Embodiment 1

[0024] The cultivation and management method of the field ryegrass multiflora that improves soil urease activity described in embodiment 1 includes the interactive influence of two kinds of agricultural management measures (sowing amount*fertilization amount); before sowing, the ryegrass multiflora seeds are soaked for 8~12h , when sowing, mix the multiflora ryegrass seeds and fine sand at a mass ratio of 1:8, and spread them on the bottom of the rice; the sowing time is from September to October.

[0025] 1.2kg·mu -1 Seeding rate*52kg·mu -1 Fertilization rate (S1.2 F14): seeding rate 1.2kg per mu -1 , the application rate of base fertilizer 3 days before sowing is 10kg·mu -1 , 60 days after sowing for the first mowing, and within 3 days after the first mowing, 14kg·mu of mowing fertilizer should be applied -1 105 days after sowing, cut for the second time, and apply cutting fertilizer 14kg per mu within 3 days after the second cut -1 135 days after sowing for the third cu...

Embodiment 2

[0027] The cultivation management method of the field ryegrass multiflora that improves soil urease activity described in embodiment 2, comprises the interactive effect of two kinds of agricultural management measures (sowing amount*fertilization amount); Soak ryegrass multiflora seeds for 8~12h before sowing , when sowing, mix the multiflora ryegrass seeds and fine sand at a mass ratio of 1:8, and spread them on the bottom of the rice; the sowing time is from September to October.

Abstract

The invention relates to a cultivation management method for field loliummultiflorum capable of improving the urease activity of soil. According to the cultivation management method, a proportional relation between the seeding rate of the loliummultiflorum and the fertilizer application rate is that the seeding rate of the loliummultiflorum is 1.2-2.0kg.mu<-1>, the fertilizer application rate is 52-64kg.mu<-1>, and the fertilizer application time is 4-5. The method can effectively improve the urease activity of the soil; the relatively high urease activity in the soil can promote available nitrogen of plants increased, and hence, the method also has a certain function of increasing total nitrogen of the soil; and the method has a positive effect on improvements of a cultivation managementtechnique for the loliummultiflorum.

Description

technical field [0001] The invention belongs to the field of pasture planting, and in particular relates to a method for cultivating and managing ryegrass multiflora in the field for increasing the activity of soil urease, and the method can increase the yield of pasture at the same time. Background technique [0002] Lolium multiflorum (Lolium multiflorum) is an annual or perennial temperate grass forage with the characteristics of high yield, fast growth and excellent grass quality. Its culm is erect, with 4-5 nodes, thinner to thicker. Leaf sheaths loose; ligule up to 4 mm; blade flat, glabrous, slightly scabrous above. Spike-shaped raceme erect or curved; rachis soft, glabrous at internodes, slightly rough above; spikelets containing florets; internodes of rachises smooth and glabrous; glumes lanceolate, hard in texture; lemma oblong-draped Needle-shaped, with 5 veins, apex membranous transparent, with thin awns about 5(-15) mm long, or upper florets without awns; ridg...
