A kind of cultivating method of broad bean vernalization matrix seedling

Abstract

The invention provides a method for cultivating broad bean substrate seedlings. The method comprises the following steps: soaking and disinfecting seeds, packing and sowing seeds, stacking trays in a low-temperature treatment bank, low-temperature vernalization treatment, seedling cultivation, and planting. The method uses substrates to cultivate vernalized seedlings. Compared with the original vernalization method for bud treatment, the poison of viscous substances to broad beans during the treatment process is reduced, the damage to broad bean sprouts is reduced, the emergence rate is increased by more than 5%, and the fresh weight of rice seedlings is increased. More than 10%, the dry weight of rice seedlings increases by more than 3%, which greatly improves the quality of rice seedlings. Compared with the original vernalization method for seedling treatment, the process is simplified and the problems of low root system activity and easy dead seedlings are solved. The seedling rate is increased by more than 15%, and the incidence rate is reduced by more than 15%.

Description

technical field [0001] The invention relates to the field of broad bean planting, in particular to a method for cultivating broad bean vernalized substrate seedlings. Background technique [0002] "Vernalization" refers to the phenomenon that plants must go through a period of continuous low temperature to change from the vegetative growth stage to the reproductive stage. Most winter annual or biennial plants must go through a certain period of continuous low temperature in their seed germination period or early vegetative growth period to flower and set fruit. [0003] The current vernalization treatment technology of broad bean can be divided into two types: bud low temperature treatment and seedling low temperature treatment. CN102652484B discloses a "fresh broad bean vernalization treatment method" which is low-temperature treatment of buds. The specific operation is to put the seeds into a plastic basket and wash them with clean water, cover them with double-layer gauz...

Problems solved by technology

[0004] In order to solve the problems of broad bean stickiness caused by harmful substances produced in the vernalization process of broad beans, easy damage to broad bean sprouts during sowing, low root activity, and easy death of seedlings, the invention provides a broad bean vernalization substrate for cultivating robust vernalized seedlings A seedling cultivation method, the method may further comprise the steps:
