Embodiment 1

[0042]Example 1: First collect soil nutrient data and meteorological parameters in the target area, and set monitoring sensors in the target area; determine the target crop yield and soil available nutrient content in the target area according to the output in previous years; collect the soil nutrient data collected by S1 and S2 And the meteorological parameters are input into the SWAT model for simulation calculation to calculate the nitrogen agronomic efficiency of crop planting; then calculate the amount of biological agent in the target area according to the nitrogen agronomic efficiency combined with the data monitored by the monitoring sensor; other monitoring sensors are sensitive to temperature and light Intensity detection, monitoring data combined with nitrogen agronomic efficiency to calculate scientific micro-spraying time; determine the amount and type of water-soluble fertilizer in the target area according to the amount of biological bacteria agent; pump the water...

Abstract

The invention provides a micro spraying, fertilizing and culturing method of crops. The micro spraying, fertilizing and culturing method of crops comprises the steps of collecting soil nutrient data and meteorological parameters of a target area, and arranging a monitoring sensor in the target area; determining the objective yield of crops and the content of readily available nutrients of soil inthe target area according to the yield in former years; inputting the soil nutrient data and the meteorological parameters collected in S1 and S2 in an SWAT model, performing simulated calculation, and calculating the agronomic N use efficiency of crop planting; and calculating the consumption of a nitrogenous fertilizer in the target area through combination of the agronomic N use efficiency withdata monitored by the monitoring sensor. Through spraying with micro-spraying hoses, a crop model is applied, soil and meteorological conditions are considered, fertilizing is scientific and reasonable, the objective yield is determined, the fertilizing condition is determined according to the meteorological conditions, the optimal topdressing period of a base fertilizer is determined, and through cooperation of slow release of a fertilizer by the micro-spraying hoses, nutrient release is performed according to nutrient absorption by crops.

Description

technical field [0001] The invention relates to a micro-spray fertilization cultivation method for crops, belonging to the technical field of agriculture. Background technique [0002] In the prior art, crops are various plants cultivated in agriculture. Including food crops and economic crops (oil crops, vegetable crops, flowers, grass, trees) two categories. "Food is paramount to man", which expresses the relationship between man and food, and a reasonable diet can bring health to human beings. The growth of crops is inseparable from scientific and technological production technology. [0003] Traditional crop fertilization In order to obtain high yields and benefits, farmers use a large amount of chemical fertilizers. Blindly excessive and unbalanced fertilization has almost become a common phenomenon, especially in some economically developed areas, and blind fertilization has not increased the yield. , production levels stagnated. [0004] Therefore, how to use mode...
