Embodiment 1
[0058] Dongying Guangbei Farm No. 2 Forage Test Base, with a test area of 1335m2 2 The basic soil fertility of the test site is shown in Table 3, and the cutting test was started in mid-July, 2008.
[0059] Table 3 Soil fertility of each test base
[0060]
[0061]
[0062] Specific steps are as follows:
[0063] a. Seedbed preparation
[0064] On the land where Apocynum is going to be planted, select 10×10m 2 The land is used as a seedbed, mixed with crushed wheat straw and farmyard manure, plowed 20cm deep, raked and raked finely, and the surrounding area is used as a furrow, according to 4500m 3 / hm 2 The amount of irrigation is flooded with water to suppress the alkali. 150kg of farmyard manure and 100kg of crushed wheat straw were mixed with the soil and applied. Ridge by 1m ridge distance, ridge height 15cm, dig three rows of ditches in the ditch, ditch depth 15cm, width 20cm, the soil from the ditch is temporarily placed on the edge of the ditch, in order ...
