2. the planting layer adopted by the application can be planted by adopting an original soil structure, and can be the soil specially designed by the application; for the water storage layer, mainly when the rainfall is more, the water in the planting layer needs to be led out; when no water exists, the planting layer in the furrow can be led in, so that a certain local water storage effect is achieved;
3. according to the method, a certain fertilizer is arranged in the early stage, and then the required fertilizer, namely nitrogen and phosphorus, is supplemented in the later stage through additional fertilization; because the rhizobia is not enough to develop after the alfalfa enters the bud stage and the nitrogen fixation capacity is weak, the requirement of the alfalfa can be met by increasing the nitrogen fertilizer at the moment;
4. this application is through setting up permeable bed and the reservoir bed that contains the gravel for there is certain self matching nature between the two, thereby can improve when needs carry out the exchange of water between permeable bed and reservoir bed, can have better combining effect.
Detailed Description
In order to clearly illustrate the technical features of the present solution, the present application will be explained in detail through the following embodiments.
In a first embodiment, a method for ridging live alfalfa includes the steps of:
s1, preparing seedbeds, wherein the length of all the seedbeds is the same, and the seedbeds are not shielded by tree shades and the like:
the seeding bed comprises a plurality of rows of ridge beds arranged at intervals, and furrows are respectively arranged on two sides of each ridge bed;
the compositions of the water storage layer and the planting layer are shown in table 1;
table 1:
s2, sowing: the number of rows, the distance between each row, the seeding amount and the like arranged on each ridge bed are shown in table 2;
table 2:
| serial number | Line number | Seeding rate | Line spacing (cm) |
| 1 | 4 | 1 kg/mu, naked seed | 15 |
| 2 | 6 | 1.5 kg/mu, coating seeds | 20 |
| 3 | 8 | 1.8 kg/mu, coating seeds | 25 |
