What's the yield on an acre of sweet corn? Planting time and technology should be clear!

Compared with ordinary corn, sweet corn is sweet, fresh, waxy and nutritious, no matter steaming, roasting or cooking. Besides internal friction, it is also exported, so it can be planted widely. What is the income of that kind of sweet corn per mu? What is the planting time and technology?

I. the basic situation of sweet corn

1. Distribution of sweet corn

Sweet corn is a kind of corn, also known as vegetable corn, is a type of vegetable corn. It is one of the main vegetables in Europe and the United States, South Korea, Japan and other developed countries, and it is planted in most parts of our country.

two。 The value of sweet corn

Corn is rich in vitamins, proteins and trace elements. Often eaten, it has the functions of lowering blood pressure, preventing cancer, detoxification, delaying aging, lowering serum cholesterol and preventing skin lesions. Sweet corn also has the function of medical and health care. Because it contains a variety of vitamins and minerals, it has the characteristics of fruits and vegetables. Contains unsaturated fatty acids, which can reduce cholesterol in the blood, soften blood vessels and prevent and treat coronary heart disease.

3. Corn planting subsidy

Han Changfu, minister of agriculture and village, said at the two national conferences that producers of corn and soybeans will be subsidized this year. The continued implementation of corn planting subsidies. In addition, in 2019, Heilongjiang Province will continue to implement the subsidy policy for corn and soybean producers, and appropriately raise the standard of corn producer subsidies on the basis of the previous year. Soybean producer subsidies per mu are more than 200 yuan higher than corn producer subsidies. Soybean producers subsidize about 300 yuan per mu.

The specific subsidy standard is determined by Heilongjiang Province according to the total subsidy funds of corn and soybean producers and the legal actual planting area of corn and soybean issued by the state.

What is the income from planting sweet corn on one mu of land?

1. Sweet corn can generally grow 2-3 crops in the south. For example, Datian County in Fujian Province can plant spring, summer and autumn corn with a cost of 630-710 yuan per mu.

two。 The purchase price of sweet corn is 1-1.40 yuan per jin, the total income in a year is 8900-9200 yuan, and the net profit excluding cost is about 6900-7200 yuan.

III. Planting time and technology of sweet corn

Sweet corn has wide adaptability and high planting efficiency, and is deeply loved by consumers, but to get better benefits, you must know the planting time and technology.

1. Planting time of sweet corn

The best way to plant sweet corn is to choose varieties with wide market, high yield, high quality and strong resistance, and sow them in mid-late March in spring or before early July in autumn, so that the yield of sweet corn per mu can reach more than 2000 jin.

two。 Planting techniques of Sweet Corn

The main results are as follows: (1) the fertile vegetable garden was selected to raise maize seedlings, and 40 pieces of 100-hole seedling tray per mu were laid on the whole seedbed. Early spring seedling cover agricultural film insulation, summer and autumn seedlings covered with sunscreen sunscreen moisturizing, after the emergence of 2 leaves, remove the sunshade net.

(2) transplant the successful maize seedlings to the upland fields with high soil fertility and convenient drainage and irrigation, and the paddy fields planted should be carefully prepared and applied sufficient amount of base fertilizer.

(3) when the maize seedlings have been sprayed with herbicides, they can be planted directionally when the seedlings have 4 leaves (the leaves should be perpendicular to the rows), and the whole seedling can be guaranteed by drenching enough water after planting. In addition, the density is kept at large row spacing of 80 cm, small row spacing of 50 cm and plant spacing of 25-30 cm.

(4) during the period of corn planting, 70% of the soil water holding capacity should be irrigated during drought, and horse water should be irrigated once in the flowering period; seedling raising fertilizer should be applied after planting, and jointing fertilizer and foliar fertilizer should be applied in combination with ploughing and weeding when growing 8-9 true leaves. Then apply grouting fertilizer according to the situation.

(5) in addition, attention should be paid to the prevention and control of diseases and insect pests such as ground tiger, mole cricket, green worm and corn leaf spot, and different pesticides should be selected according to the actual situation, but it should be remembered that the use of pesticides is prohibited 20 days before harvest.

Sweet corn has a wide range of uses, good prices, planting subsidies, so the choice of this project is still very good, the majority of growers should always pay attention to market changes, do not blindly expand and reduce production.
