Field Management of Rice During Jointing and Heading Stage

Rice is grown in many areas. If you want to achieve high rice yields, you need to do corresponding management work. In the rice growth cycle, the jointing and heading stage is considered to be a crucial period. It is directly related to the yield and quality of rice. Let's talk about the field management of rice during the jointing and heading stage.

1. Scientific topdressing

During the jointing and heading stage, rice's demand for nutrients increases sharply, especially for key nutrients such as nitrogen, phosphorus and potassium. Therefore, scientific topdressing is crucial. Top dressing needs to be determined based on actual field conditions, including soil fertility, rice variety and growth conditions. The purpose of topdressing is to meet the nutrient needs of rice during the jointing and heading stage, and to promote the formation of ears and the growth of rice.

2. Moisture management

Water management is another key aspect of field management during the jointing and booting stage. In hot weather, the water demand of rice increases significantly, so it is necessary to ensure that the soil remains moist to meet the growth needs of rice. Insufficient water will lead to reduced rice yield and poor growth, so timely irrigation is necessary. In addition, excessive irrigation should be avoided to prevent oxygen deprivation in the rice roots and the breeding of pests and diseases.

3. Prevent lodging

Rice grows rapidly during the jointing and heading stage, and the plant height increases, making it prone to lodging. Lodging will reduce rice yield and increase the difficulty of harvesting and management. In order to enhance the lodging resistance of rice, silicon fertilizer can be applied. Silicon fertilizer can increase the mechanical strength of rice plants, reduce the risk of lodging, and thus increase yield.

4. Weeding

Weeding is an important task in field management during the jointing and booting period. The growth of herbaceous weeds will occupy the nutrients and light resources of rice, causing serious impact on the growth of rice. Especially during the jointing and heading stage, the growth rate of rice is accelerated and it is vulnerable to competition from weeds. Therefore, timely weeding is necessary. For plots with more weeds, manual or mechanical weeding methods can be used to avoid the use of chemical herbicides to reduce the impact on the environment.

5. Field management

When carrying out field management during the jointing and heading period, some details need to be paid attention to. First of all, we must closely observe the growth of rice and promptly detect and deal with pest and disease problems. Secondly, avoid applying fertilizer in hot weather to avoid damaging the growth of rice. Additionally, check your irrigation system regularly to ensure it is receiving adequate water . Finally, field management strategies should be adjusted according to local meteorological conditions and temperature changes to adapt to different climatic conditions.
