Management techniques of heading and fruiting stage of Black Rice

Black rice is a special variety of rice, its nutritional value is higher than ordinary rice, but also has a very high medicinal value, we often use it to cook porridge or make other nutritious food in life. In the process of black rice planting, the heading and fruiting stage is the key period to determine the black rice planting yield, and the management of this period is very important, so how to manage the black rice panicle fruiting stage? Let's get to know it with the editor.

1. Reasonable water management

In the heading stage of black rice, it is a period when it is sensitive to water, so it should be kept in shallow water from heading to filling stage. if there are plots with greedy green growth or high groundwater level, intermittent irrigation can be carried out, and sand fields should be irrigated in water layer. In the wax ripening stage of black rice, the irrigation times of dry and wet, mainly dry and wet, and horse running water at the end of wax ripening should be adopted, which is beneficial to enhance soil permeability, improve root activity and enrich grains. In order to promote yellow ripeness and facilitate harvest, generally drain the water one week before harvest, and remember to cut off the water to dry, so as not to reduce the single grain weight.

2. Fertilization as appropriate

In the process of grain filling, nitrogen transported from leaves to rice grains and Tangfeng were always input in a certain proportion. If nitrogen is insufficient, then nitrogen elements in stems and leaves will be transferred to grains, resulting in premature senescence of leaves and reduction of photosynthates. Therefore, in the filling period, we should apply a small amount of nitrogen fertilizer to prolong leaf life, effectively enhance photosynthesis, promote grain fullness and increase grain weight, which is an important measure to improve yield and quality.

3. Lodging prevention

In addition to paying attention to base fertilizer, reasonable close planting and strengthening field management, we should also pay attention to prevent early water cut-off and deep water irrigation in the later stage, so as to avoid lodging caused by withering and soft stalks.

4. prevention and control of diseases and insect pests

The main disease and insect pest in the heading and fruiting stage of black rice is panicle and neck rice blast, which is the main disease in the process of rice planting. The second is bacterial blight and sheath blight, we should do a good job in targeted prevention and control, and pay attention to safety when spraying, avoid direct contact with the skin, and do not damage the leaves.

The above is the introduction of the management technology of the heading and fruiting stage of black rice. I hope it can help you. If you want to know more about it, please follow us.
