Simple asparagus lettuce seed germination method

Abstract

The invention discloses a simple asparagus lettuce seed germination method which comprises the following steps: S1, asparagus lettuce seeds are finely selected, bagged, then directly placed in a freezer (-20DEG C) for low temperature treatment for 2 days and nights, and directly sowed; S2, because the asparagus lettuce seeds are germinated under light, before sowing, a seedbed must be watered completely, after sowing, the asparagus lettuce seeds are covered with a thin layer of soil or matrix. The cost (hormone cost and instrument cost) in the prior art can be avoided, to be most important, unsoaked asparagus lettuce seeds are dispersed individually, and are easy to sow, and labor force can be effectively reduced.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a simple method for accelerating germination of lettuce seeds. Background technique [0002] The suitable temperature for germination of lettuce seeds is 15-20°C. If the ambient temperature exceeds 30°C, the high temperature will directly hinder the germination of the seeds, which has a phenomenon of thermal dormancy, and these seeds need light to germinate, which are called light-requiring seeds or photosensitive seeds. When sowing lettuce in summer and early autumn, it must be treated before sowing. [0003] Existing technologies or methods include: [0004] 1. Hormone germination method, first select the seeds, soak the seeds in 500ppm ethephon or 300ppm gibberellin and other hormone solutions that can improve the germination power of lettuce, after 6 to 10 hours, drain the water and spread it on wet gauze, indoors See light germination at natural high temperature. Usually 2 days...

AI Technical Summary

Problems solved by technology

[0006] The existing technology is slightly complicated. In method 1, hormones need to be purchased, which has a certain cost, and hormone solutions of corresponding concentrations need to be prepared, and the concentration of hormone solutions is generally relatively small. Weighing hormones requires a high-precision balance (high cost) , the hormone concentration directly affects the germination rate of lettuce, which is difficult for ordinary agricultural growers to operate; method 2 is a method that is widely used now, but both methods need to soak the seeds. As we all know, lettuce seeds stick to each other after soaking, It is not easy to separate, which brings great inconvenience to sowing, and is labor-intensive and time-consuming. At this stage, agricultural costs, including labor costs, remain high and tend to increase gradually
