Embodiment 1
[0045] The water-saving cultivation method of drip irrigation under the film of corn is as follows:
[0046] 1) First design the drip irrigation system and arrange the drip irrigation pipes. The specific steps are as follows:
[0047]Determination of the control area: the water volume balance calculation should be carried out at the time of design to determine a reasonable control area. When the water source is a motorized well, the largest possible control area should be determined according to the outflow of the motorized well. When the water sources are rivers, ponds, or canals, the optimal control area should be determined by considering both the water volume and economic factors of the water source. According to previous design experience, the more economical control area is 66.7 hectares (1000 mu), and it is best not to exceed 100 hectares (1500 mu), and most of them are irrigated with single crops.
[0048] Pipeline network planning and layout steps: a. Determine the ...
Embodiment 2
[0097] 1) Same as step 1) in Embodiment 1 of the present invention;
[0098] 2) Same as step 2) in Embodiment 1 of the present invention;
[0099] 3) Apply basal fertilizer first, that is, apply 1800kg of organic fertilizer per mu, 30kg of slow-control fertilizer, 23kg of diammonium phosphorus, 37kg of potassium sulfate, and 1-1.5kg of zinc sulfate, and then use drip irrigation under the mulch for 8 times, respectively for the jointing period Watering 1 time, watering 1 time during the period of small trumpet mouth, watering 1 time during the period of large bell mouth, watering 1 time during the tassering period, watering 1 time after the tassering period, watering 1 time during the grouting period, watering 2 times during the ripening period; and topdressing 3 times The second time is the jointing fertilizer at the jointing stage, the panicle fertilizer at the big bell mouth period, and the grain fertilizer at the end of tasseling period. Water is passed through the fertiliz...
experiment example 1
[0128] After the relationship between the amount of irrigation water and the output in the embodiment of the present invention and comparative example 1 is tested, draw the following data, specifically see the following table 1:
[0129] Table 1 The relationship between yield and irrigation water
[0130]
[0131] As can be seen from Table 1, wherein the 4th vertical line corresponds to the best embodiment 2 of the present invention, the last vertical line corresponds to comparative example 1, and the first three vertical lines are designed in order to understand the relationship between output and irrigation water volume Parallel experiment, concrete implementation method is identical with embodiment 2, just irrigation water quantity is different, so also can clearly find out from above table, adopt water-saving cultivation method of the present invention to improve yield, but irrigation water quantity is too much or too little other The output will also be reduced accordi...
