Method for constructing mango biennial area forecasting model based on meteorological conditions

Abstract

The invention discloses a method for constructing a mango biennial area forecasting model based on meteorological conditions. The construction method of the invention comprises the following steps: S1, firstly, preparing annual data of biennial mangoes; S2, further preparing meteorological data; S3, further determining a region forecasting conceptual model; and S4, finally determining a regional forecasting analysis model. The regional forecasting analysis model has the important significance that no soil nutrient annual parameters appear in the model, and it is indicated that the biennial and biennial of mangoes are mainly meteorological condition causes; and the mango biennial regulation and control technology mainly aims at meteorological conditions, that is, measures should be actively taken to prevent the flowering phase from meeting unfavorable meteorological conditions in the current season under the unfavorable meteorological year type, for example, under the condition of warm winter, flowers are picked manually or a plant growth regulator is adopted to control early blossoming, water is increased through irrigation or a rain-proof shed is built to control rainfall, and sunlight intensity is increased or reduced, and meanwhile, the occurrence of a minor year or a slightly minor year can be avoided by adjusting field microclimate.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for constructing a mango size-year regional forecast model based on meteorological conditions. Background technique [0002] my country is the second largest mango producing country in the world. Mango planting has a long history. It has developed rapidly in the past half century and has become an important characteristic agricultural industry in tropical regions. At present, there are three main mango producing areas in China, namely Hainan, Baise in Guangxi and Panzhihua in Sichuan. Hainan is the largest mango producing area in my country. Currently, off-season cultivation is mainly carried out, and the output is not obvious in different years. In Panzhihua City, the mango planting area reached 570,000 mu in 2018. Youjiang dry-hot valley in Baise City is a mango producing area in Guangxi, mainly distributed in Youjiang District, Tianyang County, Tiandong Cou...

Problems solved by technology

[0005] At present, the research results on the causes of mango small and small years are still inconclusive. There are also methods that can control the small years in production to a certain extent, but they have not yet formed a general technology or technical system. Therefore, it is urgent to design a method based on meteorological conditions. The construction method of the regional forecast model of mango size year
