Seed soaking agent capable of cultivating multi-tiller robust seedlings of rice and use method thereof

Abstract

The invention discloses a seed soaking agent capable of cultivating multi-tiller robust seedlings of rice and a use method thereof. The seed soaking agent comprises the components in percentage by weight: 30-100 percent of uniconazole, 0.025-0.10 percent of brassinolide and 0.1-0.5 percent of S-abscisic acid, and further comprises certain percentage of ClO2. During use, an aqueous solution is adopted for the seed soaking agent, in which the uniconazole is 30-100mg / L, the brassinolide is 0.025-0.10mg / L, the ClO2 is 100-200mg / L and the S-abscisic acid is 0.1-0.5mg / L; the weight ratio of rice seeds to the seed soaking agent aqueous solution is 1: (1-2). The seed soaking agent disclosed by the invention can enable the rice seeds to sprout robustly and healthily; seedlings grow after sprouts are adjusted and controlled; tillering in a seeding stage is promoted; during seedling generation, the seedlings are stocky and have multiple tillers, and the roots are developed; after being transplanted, the seedlings are high in re-greening speed and are rooted and tillered early; the seed soaking agent is suitable for robusting the seedlings of rice cultivated in a paddy field in China.

Description

technical field [0001] The invention relates to the field of plant growth conditioners, in particular to a seed soaking agent for cultivating multi-tiller and strong seedlings of rice and a method for using the same. Background technique [0002] Cultivating rice with multiple tillers and strong seedlings and promoting early growth after planting is the basis for high rice yield. In the main rice growing areas in my country, especially the double-cropping rice growing areas in the middle and lower reaches of the Yangtze River, the continuous cropping of late rice is limited by stubble openings, and the temperature of early rice seedlings is low, which is easy Cause low temperature and chilling injury; while the seedling age of late rice is relatively long, and seedling raising is in midsummer, the seedlings grow rapidly, and the seedlings are too large when transplanted, and the seedlings are defeated and delayed after planting, delaying the season and affecting the yield. Tw...

AI Technical Summary

Problems solved by technology

The reform of seedling raising and transplanting technology has become the focus of rice farming innovation, among which machine transplanting and throwing seedlings have very high requirements on the quality of seedlings, and traditional seedling raising technology is difficult to meet the new requirements

[0004] In addition, the low temperature in the early rice seedling raising period requires nylon covering, and the high temperature in single or continuous late seedling raising often causes bakanae disease and excessive growth.
