Problems solved by technology

[0004] In order to solve the problems existing in the existing sugar beet planting technology, such as slow seedling emergence and uneven seedlings, which affect the management of the seedbed and cause the quality of the seedlings to decline, the invention provides a kind of initiator for improving the effect of sugar beet seedling emergence. The initiator A mixed initiator consisting of 0.5 mmol / L gibberellin or 0.5 mmol / L salicylic acid or 0.1 mmol / L gibberellin+0.1 mmol / L salicylic acid+0.1% PEG6000

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the examples, but the present invention is not limited to the following examples.

[0023] The experiment was carried out in the artificial climate chamber of the College of Modern Agriculture and Ecological Environment, Heilongjiang University in December 2019. Beet single-seed varieties 701, 703, 801, 802, and 805 were selected as test materials, which were provided by the beet fine variety breeding team of the College of Modern Agriculture and Ecological Environment, Heilongjiang University.

[0024] 1. Screening experiment of seed germination rate

[0025] Pretreatment the seeds first: take about 450 sugar beet seeds 701, 703, 801, 802, and 805 respectively, wash them with running water for 6 hours, soak them in 70% alcohol for 1 minute, wash them with distilled water for 4 times, and then use 8‰ thiram Soak in the double solution overnight, and rinse with distilled water several times the ne...

Abstract

The invention discloses an initiator for improving a beet seedling emergence effect and an application method thereof, and belongs to the technical field of crop planting. In order to solve the problems of seedling quality reduction and the like caused by influence on seedbed management due to slow seedling emergence and seedling irregularity in an existing beet planting technology, the following technical schemes are provided: 0.5 mmol/L gibberellin or 0.5 mmol/L salicylic acid or a mixture of 0.1 mmol/L gibberellin, 0.1 mmol/L salicylic acid and 0.1% PEG6000 composition is used as the initiator, and the aim of improving the beet seedling emergence effect is achieved through a paper tube seedling raising method. The initiator which is relatively low in cost and relatively good in seedling emergence effect after being treated is found; reference is provided for field production of beet and cultivation of beet paper tube seedlings; and the initiator is of very important significance.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to an initiator for improving the emergence effect of sugar beets and an application method thereof. Background technique [0002] Seed priming (seed priming) technology was first proposed in the seventies in the 20th century. It is a kind of pre-sowing seed treatment technology for carrying out physiological preparation in advance for seed germination. The seed priming technology is proposed based on the biological mechanism of seed germination. The purpose is to promote seed germination, increase the stability rate of germination time and uniform rate of germination, reduce the standard deviation of germination time, improve the resistance and quality of seedlings, and improve nutrition. situation. Initiation is mainly achieved through osmotic regulation, temperature regulation, gas regulation and hormone regulation. Its advantages are rapid germination, high e...
