The hoe manufacturer explained how to improve the utilization of light by rice

1. Improve multiple cropping index

At present, increasing multiple cropping index is an effective way to make full use of light energy and improve yield per unit area at home and abroad. After the increase of multiple cropping index, the utilization time of light energy will be extended within one year, that is, solar energy and soil power will be used in time and space.

2. Reasonable close planting

Reasonable close planting is the main measure to improve the utilization rate of light energy. If the seedlings are planted too thin, they cannot make full use of the sunlight in the field. Of course, the density of the dense lower canopy is large, and it can not be used for lighting, which is not conducive to the growth of rice. Specific to different varieties, fertilizers and seasons, the requirements should be different.

3. Improved plant

Breeding varieties with short stem, compact plant type, straight short and narrow leaves and thick leaves. In this way, not only the upper leaves can get good light and produce more nutrients, but also the lower leaves can conduct photosynthesis, and both direct light and scattered light can be used well.

4. Adjust sowing date

Two important stages in rice life cycle are meiosis of pollen mother cells and grain filling maturity. About 15 days before departure and 25 days after departure. These 40 days are the key period to determine the rice yield.

Therefore, when arranging the planting seasons of double cropping rice, medium cropping rice and single cropping rice, people should consider the local natural light conditions, try to make full use of the natural light in the late growth period.

5. Rational irrigation and fertilization

Reasonable irrigation and fertilization is an important measure to ensure the normal growth of rice plants, prevent premature senescence of leaves and prolong the photosynthetic period of leaves. At the same time, reasonable fertilizer and water conditions are also conducive to the synthesis and operation of organic matter, expanding leaf area and improving photosynthetic efficiency.
