Background
The serious year-old fruiting phenomenon is common in the production of the waxberries, so that not only is the market supply relation unbalanced, but also the economic income of fruit farmers is seriously influenced due to the reduction of the fruit quality caused by the year of the year. Currently, chemical flower thinning agents and flowering agents are mainly used for regulating and controlling the annual output, and increasing the annual output so as to keep the output basically stable. The chemical flower and fruit thinning almost replaces the artificial flower and fruit thinning, and has the characteristics of labor saving, time saving, low cost, high speed and suitability for large-area intensive production compared with the artificial flower and fruit thinning. However, the chemical flower thinning agent mainly comprises some artificially synthesized plant hormones such as naphthylacetic acid, paclobutrazol, ethephon, 6-benzyl adenine, some pesticide preparations and the like, has long residual time, has certain food safety risks, is gradually challenged by consumers, and does not meet the increasing food safety requirements of people. Furthermore, the sensitivity of different fruit tree varieties is different, and various fruit trees and crop phytotoxicity events are endless. In view of the above, the chemical flower thinning agent has the advantages of low development cost, time and labor saving, no toxicity and harm to people and animals, safety to flower-visiting insects and no pollution to the environment, and is one of the important research subjects at present.
The alligator alternanthera Alternanthera philoxeroides (Mart.) Grisea is a plant of the genus Alternaria of the family Amaranthaceae, is native to south America, is now a global malignant weed, and is widely distributed in the provinces of Hebei, jiangsu, zhejiang, fujian, jiangxi, guangxi and the like in China. The existing researches show that the whole herb of the Chinese herbal medicine has the effects of clearing heat, promoting diuresis, cooling blood, removing toxicity, and has a certain chemosensory effect, and can inhibit seed germination and growth under the condition of specific concentration; it is notable that it is also a high potassium plant that can be used as a source of high-efficiency potash fertilizer. In view of the above, it is urgent to develop natural, environment-friendly agents with flower thinning effect suitable for bayberry. The invention surrounds the aim, is based on nontoxic and harmless traditional Chinese medicine components to be compounded into the pollution-free flower thinning agent, and has obvious effect on adjusting the size of the waxberry result.
Disclosure of Invention
The invention aims to provide a pollution-free Yang Meishu flower agent.
In order to achieve the above purpose, the invention adopts the following technical scheme:
a nuisanceless Yang Meishu flower, comprising: alternanthera philoxeroides powder and ammonium acetate.
Preferably, the solvent of the flower thinning agent is water, and the concentration of ammonium acetate is 0.05-0.1mol -1 150-300g.L of alternanthera philoxeroides powder -1 。
Preferably, the flower thinning agent is applied by taking the supernatant after centrifugation or filtration. The flower thinning agent can be directly applied without filtration, but the spraying holes are easy to be blocked when the flower thinning agent is applied by tools such as a sprayer, so that the application after filtration is more convenient.
Preferably, the agricultural organic silicon synergist also comprises a surfactant. For plants with revolutionary surfaces of leaves such as waxberries, the sprayed flower thinning agent is not easy to wall, the flower thinning effect is affected, and after the surfactant is added, the flower thinning agent is beneficial to stay on the surfaces of the plants, so that a better flower thinning effect is achieved.
Preferably, the agricultural organosilicon synergist is diluted by 1000-1500 times and sprayed.
The invention also discloses a preparation method of the pollution-free Yang Meishu flower agent, which comprises the following steps:
pulverizing Alternanthera philoxeroides, adding into water, adding ammonium acetate, and soaking for more than 20 hr to obtain nuisanceless Yang Meishu flower preparation.
Preferably, the soaking is carried out for every 2-6 hours.
Preferably, an agricultural organosilicon synergist is also added.
Preferably, the addition amount of the alternanthera philoxeroides is 150-300g.L -1 The addition amount of ammonium acetate is 0.05-0.1mol.L -1 。
Preferably, the addition amount of the agricultural organic silicon synergistic agent is 0.67-1.0ml -1 。
Preferably, after soaking, centrifuging or filtering with gauze, and collecting supernatant to obtain nuisanceless Yang Meishu flower.
The invention also discloses application of the pollution-free Yang Meishu flower agent in reducing the fruit setting rate of waxberries.
Preferably, the excessive flowering plants of the waxberries which enter the later stage of flower filling and have no plant diseases and insect pests and normal growth and development of leaves are selected, the flower thinning agent is uniformly sprayed on the crowns of the whole plants at least twice, and the time interval between the spraying of the flower thinning agent and the spraying of the water thinning agent is 72 hours after the spraying of the flower thinning agent onto the crowns each time.
Preferably, the plant flower thinning agent is sprayed twice, and the interval time between the spraying of the plant flower thinning agent and the spraying of the plant flower thinning agent is 72 hours.
Notice that:
1) The waxberry flower thinning agent can be used only under the condition of excessive flowering, and can be used under the condition that the leaves of the waxberry plants grow healthily.
2) The spraying time of the waxberry flower thinning agent is important, and the waxberry flower thinning agent is suitable for the young fruits with the size of a matchhead at the end of Yang Meicheng flowers, and is used in continuous sunny windless weather during spraying.
Compared with the prior art, the invention has the beneficial effects that:
1) The flower thinning agent of the invention mainly comprises Chinese herbal plants, namely alternanthera philoxeroides and ammonium acetate which can be used as food additives, does not contain any artificial synthetic hormone, and is green, environment-friendly and pollution-free. In view of the fact that alternanthera philoxeroides is an invasive malignant weed, the alternanthera philoxeroides is gathered in pieces worldwide, and huge losses are caused to agricultural irrigation, aquaculture, grain transportation and travel. It can kill the higher plants in water, eliminate aquatic animals and destroy ecological balance in water area. The invention provides a new idea for reducing the pressure of the alternanthera philoxeroides on the ecological environment based on the purpose of comprehensive development and effective utilization of the alternanthera philoxeroides by local materials.
2) The flower thinning agent disclosed by the invention has the advantages that the components of the flower thinning agent are all water, the materials are convenient to obtain, the ammonium acetate is used as a strong electrolyte inorganic salt, the aqueous solution is neutral in acid-base, and the pollination fertilization of the gynoecia of the waxberry can be effectively inhibited. Wherein, acetate can promote the synthesis of plant hormone jasmonic acid, thereby improving the stress resistance of plants; ammonium ions belong to foliar fertilizers, and can effectively improve photosynthesis capacity of plant leaves under the condition of specific concentration; in addition, the ammonium acetate solution can help to dissolve and release bioactive substances and potassium elements of the alternanthera philoxeroides for plant absorption and utilization, and the two components complement each other, so that the alternanthera philoxeroides is safe and efficient and has no side effect.
