Problems solved by technology

[0005] The purpose of the present invention is to provide a method suitable for machine-transplanting rice in view of the existing fertilization methods that require multiple fertilization during the entire growth period, the supply of fertilizer nutrients does not meet the law of rice growth requirements, and cannot meet the nutritional needs of rice during the entire growth period. One time fertilization method throughout the growth period

Embodiment

[0030] The used quick-acting fertilizer component of present embodiment surface layer mixed application is compound fertilizer, and the mass percent of nitrogen, phosphorus, potassium (in terms of nitrogen, phosphorus pentoxide, potassium oxide) is 15%: 15%: 15%, commercially available product. The proportion of the components of the controlled-release compound fertilizer used for deep application is as follows:

[0031] Single season indica rice:

[0032] The nitrogen ratio of quick-acting nitrogen fertilizer, 45-day controlled-release fertilizer (15-15-15), and 75-day controlled-release fertilizer (20-0-20) is 20%:50%:30%.

[0033] Single crop japonica rice:

[0034] The nitrogen ratio of quick-acting nitrogen fertilizer, 50-day controlled-release fertilizer (15-15-15), and 90-day controlled-release fertilizer (20-0-20) is 20%:30%:50%.

[0035] The values ​​in the parentheses of the above components are the commonly used labels for the nutrient content of core fertilizers ...

Abstract

The invention relates to the technical field of agricultural production, in particular to a rice machine planting one-time fertilizing method. A furrow opener is adopted to dig a furrow with the depth of 15 cm to apply a controlled release compound fertilizer in the portion, at the front end of a rice transplanter, in the middle of a seedling row, a fast-release fertilizer is applied in the portion, at the tail of the rice transplanter, in the middle of the seedling row, and the field face is smeared to be flat. The purposes of increasing the rice yield and improving the utilization efficiency of the nitrogen fertilizer can be achieved, compared with a common machine planting multi-time fertilizing method, the rice machine planting one-time fertilizing method has the advantages that the yield can be increased by 9.96%-12.75%, and the utilization efficiency of the nitrogen fertilizer can be improved by 53.86%-54.20%.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a one-time fertilization method for rice machine insertion. Background technique [0002] Rice is one of the most important food crops in my country. Facing the current situation of population growth, decrease of arable land, and rapid growth of food consumption demand, it is imperative to increase rice production. Nitrogen fertilization is one of the important means to increase rice production. In the past 50 years, the world's grain production has risen sharply, partly because of the increase in the input of fertilizers, especially nitrogen fertilizers. At present, the average amount of nitrogen fertilizer used in a single season in rice fields in my country is 180kg / hm 2 , 75% higher than the world's unit area consumption. The existing methods of fertilization are mainly artificial surface application, and there are other methods such as mechanical ditching a...
