The corn girl is long, time-consuming and time-consuming, but it won't increase production.

Corn girl broke long, long break, time-consuming and laborious, will not increase production!

Commonly known as corn Yazi, that is, the tillering of corn, in fact, tillering is a feature of Gramineae plants, such as wheat and rice have a strong tillering ability, but in the process of evolution, the tillering ability of corn is gradually weakened. at present, the number of tillers in corn is relatively small.

However, you may have noticed that although there are fewer tillers in corn, the tillers of many plants will grow again and again after breaking apart, repeatedly breaking up, and so on, that is to say, although the characteristics of tillering have weakened in the process of evolution, they have not disappeared.

So is it necessary to remove tillers? Scientific development of agriculture with data to tell you: it is completely unnecessary, it can be said to be time-consuming and laborious, futile work!

According to the data of production practice, only about 3% of the tillers in the field can grow into plants, while the rest gradually die after the maize enters reproductive growth. Naturally, that is to say, about 97% of the tillers are wasting the nutrition of the plant? Obviously not. In fact, there are many advantages to retaining tillers. Let's talk about it next.

Increased the photosynthetic capacity of the plant.

Due to the existence of tillers, the leaf area of maize plants has been expanded, compared with non-tillering plants, the leaf area increased by 30-80%, naturally can also produce more dry matter accumulation for corn.

Help to store water and preserve fertilizer

Maize seedling stage is usually the most dry time, drought is also the most sensitive to the impact of plants, but tillering not only increases the area, but also reduces the direct transpiration of the soil surface, which is conducive to water storage. The results showed that the soil water content of 10 cm depth of tillering plants was 14% higher than that of non-tillering plants.

Increase root system

The average number of maize roots of plants with tillers was 56, while that of plants without tillers was 29. It was clear that corn plants with tillers were stronger, especially in extreme storm weather.

Many farmers think that tillers cannot bear fruit and consume a lot of nutrients, but those who understand the law of plant growth should know that the peak of plant nutrition consumption is in the reproductive growth stage. however, most tillers die gradually when they enter reproductive growth, that is to say, these tillers continue to contribute in the early stage, but do not consume additional plant nutrients in the reproductive growth stage.

On the other hand, the related research also shows that the nutrition synthesized by tillers will be transferred to the main stem, and after entering the reproductive growth stage, the nutrition of non-panicle tillers is like the ear of the main stem, which is also a major reason for maize to retain tillers and increase production.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
