Alpinia oxyphylla flower and fruit protectant and preparation method thereof

Abstract

The invention provides an alpinia oxyphylla flower and fruit protectant, which consists of the following components: 100mg to 150mg of phethalanilic acid, 0.005mg to 0.015mg of brassin, 10mg to 30mg of gibberellin and 10mg to 25mg of compound sodium nitrophenolate are contained in per liter of water. The phethalanilic acid, the brassin, the gibberellin and the compound sodium nitrophenolate are dissolved into water, and thereby the alpinia oxyphylla flower and fruit protectant is obtained. By a lot of experiments, the phethalanilic acid, the brassin, the gibberellin and the compound sodium nitrophenolate are chosen by the inventor, the proportion is optimized, the obtained flower and fruit protectant which is exclusively applicable to alpinia oxyphylla has a good flower and fruit protection effect, is capble of effectively increasing the fruit setting rate, the fruit setting rate can reach 59 percent, moreover, the components of the flower and fruit protectant are less, the cost is low, the raw materials are easy to purchase, and the preparation solution is simple and easy to operate, and therefore can be conveniently accepted by farmers and applied on a large scale.

Description

technical field [0001] The invention relates to a pesticide preparation for promoting growth of intelligence growth, in particular to a growth protection agent for growth improvement and a preparation method thereof. Background technique [0002] Yizhi belongs to Zingiberaceae, and Alpinia officinalis is a perennial herb. The plant height can reach 3 meters; the stems are clustered; the rhizomes are short, the leaves are lanceolate, the raceme is completely enclosed in a cap-shaped involucral bract when the flower bud is in flower, and the whole flower falls off, the inflorescence axis is covered with very short pilose; calyx Tube-shaped, white corolla, sparsely pilose outside; lip obovate, pinkish white with red veins, capsule spherical when fresh, spindle-shaped when dry, irregular oblate seeds, covered with light yellow aril. The fruit is oval, slightly pointed at both ends, brown or grayish-brown in surface, with longitudinally uneven protrusions. The pericarp is thin ...

AI Technical Summary

Problems solved by technology

Plant growth regulators increase the fruit setting rate by promoting the rapid thickening of the fruit stalk. When using it, the method of smearing the flower stalk and spraying the flower is mainly used. However, due to the difficulty in controlling the concentration, deformed fruit, cracked fruit, and stiff fruit are prone to occur. The flower method is more labor-intensive, so the usage rate is getting lower and lower

The mixed solution of nutrient elements and plant growth regulators is used by plant spraying method, which saves labor, time and high efficiency, but the addition of trace elements and / or pesticides increases the cost, which is difficult for some farmers to accept
