With the continuous improvement of the living standard of people, the dietary structure of people gradually develops towards green and pollution-free coarse food grains, and at present, the intake and the occupation of the coarse food grains are taken as the standard for measuring whether the dietary structure is healthy or not. Corn is a coarse grain product which is popular in people's daily life, especially sweet corn, because sweet corn can be used as vegetable and fruit.
Sweet corn (Sweet corn) Is a variety of corn, also called vegetable corn, gramineae and zea. Sweet corn is one of the major vegetables in developed countries such as europe, america, korea, and japan. It is a type that differs from other maize by the presence of one or several genes. Sweet corn is one type of vegetable corn. The sweet corn has high sugar content, sweet taste, high digestibility and rich nutrition, and is popular among people. Therefore, in recent years, the economic benefit of planting the sweet corn is higher and higher, and the popularization strength is also higher and higher. The sugar content of sweet corn grains is higher than that of common corn, and because of the reason, the sweet corn grains are easy to cause pests such as corn borers, scarab beetles, aphids and the like, if the sweet corn grains are not properly controlled, the quality is reduced, the yield is greatly influenced, and the economic benefit is seriously damaged. The current method for preventing and controlling the sweet corn diseases and insect pests mainly comprises two methods of using chemical pesticides and inoculating trichogramma egg blocks, wherein the chemical pesticides are used to easily generate pesticide residues, the human organs are seriously damaged after people eat the trichogramma egg blocks, the diseases and insects can generate gene mutation after long-term use to generate drug resistance, the corn yield can be reduced, the method for inoculating the trichogramma egg blocks only has certain effect on the corn borers, the inoculation is greatly influenced by weather, the one-time inoculation is often unsuccessful, and the ecological balance can be damaged for a long time. Therefore, a safe and efficient formulation for controlling corn pests is needed.

Used as an agricultural plant growth stimulant. Ethephon is a high-quality and high-efficiency plant growth regulator and has the effects of promoting fruit ripening, stimulating wound flow, regulating sex transformation and the like. Enters the plant body through the leaves, bark, fruits or seeds of the plant and then conducts to the site of action. Can promote adventitious root formation, make stem stout, plant dwarfing, relieve dormancy, induce flowering, control flower organ sex differentiation, mature fruit, promote aging and drop off.
The jasmine flower residue is obtained by separating jasmine flower scented tea. At present, a small part of jasmine flower residues in China are used as animal feed, and most jasmine flower residues are directly discarded, so that a large amount of waste and environmental pollution are caused. The jasmine flower residue contains a large amount of chemical substances which are beneficial to human bodies and can be developed and utilized, such as polysaccharide, flavone, essence oil and the like, and the jasmine flower residue can also be used for brewing wine and preparing organic fertilizers or animal feeds and the like. At present, the planting area of the jasmine flowers in China is about 12 ten thousand mu, the annual yield of the fresh flowers is about 9 ten thousand tons, and the annual yield of the jasmine flowers is stable between 11 and 12 ten thousand tons. The large jasmine tea yield is bound to be the yield of a large amount of jasmine flower residues, and researches show that the main chemical components of the jasmine flower residues after the jasmine tea is prepared are not changed, so that the jasmine flower residues can replace part of jasmine flowers to extract the chemical components. According to the determination, the jasmine flower residue contains a plurality of components such as abundant aromatic substances, flavones, polysaccharides and glycosides, and the chemical components can be applied to the industries such as medicines, foods, cosmetics and the like, and have high economic value.
