhance their resistance, and ensure ...

AI Technical Summary

Problems solved by technology

The existing seedling hardening methods are relatively rough, and whether the management of temperature, humidity, light and other factors is reasonable or not is usually judged by the growth of the seedlings. This method is likely to cause irreversible damage to the seedlings, thereby reducing the hardening effect. The hardening method takes a long time, usually about a week, and the quality of the hardened seedlings is uneven, and it will not significantly improve the quality of the fruit
