1. Rice growth habits

Rice is a plant of Poaceae and Oryza genus. It is also the most important grain crop in China. It is mainly planted in paddy fields. There are many varieties of rice. According to the maturity time, it can be divided into early, medium and late maturity types.

The harvest season and harvest frequency of rice in different regions are also different. Some regions can only grow one season of rice a year, and some regions can grow two or three seasons of rice.

II. What about rice seedling injury?

1. Irrigation and drainage remediation can be carried out. Repeated water change in the field can reduce the concentration of phytotoxicity, and then apply a small amount of organic fertilizer to help rice seedlings continue to grow.

2. If the phytotoxicity is not too serious, a small amount of fertilizer can also be applied to restore the growth of rice seedlings;

3, can also spray gibberellin, natural brassin for remediation.

III. How to use foliar fertilizer for rice?

Rice foliar fertilizer is a fertilizer that can comprehensively supplement the nutrients needed by rice in the vegetative stage and booting and fruiting stage. It is easy to cause phytotoxicity if it is not used properly. The correct use method is as follows:

1. Generally, spraying is most suitable at early rice big embryo, initial ear, filling and full ear stage, and it takes more than one hour to spray once per mu;

2. When using solid foliar fertilizer, it needs to be processed into liquid fertilizer before use;

3. Fertilize according to the growth of rice seedlings, so as to effectively increase production;

4. The spraying time should be selected from the booting stage to the breaking stage of rice, and the spraying time should be selected before 9:00 a.m. or after 4:00 p.m. when there is no wind or cloudy day, or when the humidity is high and the evaporation is small.
