Causes and Solutions of heading difficulties in Rice

Rice is no stranger to us, it is the staple food of 1/3 of the world's population, its yield is related to our survival, but there will be difficulties in heading when planting, seriously affecting the yield of rice. So what is the reason why it is difficult for rice to heading? How to solve it? Let's take a look at the detailed introduction.

First, the reasons for the difficulties in heading

The main results are as follows: 1. Varieties: the difficulty of heading is generally the phenomenon of neck wrapping, and the rice grains can not be pollinated in time, which is easy to form empty blighted grains, which has a great influence on the yield. This reason may be the problem of the variety, the variety itself empty grain, a great impact on the yield, the performance is more serious when it is unfavorable to the planting environment.

2. Improper application: improper application is mainly due to excessive application of triadimefon and other chemicals before heading, which can easily lead to the phenomenon of neck wrapping in rice. in addition, improper application of herbicides will also affect the growth of rice. in serious cases, there will be difficulties in heading.

3. Bad temperature: when rice heading, it is sensitive to temperature. If the temperature is too high or too low, it will also lead to the phenomenon of neck wrapping in rice, resulting in heading difficulties.

4. Lack of nutrition: long-term overcast and rainy weather will lead to serious nutrient loss of the soil, or insufficient soil fertility, resulting in the normal growth of rice due to lack of nutrition, so it is difficult to heading.

5. Diseases and insect pests: in the case of bad planting environment, especially in cloudy and rainy weather, the diseases and insect pests are more serious, light will reduce the yield, heavy will directly lose the harvest. The diseases and insect pests that affect the difficulty of rice heading are rice blast, rice borer, rice planthopper, rice borer and so on.

II. Solutions

For the rice with difficulty in heading, it is suggested that gibberellin should be sprayed first. The rice sprayed with gibberellin will heading in time within 2-3 days, resulting in poplar pollination, which can reduce the empty grain rate in time and avoid a serious decline in yield. Generally use 1-2 grams of gibberellin per mu plus 50-60 kilograms of water diluted after spray. If only local rice has heading difficulties, you only need to spray them when spraying them, do not spray to plants with normal heading, so as to avoid causing these plants to elongate too much in the later stage. In addition, low concentration of humic acid sodium salt, potassium chloride and urea solution can be sprayed at heading stage, which can enhance photosynthesis, increase seed setting rate and increase yield.
