Embodiment 1

[0031] Step 1. Take 10 consecutive days in a season as a test cycle, water the target plot on the first day, and use the watering amount on the first day as the standard watering amount, and use the watering amount on the first day as the standard watering amount. Point measurement of the soil moisture value of the target plot; wherein, the target plot is a test plot in the plastic greenhouse, and the plastic greenhouse includes the test plot and a plurality of common plots, during the test period The temperature and light conditions in the internal control plastic greenhouse remain unchanged;

[0032] Step 2. Use the soil moisture value in the test period to draw the soil moisture curve, so as to obtain the change law of soil moisture, and find the time node when the soil moisture drops to 50% of the soil moisture value of the first day and the first day. Days interval, the current calculated days interval is 6 days;

[0033] Step 3. In this season, water the target plot onc...

Abstract

The invention discloses a water-saving greenhouse irrigation method. The water-saving greenhouse irrigation method comprises the following steps: step 1, with 10 to 15 consecutive days in a quarter of a year as a test period, watering a target land block in the first day, wherein the watering amount in the first day is used as a standard watering amount, and measuring the soil humidity value of the target land block at 9 to 10 o'clock every morning, wherein the target land block is a test land block in a plastic greenhouse, and the plastic greenhouse comprises the test land block and a plurality of ordinary land blocks; step 2, drawing a soil humidity curve by utilizing soil humidity values in the test period, and finding out the interval of the number of days between the first day and the time node of the soil humidity value decreased to 50% of the soil humidity value measured in the first day; and step 3, in the same quarter of the year, watering the target land block once every interval of the number of the days, and watering the plurality of the ordinary land blocks at the same time, wherein the watering amount every time is consistent with the standard watering amount. The water-saving greenhouse irrigation method provided by the invention meets the water demand of the land, and improves the utilization efficiency of water resources.

Description

technical field [0001] The invention relates to a water-saving greenhouse irrigation method. Background technique [0002] With the development of the economy, agricultural water is becoming increasingly scarce. At present, when irrigating the land, a very low-level primitive method is still used, that is, relying on experience to judge whether the land is short of water, and then irrigating based on experience. This will inevitably cause waste of water resources, affect the efficiency of water resources utilization, and increase the cost of agricultural planting. Contents of the invention [0003] Aiming at the above technical problems, the present invention designs and develops a water-saving greenhouse irrigation method that can improve water resource utilization efficiency. [0004] The technical scheme provided by the invention is: [0005] A water-saving greenhouse irrigation method, comprising the following steps: [0006] Step 1. Take 10 to 15 consecutive days ...
