Causes of cracking of sugarcane

Sugarcane is one of our favorite fruits, we often buy cracked sugarcane when we buy, this kind of sugarcane has serious water loss and tastes bad. And this phenomenon is also a headache for growers, so what is the cause of sugarcane cracking? Let's take a look at the detailed introduction.

1. Lack of water

From the sprouting stage to the harvest period, sugarcane has a great demand for water, and it is also sensitive to water. according to the research of relevant departments, for every 1 ton of sugarcane, it needs to consume about 130 tons of water. And its water demand law is less at both ends and more in the middle, that is, water demand for watering at the seedling stage and mature stage, while the water demand at the extension stage is the most. Generally speaking, the water requirement is about 40% at the seedling and mature stage, and about 60% at the elongation stage, and once the sugarcane is short of water during the elongation period, it will lead to sugarcane cracking.

2. Reasons for variety

Different varieties of sugarcane have different degrees of cracking. Generally speaking, the skin of sugarcane is hard and the varieties with strong cork layer should not crack; on the contrary, the varieties with thin skin and weak tissue of cork layer are easy to crack. Therefore, when planting, we should choose varieties with thick and hard skin and not easy to crack.

3. Calcium deficiency

In the process of drying and growth, a variety of elements are needed, in addition to conventional nitrogen, phosphorus and potassium, there are also many trace elements, in which calcium is related to the tissue structure of sugarcane skin. However, when it is dry and deficient in calcium, its sugarcane skin tissue cells will grow slowly and can not keep up with the expansion of internal tissue, so cracking occurs. Therefore, it is necessary to increase the application of organic fertilizer to provide a variety of elements for the plant, and the foliar fertilizer can be applied in the middle and later stages of growth to maintain calcium and make it grow normally.

4. Low temperature frost

In the mature period of sugarcane is the low temperature season, if the ground frost climate, the moisture of sugarcane will freeze, directly break the skin of sugarcane, appear cracking phenomenon, which is also the main reason for the cracking of normal sugarcane. For this situation, to do a good job of cold resistance and freezing maturity, binding, smoking, watering and other measures can be used to improve the cold resistance and freeze resistance of sugarcane and reduce cracking.

The above is the introduction of the causes of sugarcane cracking, hope to help you, want to know more related knowledge, please pay attention to us.
