Sweet corn is a good nutritional health item and a variety of foods of good taste. Its advantages are high internal sugar content, high protein content and higher amino acid content than normal maize. Out a lot, almost twice. As a result, future trends in sweet maize are relatively good and attention should be paid to the development of the sweet maize industry. At this stage, the greatest advantages of sweet maize cultivation are choice of improved varieties, choice of plots, planting time and seedling management, and disease prevention and control. The main elements presented in this paper include research on cultivation techniques, which it is hoped will be improved to provide some input to most growers。
The purpose and significance of improved sweet maize cultivation techniques. Sweet corn is divided into three main types, with ordinary sweet corn, super sweet corn and enhanced sweet corn. The main type of cultivation in the country is super sweet corn. Sweet corn has its own advantages, and if farming techniques are simple, short-lived and have good economic benefits, its economic benefits are three times that of ordinary maize, twice as high as rice, and it has a certain preventive function, and therefore prospects for future development are excellent。
Selection of plots and improved varieties. Corn cultivation has its own characteristics and is not very demanding and adaptable, which is the key reason why maize can be grown extensively. Areas with better irrigated drainage conditions are selected, transport is easy to manage, and soil fertility is considered. Sweet corn seeds should be selected for disease-resistant varieties with good experimental effects. The selection of seeds allows for 2 〜3h exposure in sunlight and reverses to ensure that the seeds are evenly dry, immersed in cold water and washed with clean water. Corn is a light-efficient crop with good light co-operation, so the role of soil and light should be emphasized in order to improve the production and quality of maize。
Plantation and planting in a timely manner. The best time to choose the planting time is march of the year, followed by june to july of the year, with a life span of approximately 100 days. The problem of cold spring is one to be considered in early maize cultivation, so that if necessary, coverings are planted so that young seedlings are not exposed to spring cold. Land parcels should be selected with the following conditions, with a higher terrain and a richer sun. In addition, proper seed drying and leaching is required. Insulated with warm water, a certain percentage of mixed work is required, 4 〜6h piles are required and seeding will follow。
Sweet corn has certain requirements for sowing depth, not more than 3 cm in depth and not more than 4 cm in ordinary corn, but if you need to work on it, you need some treatment, i. E. Calcium and zinc on the face of the corn leaf, to ensure that the corn can grow well。
Cultivation and osmosis management. When sweet corn seedlings come out, if they are lacking, they should be replaced in a timely manner and, if they are more severe, replaced where they are not available. After sweet corn appears, when it grows to three leaves, it needs to be removed to ensure that the remaining seedlings grow well. If blades are of up to 5-6 units, care is also taken to apply fertilizers and to develop fertilisation plans on a case-by-case basis. In addition, weeding is done in a timely manner, which can improve the growth conditions of maize seedlings。
The most critical period of sweet maize production in the long term is the ostrich period, which is divided mainly into entry management and entry periods. , the festival begins until the title period, which is a critical period for the growth of sweet maize, during which a certain amount of water is required. If there is a shortage of water during this period, which has a direct impact on the growth of maize, this will have a direct impact on its production and quality. In addition, fertilizer supplementation should be carried out in a timely manner during the exercise. When sweet corn blooms, artificial pollination is possible under certain conditions, but you should choose the appropriate time。
The main pests for enhancing pest control and harvesting timing selection of sweet maize are aphids and cornbores. Especially in the long term, it should be cultivated to prevent and control it, and the critical period of control is the stage of progress and maturity, and the impact on the quality of sweet maize would be very severe in the case of cornbore. If harmful organisms are found, they should be treated in a timely manner. The colour of sweet corn must be observed before the sweet corn is harvested, and when corn silk turns brown, it is the best time to harvest, a period of high sweetness and, at the same time, better taste. After harvest, maize should be refrigerated, if not frozen, which would directly affect its sweetness. In addition, once the harvested maize is preserved, it may be sold under market conditions。
Conclusions. This paper provides a brief overview of the techniques used to grow sweet maize, along with a certain degree of analysis and, in the light of the current state of affairs, some high-yielding measures that are expected to inform a wide range of growers。
