Problems solved by technology

However, if the environmental temperature and humidity are not controlled correctly, such as rainy weather after sowing, insufficient light, and low temperature for too long, etc., it is easy to cause mildew and no germination or low germination rate of hybrid seeds; In continuous high temperature weather, it is necessary to use spraying and watering in time to cool down and increase humidity based on experience, but it is easy to water not in time or excessive or uneven watering, which may easily cause hybrid seeds to not sprout or rot.

Embodiment 1

[0035] Embodiment 1 A kind of accelerating germination method that improves sugarcane hybrid seed germination rate

[0036] Including the following steps:

[0037] (1) Preparation of seedling substrate: select cultivated soil (local paddy field soil) and sieve it with a 10-mesh or 12-mesh sieve to remove large particles or inclusions. The cultivated soil is turned and watered once a week, and turned 3-4 times continuously. After each turning, the surface layer is exposed to water, so that the weed seeds in the soil can germinate quickly and remove the weeds. The prepared tillage soil, peat soil, and vermiculite were mixed according to the mass ratio of 3:1:0.5 and used as the seedling raising substrate.

[0038] (2) Seed sowing: at the end of March or early April, put the seedling substrate prepared in step (1) in the seedling box, flatten, compact, and pack to 2 / 3 of the seedling box, with a thickness of 4-6cm. According to the germination rate of sugarcane hybrid seeds, di...

[0040]Embodiment 2 A kind of accelerating germination method that improves sugarcane hybrid seed germination rate

[0041] Including the following steps:

[0042] (1) Preparation of seedling substrate: select cultivated soil (local paddy field soil) and sieve it with a 10-mesh or 12-mesh sieve to remove large particles or inclusions. The cultivated soil is turned and watered once a week, and turned 3-4 times continuously. After each turning, the surface layer is exposed to water, so that the weed seeds in the soil can germinate quickly and remove the weeds. The prepared tillage soil, peat soil, and vermiculite are mixed according to the mass ratio of 4:1.5:0.7 and used as the seedling raising substrate.

[0043] (2) Seed sowing: at the end of March or early April, put the seedling substrate prepared in step (1) in the seedling box, flatten, compact, and pack to 2 / 3 of the seedling box, with a thickness of 4-6cm. According to the germination rate of sugarcane hybrid seeds, di...

[0045] Embodiment 3 A kind of accelerating germination method that improves sugarcane hybrid seed germination rate

[0046] Including the following steps:

[0047] (1) Preparation of seedling substrate: select cultivated soil (local paddy field soil) and sieve it with a 10-mesh or 12-mesh sieve to remove large particles or inclusions. The cultivated soil is turned and watered once a week, and turned 3-4 times continuously. After each turning, the surface layer is exposed to water, so that the weed seeds in the soil can germinate quickly and remove the weeds. The prepared tillage soil, peat soil, and vermiculite are mixed according to the mass ratio of 2:0.5:0.3 and used as the seedling raising substrate.

[0048] (2) Seed sowing: at the end of March or early April, put the seedling substrate prepared in step (1) in the seedling box, flatten, compact, and pack to 2 / 3 of the seedling box, with a thickness of 4-6cm. According to the germination rate of sugarcane hybrid seeds, d...

Abstract

The invention belongs to the technical field of crop cultivation, and in particular relates to a germination accelerating method for increasing the germination rate of sugarcane seeds and an application thereof. In order to provide a germination accelerating or seedling raising method capable of increasing the germination rate of sugarcane seeds, the invention provides a method for increasing the germination rate of sugarcane seeds The method for accelerating germination is to build a film shed on the seedling substrate of sowing sugarcane seeds, then transfer it to the cultivation greenhouse, and cultivate it for 3-5 days under certain conditions. Using this method to accelerate the germination of sugarcane seeds can promote the growth of sugarcane hybrid seeds. Germination, high germination rate, fast and neat emergence; applied to the cultivation of sugarcane seedlings, the quantity and quality of each hybrid combination sugarcane seedling population can be guaranteed; at the same time, the sowing time of the germination accelerating method provided by the invention is not affected by the external environment. influences.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a germination accelerating method for increasing the germination rate of sugarcane seeds and an application thereof. Background technique [0002] Sugarcane (Saccharum officinarum L.) is the most important sugar crop in my country, mainly distributed in southern regions such as Guangxi, Yunnan, Guangdong, and Hainan. At present, the process of breeding new sugarcane varieties is mainly to obtain hybrid seeds through conventional cross-pollination methods, grow the obtained hybrid seeds to obtain seedlings, then transplant the cultivated seedlings to the field, and finally pass the pedigree selection method or family selection method. Perform system screening. Since sugarcane is an allopolyploid plant with a very complicated genetic background, breeders need to sow tens of thousands to hundreds of thousands of seedlings every year for selection. Therefore, t...
