A method for one-time collection and sowing of plant seeds at different maturity stages

Abstract

The present invention relates to the technical field of plant resources development and utilization, in particular to a one-time collection and sowing method of plant seeds at different maturity stages, which can not only collect early-maturing seeds in time but also ensure that late-maturing seeds can develop normally and reach commercial seeds under the technical conditions of the present invention. The standard is to make full use of the limited seed resources and effectively ensure the quality of the collected seeds. The principle is to remove the leaves of the branches bearing the seeds and keep the seeds on the branches together, and use the nutrients stored in the branches to track and continue to grow Give the immature seeds to continue to develop, and sow them in the wet sand treated with the ripening agent in time to accelerate ripening and germination.

Description

Technical field: [0001] The invention relates to the technical field of biological longitudinal cutting propagation, in particular to a method for collecting and sowing plant seeds at different maturity stages at one time. Background technique: [0002] Environmental ecology is inseparable from plants, and the reproduction of plants is inseparable from seeds. Due to people's excessive felling of plants, especially rare forest resources, the amount of plants has declined sharply, and people have not adopted scientific seed collection methods for the remaining forest trees, resulting in a shortage of plant seed resources. Therefore, how to scientifically and rationally collect and utilize limited plant seed resources and improve the quality of plant seeds is a very important issue in environmental ecology and sustainable development. [0003] When plant seed collectors collect seeds, they often encounter the practical problem of inconsistency in seed maturity. For example, it...

Problems solved by technology

[0003] When plant seed collectors collect seeds, they often encounter the practical problem of inconsistency in seed maturity. For example, it takes nearly a month for the seeds of the genus Runicola to mature from the earliest seeds to the latest seeds. caused great inconvenience

If the early mature seeds are not harvested in time, some of the mature seeds will be eaten by birds, squirrels, mice and other animals, some will fall to places where they cannot be collected, such as cracks in the ground and grass, and some will be dehydrated due to sun exposure Or rotten and deteriorated and unable to germinate, wasting precious seed resources in vain; if the earlier mature seeds and immature seeds are collected together, the seeds that have not developed to the commercial standard will not germinate at all, and the mature seeds will be affected by mildew. quality

If the method of one-time collection of seeds is adopted, the germination rate of the seeds is very low, and the waste rate is high, and most of the immature seeds are wasted; Bulk plant seed collection

[0004] In addition, ethephon is currently used in the market to accelerate ripening, but the quality of the ripened seeds decreases, which is not suitable for plant breeding
