The latest course on planting techniques and methods of sweet corn

Sweet corn is a kind of corn, which is also very popular in our country. Sweet corn tastes sweeter and has a slightly higher nutritional value than ordinary corn. So now there are a lot of people growing sweet corn, but the planting method of sweet corn is different from ordinary corn. So how to grow sweet corn? The following editor brings you the planting technology of sweet corn, let's have a look!

1. Isolated planting

When planting sweet corn, we need to be isolated from ordinary corn, and the distance between them should be kept at about 400 meters. Isolation planting is divided into spatial isolation and time isolation, most of which are mainly spatial isolation. However, no matter what the isolation method is, it is mainly to ensure that the pollen of the two kinds of corn will not meet. When planting sweet corn, we should also pay attention to the selection and preparation of land. Under the premise of ensuring soil moisture, the soil should be ploughed and ploughed. Keep the soil fine, empty and solid, and because the grain of sweet corn is not full, the top soil capacity of the top bud is relatively poor, so sowing should not be too deep to ensure the whole seedling.

2. Planting density

When determining the planting density, attention should be paid to the control according to the variety characteristics, climate and water and fertilizer management of sweet corn. Because sweet corn itself belongs to a commodity, we should also pay attention to the product characteristics of the ear. Can not just focus on the yield, because the ear is to be graded acquisition. Generally speaking, it is mainly based on export processing, so we should improve the rate of first and second grade products as much as possible. At the same time, it is necessary to adjust the planting density according to the requirements of commodities and economic benefits to ensure the economic income per unit area.

3. Seedling mulching

The economic benefit of sweet corn is closely related to its time to market. It has the same characteristics as some common vegetables, for example, in the north, if the fruit can be put on the market during the off-season, then its economic benefits will naturally be improved. If you want to control the time to market of sweet corn, then plastic film mulching is the key. Especially for the northern regions that need to be listed early, generally sowing seeds at the end of March and choosing early-maturing varieties, then they can be harvested and listed around June. Planting in early spring is best to preserve soil moisture by winter irrigation to prevent watering in early spring from affecting the rise of ground temperature.

4. Sowing by stages

Sweet corn is now mainly for selling tender ears or for canning factories. Therefore, it is completely different from ordinary corn, we need to predict the market situation and reasonably determine the sowing time. Sweet corn has a strong seasonality, so it needs to be put on the market in a short time. If it needs to be processed, then we also need to arrange the production and harvest plan according to the processing capacity of the processing plant to ensure the output and quality of sweet corn. If it is to sell fresh and tender corn, then the sales volume needs to be taken into account. Therefore, we have to sow seeds in stages in production, or the method of planting books in the morning, middle and evening.

The above is a brief introduction of sweet corn planting technology. That's all for today's introduction. This article is for reference only. I hope it can help you all.
