Planting method for cultivating strong root systems of cucumber seedlings

Abstract

The invention discloses a planting method for cultivating strong root systems of cucumber seedlings. The method comprises the following steps of: firstly cultivating seedlings of cucumbers normally, pulling the seedlings out when the cotyledon is unfolded and the core leaf is 0.5 cm high, aligning by taking the cotyledon as reference, wherein one beam comprises 20-30 seedlings; cutting the seedlings at 5 cm low of the cotyledons by using a disinfected sharp cutter, dropping rootstocks and root parts thereunder, dipping vulnus with sterilization root accelerating liquid for 10 s in five minutes; then placing the root in active carbon which is crushed and passes through a 180-mesh sieve, is heated to 40-50 DEG C for 30-40 minutes, then planting the seedlings in a planting container; keeping the temperature at 22-24 DEG C in the day and 18-20 DEG C at night, pouring thin fertilizer after 3 days, and transplanting to the planting fields when the seedlings have one core with three leaves. The planting method for cultivating strong root systems of cucumber seedlings is used for converting the cucumber seedling from primary tap root systems to fibrous root systems, enabling the root system to be developed; therefore, the capability of absorbing fertilizers and drought resistance are stronger than that of the traditional seedling, the acute physiological withering does not exist easily; the fruit-setting peak period is 7-10 days longer than the normal planting method, thus the yield is increased for more than 15%.

Description

technical field [0001] The invention belongs to the technical field of cucumber cultivation, and in particular relates to a cultivation method for cultivating strong root systems of cucumber seedlings by cutting off the roots of cucumber seedlings and then planting them. Background technique [0002] Cucumber is an important global popular vegetable, and its cultivated area is second only to tomato, cabbage and onion, ranking fourth. Among them, about 241,000 hectares of cucumbers are cultivated in China, accounting for 28% of the world's cultivated area, ranking first in the world. In protected cultivation in northern my country, cucumber ranks among the best because of its high yield, remarkable economic benefits and stable market price. The folk proverb "If you want to get rid of poverty, build a greenhouse, and if you want to have money to spend, quickly grow cucumbers" reflects the status of cucumbers in protected vegetable cultivation. [0003] In recent years, with ...
