Detailed Explanation of Key Points of Rice Cultivation Techniques: Master Scientific Planting Methods

As a super rice power, China has always been an important force in promoting rice development in the world. So how much do you know about the key points of rice cultivation techniques? Let's take a look together!

1. Key Points of Rice Cultivation Techniques

To cultivate rice, you need to master seven steps: land preparation, seedling raising, weeding and pest control, fertilization, irrigation and drainage, drying, and screening. Nowadays, machines are mostly used instead of manpower; for seedling raising, you can choose rice seedlings from a seedling center. Groups engaged in large-scale planting will choose a rice transplanter for transplanting, while rice fields of irregular shapes are transplanted by hand. Weeding, fertilization, and irrigation and drainage are carried out according to the daily growth changes of the rice seedlings, and on the harvest day, drying and finally screening are required.

2. Precautions for Ventilation of Rice Seedbeds

1. When ventilating to harden seedlings, note that the lower part of the greenhouse opening should be blocked with woven fabric, plastic film, etc., to avoid strong wind blowing directly on the seedlings.

2. Small seedlings should be ventilated on the leeward side, while large seedlings can be ventilated more fully.

3. Ventilate according to the temperature difference between day and night: when the temperature difference is too large, the ventilation time should be shorter; when the temperature difference is small, the ventilation time can be increased.

4. Prevent low-temperature cold damage. If the minimum outside temperature is below 0°C, warming measures must be taken, such as adding a charcoal brazier, gas tank, heat lamp, smoke bomb, etc.

5. If the minimum outside temperature is below 10°C, close the greenhouse early around 3 p.m. to keep it warm.

6. If low-temperature freezing damage occurs, ventilate early in the morning to alleviate leaf wilting caused by freezing.

7. Seedling fields that have entered the 3-leaf stage should be ventilated more intensively to harden the seedlings. Especially on cloudy days, the greenhouse head should also be opened in the morning for ventilation to dissipate moisture inside the greenhouse, so that the seedling field remains in a dry-raised state and strong seedlings are cultivated.

Overall, everyone should pay attention to rice cultivation issues, and the most suitable approach is to adapt measures to local conditions.
