Due to the varied weather conditions, this year's early rice seedlings grew slowly, with fewer occurrences of childbirth, and the growth was not as good as normal years. At present, early rice has entered a period of young panicle differentiation. As long as it is strengthened, it is still expected to achieve a good harvest. Hereby, it is recommended that farmers take corresponding measures based on early rice seedlings, do a good job in the management of early rice in the middle and late fields, and promote the early rice harvest.
Fertilizer application Early rice has reached the initial stage of young panicle differentiation, and production should be based on seedling potential, application of good nitrogen fertilizer and potash fertilizer to achieve the purpose of increasing the number of effective panicles and grains per panicle. Generally, 3-5 kg ​​of urea and 3-5 kg ​​of potassium fertilizer are applied per acre. In addition, if the color of the leaves at the heading stage is light green, the seedlings should also be treated with granule fertilizer, generally 1-2 kg of urea per acre, or foliar fertilizer, and the specific amount should be determined according to the condition of the seedlings.
Do a good job of water pipes to achieve long-term water spikes and late wet and strong seeds. For late-onset fields that have not yet been cultivated in the sun, attention should be paid to water control and seedlings; for paddy fields that have been cultivated in the field, dry and wet intermittent irrigation is used after rehydration, which is conducive to the control of rice root growth and pests and diseases, and shallow water irrigation is used during heading. To the heading of water, in order to facilitate the ordering and maturity of the same.
This year, it is expected that pests and diseases of early-season rice will be moderately heavy year. According to the pest information of the local plant protection department, appropriate pesticides should be selected and applied in sufficient amounts at the right time. A key prevention and control is generally implemented during the early rice break period to effectively control sheath blight and rice blast. Diseases and other diseases ensure that there are no major pests and diseases in the middle and late fields of early rice. Where conditions permit, centralized prevention and control should be carried out in order to increase control effectiveness and reduce pesticide use.
Harvesting early or late rice harvest at a timely manner will affect the formation of early rice yield and quality. Early harvest is often accompanied by continuous bad weather such as high temperature and heavy rain, and it is prone to sprouting, resulting in reduced yield and quality. About 25 days after the panicle start, 90% of the husks are generally yellowed. It is necessary to take the machine to take off the machine, improve the harvesting efficiency, and promote the early rice grain return.
