u is the difference between the soil tension value of the first land after irrigation is finished and the soil tension value after irrigation is started, and is specifically expressed by the following formula:
U＝Ub-Ua
wherein, UbSoil tension value, U, for ending irrigation of the first landaStarting the soil tension value of irrigation for the first land;
(4) and after the irrigation of the last land is finished, returning to the first land, monitoring the soil tension value of the first land by the sensing equipment, and judging whether a new round of irrigation is started or not.
2. A method for alternate irrigation of plants according to environmental parameters as claimed in claim 1 further comprising the steps of: at any moment, if the sensing equipment detects rainfall, stopping irrigation of the current irrigation land; after rainfall, the rainfall amount condition of the first land is detected according to the sensing equipment, and rainfall compensation irrigation time T is calculatedbConcrete rainfall compensation irrigation time TbThe expression is as follows:
Figure FDA0002523833550000024
wherein R is rainfall R mm, SnThe irrigation area of the current irrigated land is shown, and Q is the flow Q cubic meter/second of an irrigation water pump;
if Tb＜TnContinuing irrigation of the currently irrigated land and alternately irrigating according to the original sequence, wherein the standard irrigation time of the currently irrigated land and the rest land is T'n，T'nThe specific expression is as follows:
T′n＝Tn-Tb
wherein, TnFor the current standard irrigation time for irrigating the land, TbCompensating for the irrigation time for rainfall;
if Tb＞TnAnd starting to judge whether to start irrigation from the first land.
3. A method for alternate irrigation of plants according to environmental parameters as claimed in claim 1 further comprising the steps of:
(5) after the soil returning to the first land provided with the induction equipment is irrigated in turn, the soil tension value of the irrigation is opened again, and the soil tension value U of the irrigation is directly opened according to the preset valuea。
4. A system for alternate irrigation of plants according to environmental parameters according to any of claims 1 to 3, characterized in that: the system comprises an irrigation water pump, a valve, a processing chip, sensing equipment and a memory; the perception device comprises: a rainfall sensor, an air temperature sensor, an air humidity sensor and a soil tensiometer.
