How to grow sugarcane is sweet

Sugarcane is rich in sugar and water, as well as vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism, which are mainly used in sugar production. So, how can sugarcane be sweet?

I. selection of sites

The greenhouse for planting sugarcane needs to choose a deep, loose and fertile land to fully meet the needs of its root growth, so that the root system can better play the role of absorbing water and nutrients.

II. Soil preparation and fertilization

Deep ploughing is the basis for increasing production. The root system of sugarcane is well developed, and deep ploughing is beneficial to the development of root system, which makes the aboveground part grow fast and the yield is high. Deep ploughing is a general principle and requirement. The specific degree of deep ploughing must be adjusted to local conditions, depending on the depth of the original ploughing layer and soil properties, generally about 30 cm. Fertilizer is mainly organic fertilizer, phosphorus, potassium fertilizer and a small amount of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer are mainly used as base fertilizer, because the absorption of phosphorus fertilizer by sugarcane is mainly in the early and middle stages. Then plant seedlings in a sugarcane furrow with a row spacing of 90-100 cm.

III. Field management

1. Uncover film to replenish seedlings

The sugarcane field covered with plastic film should uncover the film and check the seedlings as soon as possible. for newly planted sugarcane, when the lack of seedlings reaches 30 cm, the seedlings should be replenished in time in cloudy and rainy days, and the best leaf age is 2-3 leaves.

two。 Fertilize and cultivate the soil

Sugarcane tillering is the period of a large number of long roots, long leaves and tillering, which requires more nutrients. Early fertilization can promote the growth of tillering seedlings, catch up with the main seedlings and increase the number of effective stems. Before the middle of May, tillering fertilizer was applied in combination with small cultivation soil after rain, 100 kg / mu of special compound fertilizer for sugarcane (or 25 kg of urea + 20-25 kg of potassium chloride) and 8-10 cm of soil to protect and promote tillering. the thickness of seedlings can be increased appropriately if the number of seedlings is sufficient. In the middle and last ten days of June, combined with Dapei soil to apply stem fertilizer, 25-30 kg urea per mu, soil thickness 20-30 cm, tiller control. Micro-fertilizer can also be sprayed on the weak sugarcane fields.

3. Inter-seedling fixed seedling

After tillering, sugarcane will have too many seedlings, which not only consumes nutrients, but also leads to the growth of thin and weak sugarcane seedlings, which is difficult to grow into stems and is prone to diseases and insect pests. Therefore, for the seedlings with too many seedlings and time seedlings, the standard seedlings should be 15% more than the target effective stems, that is, 8-10 sugarcane seedlings per meter. The time of setting tillers generally leaves male tillers with low nodes in tiller seedlings and sturdy tiller seedlings when weak tillers are removed.

4. Control of diseases and insect pests

The main pests are sugarcane borer, sugarcane tortoise, thrips and woolly aphids. Diseases include smut, tip rot and so on.

If you want to plant sweet sugarcane, land preparation, fertilization, field management and other aspects are very important.
