Modifier for increasing production of corns and rice

Abstract

The invention discloses a modifier for increasing production of corns and rice, which contains forchlorfenuron, gibberellin and salicylic acid and the like. The medicaments are uniformly mixed according to a certain ratio under a room temperature drying environment. An increasing agent solution is sprayed in a later stage of flowering of rice and corns or a filling stage. The modifier can promote cell growth and division and the synthesis of nucleic acid and protein, and delay the organ abscission, crop senescence and chlorophyll synthesis. The photosynthetic rate is improved and the stress resistance is enhanced. The apical dominance is broken, the fruit setting is promoted and the fruits are amplified, and the parthenocarpy is induced, so that the crops are matured for 7-10 days in advance. The yields of rice and corns are increased by above 10%. The modifier is nontoxic and harmless, safe and reliable, low in cost, convenient to use and easy to operate.

Description

technical field [0001] The invention belongs to crop yield increasing technology, in particular to a corn and rice yield increasing regulator. [0002] Background technique [0002] At present, domestic and foreign products that increase the production of rice and corn can be divided into the following categories. Rice yield-increasing agents: (1) Cytokinin: Seeds can be soaked for 48 hours, washed repeatedly with clean water, conventional germination method, and then transplanted to the field, which can increase by 8.78%. Foliar spraying and spraying at the seedling stage can increase production by about 8%. Since the paddy field is not easy to pass through in the seedling stage, spraying is time-consuming and labor-intensive, and it is easy to cause damage to the seedlings. (2) Gibberellin: spraying at the seedling stage can increase the height of tiller plants, increase the number of tiller spikes, increase the seed setting rate, and increase yield by 6.97-7.6%....

Problems solved by technology

However, it cannot be mixed with alkaline pesticides and fertilizers when used, and the dosage should be strictly controlled below 100 g / mu

From the above analysis, it can be found that most of the existing regulators for increasing corn and rice production are single-type products, and sometimes they need to be sprayed multiple times, which is time-consuming and labor-intensive, with a large dosage and high input costs. Toxicity, resulting in difficult operation and dangerous implementation; and it also has requirements for the growth of crops, requiring higher field management techniques and more fertilizers
