Problems solved by technology

If the spraying concentration is too high, the growth of the plant will be excessively inhibited, and obvious phytotoxicity will be formed, showing that the plant is short, stiff seedlings are formed, the growth is slow, no ear can be drawn, the ear is deformed, the seed setting rate is reduced, and the yield is reduced.
[0006] my country has a wide range of rice planting areas, with various varieties and various planting periods. Due to the short time on the market of prohexadione calcium, the lack of detailed application

Abstract

The invention belongs to the field of agricultural chemistry, and specifically relates to a paddy rice growth regulator composition containing prohexadione calcium and rare earth nitrate. The effective components of the composition are prohexadione calcium and rare earth nitrate. The mass ratio of prohexadione calcium to rare earth nitrate is 1:1-1:100. The composition also comprises non-effectivecomponents. The effective components account for 1.5 to 95% of the weight of the composition. Prohexadione calcium accounts for 0.5 to 25% of the total weight of the composition. Rare earth nitrate accounts for 1 to 70% of the total weight of the composition. The composition can solve the problem that paddy rice is damaged by pesticide due to incorrect application time or incorrect using amount.Prohexadione calcium and rare earth nitrate are used together so as to buffer the effect of prohexadione calcium.

Description

Technical field [0001] The invention belongs to the field of agrochemicals, and specifically relates to a rice growth regulator composition containing calcium regalicum and rare earth nitrate. Background technique [0002] Calcium regex is a new plant growth regulator. The synthesis of gibberellin can be inhibited by absorption by plant seeds, roots and leaves. It can shorten the elongation of the stem of many plants, control the growth of the end of the crop, make the stem thick, dwarf the plant, reduce and prevent lodging; promote growth, promote the growth of lateral buds and root, keep the stems and leaves dark and the leaves stand upright ; Control flowering time, increase fruit setting rate, and promote fruit maturity. It can also improve the stress resistance of plants and enhance the ability of plants to resist diseases, cold and drought. Compared with the currently widely used triazole retarders, the calcium fortunet has no residual toxicity to rotation plants and no ...
