Following content is the Performance comparision using the rice nutrition liquid used in the rice nutrition liquid of the example 2 of the present embodiment and prior art:
Test and carry out in the contracted field in richly endowed village, pioneer town, Wangkui County, experimental cultivar is no loadtransformer; 2 process are established in test altogether: be the rice nutrition liquid formula of this example 2 and formula of the prior art respectively.Each process 60 is coiled, on the seedling plate that random arrangement is smooth at same, fertility is consistent.Two kinds of nutritive mediums are all adopt perlite as the soilless breeding seeding technology of seedling raising ground substance.April 20 was sowed, and the amount of broadcasting is 500-600g/ ㎡, and examination on May 15 rice shoot, May 16 transplanted.3 repetitions are established in land for growing field crops, Ji12Ge community, each community 1334 ㎡, random alignment, and between process, the field seedling number that falls is all identical with other Fretilizer systems of land for growing field crops.
Table 3 is process mature seedling and seedling quality situation respectively
As seen from Table 3, the nutritive medium of example 2 of the present invention is compared with nutritive medium of the prior art, seedling rate and adult seedling rate exceed 8 and 7.6 percentage points respectively, wide increase by the 0.8-1.2mm of stem foot, hundred strain dry weights increase by 0.9-1.44g, and other index is also obviously better than the formula of the rice nutrition liquid of prior art.This rice nutrition liquid showing that example 2 of the present invention provides can significantly improve the quality of seedlings (comprising Ye Se and Ye Miao quality).
Table 4 is process economic characters and yield comparison respectively
Process The formula of example 2 Prior art formula
Fall Tian Miao (ten thousand/mu) 8.7 8.0
Most Gao Miao (ten thousand/mu) 35.32 30.14
Effective fringe (ten thousand/mu) 31.87 27.12
The percentage of earbearing tiller (%) 90.8 85.8
Every total grain panicle number (grain) 85 85
Defined daily doses (grain) 83 80
Thousand seed weight (g) 25.8 24.8
Setting percentage (%) 91.5 90.0
Average real product (kg/ mu) 682.4 538
As can be seen from Table 4, after using the rice nutrition liquid of example 2 of the present invention, every mu the highest seedling number of each process increases 3.46-5.0 ten thousand than the nutritive medium of prior art, and number of productive ear increases 3.03-4.75 ten thousand, the percentage of earbearing tiller improves 4.2-5.0 percentage point, and every per mu yield increases more than 65kg.More than analyze and show, rice nutrition liquid provided by the invention can promote to tiller effectively, increases the highest seedling of unit surface and effective fringe, improves the percentage of earbearing tiller, thus reaches the object of many fringes volume increase.
In sum, use rice nutrition liquid provided by the invention, it can significantly improve seedling quality, and make rice shoot leaf look normal, stem foot increases thick, and rooting ability strengthens and dry-matter increases; Can also root growth be promoted simultaneously, increase dry matter weight of hypogeal parts accumulation, and can promote to tiller, increase effective fringe, improve the percentage of earbearing tiller and setting percentage, increase number of grain per ear, thus realize volume increase 11.7%.
Better applied to make the rice nutrition liquid of the embodiment of the present invention one, more effectively be applied in the field of paddy rice soilless breeding seeding, the present invention also provides embodiment two on the basis of above-described embodiment one, embodiment two is making methods that the rice nutrition liquid provided embodiment one is enumerated, now be described in detail and explain, please refer to Fig. 1:
