A kind of compound preparation of controlling and supplementing peanut at seedling stage and its application method

Abstract

The invention discloses a peanut seedling stage control and supplementary integrated composite preparation and a using method thereof. The composite preparation is prepared from, by weight, 30-40 parts of wettable powder containing 5% of uniconazole, 15-20 parts of water dispersible granules containing 10% of difenoconazole, 15-20 parts of ammonium molybdate and 20-30 parts of boric acid. According to the composite preparation, the effective component uniconazole can effectively control the basal internode length and the plant height of peanuts, the peanut plant height is decreased by 20.0%-28.3%, basal internodes are shortened by 25.9%-43.0%, uniconazole also can control damage of a low-light environment to the chloroplast structure of peanut leaves, and the leaf spad value is increased by 12.3%-15.4%; difenoconazole can prevent and control occurrence of peanut diseases; by applying molybdenum fertilizer in the seedling stage, growth of root nodules can be promoted, and the root nodule number is increased by 18.3%-39.4%; boric fertilizer can promote flower bud differentiation and flowering and needle penetrating, and the fruit needle number is increased by 12.5%-34.1%.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a compound preparation integrating control and supplementation at the seedling stage of peanuts and a use method thereof. Background technique [0002] The current peanut chemical control technology is aimed at single-cropping peanut fields. It is generally implemented in the middle and late stages of growth, when the peanut plant height reaches a certain standard, which can effectively control excessive growth and prevent premature aging and lodging in the later stage. However, for intercropping peanuts and intercropping peanuts, the excessive growth mainly occurs at the seedling stage, and the peanuts are affected by shading during the symbiotic period. When the peanut plant height reaches a certain standard, when chemical control is implemented, the main stem grows fast, the side branches develop slowly, the stems and branches are tender, and the base is nodular. ...

AI Technical Summary

Problems solved by technology

[0003] For the intercropping peanuts and intercropping peanuts existing in the prior art, the peanuts at the seedling stage are affected by shading, the main stem grows fast, the side branches develop slowly, the stems and branches are tender, the base internodes are long, and the chloroplasts of the leaves are damaged. The purpose of the present invention It aims to provide a compound preparation that integrates control and supplementation at the seedling stage of peanuts and its use method. While controlling the height of the plant and maintaining the integrity and normal shape of the chloroplast structure of the leaves, it can effectively prevent the occurrence of diseases at the seedling stage of peanuts, and provide needles for the growth of root nodules and flowering. Provide timely and necessary nutritional support
