Blank group
No coating treatment was performed.
Experimental methods
And (3) determination of germination percentage: the seeds were incubated in a 20 ℃ incubator for 10 days. The germination percentage calculation formula is as follows: the germination rate is the germination number/the number of seeds to be tested multiplied by 100 percent.
Determination of emergence rate, plant height and biomass:
setting 75-80% of the maximum water holding capacity of the soil as non-drought (namely drought gradient 1); setting the maximum water holding capacity of 55-60% as mild drought (namely drought gradient 2); setting the maximum water holding capacity of 35-40% as medium drought (i.e. drought gradient 3); setting the maximum water holding capacity of 15-20% as severe drought (namely drought gradient 4). The test has 5 seed treatment groups of an experimental group, a control group 1, a control group 2, a control group 3 and a blank group, and each seed treatment group is subjected to four times of repeated tests under 4 drought gradients. And planting the seeds of each treatment group in flowerpots under different drought gradients, and strictly controlling the water content of the soil in the planting process. Counting the rate of emergence after sowing and seedling emergence, measuring the plant height in the growth process, and measuring the biomass in the harvest process, wherein the specific measurement indexes and the method are as follows:
biomass determination:
after the test is finished, pouring the alfalfa out of the flowerpot, washing the roots in water, quickly absorbing the water on the plants by using water absorption paper, and weighing the fresh weight of the parts of the ground, the underground, the stems and the leaves by using a balance respectively. Then, each part is respectively put into paper bags, the water is removed for half an hour at 100 ℃ in an electric heating constant temperature blast drying oven, then the paper bags are dried to constant weight at 60 ℃, and the dry weights of the parts of the ground, the underground, the stems and the leaves are respectively weighed by a balance.
The emergence rate calculation formula is as follows: the rate of emergence is the number of seedlings/the number of sown seeds multiplied by 100%
Plant height measurement:
the first plant height measurement was made 1 month after emergence using a steel tape, and every week thereafter to an accuracy of 0.01 cm.
The experimental results are as follows:
The germination rates are shown in the following table:
| Treatment of | The germination percentage is% |
| Experimental group | 82 |
| Control group 1 | 60.1 |
| Control group 2 | 65.3 |
| control group 3 | 72.5 |
| Blank group | 53 |
Under the drought gradient 1, the emergence rates of the experimental group, the control group 1, the control group 2, the control group 3 and the blank group are 82 percent respectively; 67%; 65 percent; 71 percent; 60 percent; under the drought gradient 2, the emergence rates of the experimental group, the control group 1, the control group 2, the control group 3 and the blank group are 82 percent respectively; 67%; 65 percent; 71 percent; 60 percent; under drought gradient 3, the emergence rates of the experimental group, the control group 1, the control group 2, the control group 3 and the blank group are 82% respectively; 62 percent; 63%; 70 percent; 56 percent; under the drought gradient 4, the emergence rates of the experimental group, the control group 1, the control group 2, the control group 3 and the blank group are 82 percent respectively; 59 percent of water; 61%; 67%; 52 percent.
The results show that under the same drought gradient, the plant height increases faster in the first 3 times of measurement, and the plant height increases slower from the 3 rd week. With the increase of drought, the plant height growth amount is reduced. The plant height, the emergence rate of the alfalfa and the biomass of the alfalfa in the experimental group are higher than those of other treatment groups, and the agricultural chitin, the potassium sulfate and the polyglutamic acid have a synergistic function, so that the drought resistance of the alfalfa can be improved, and the yield of the alfalfa can be improved.
