| This experiment is one part of such as Professor Yang Qiusheng had undertaken 948 national projects - the new compression matrix and breeding technology.Repap mainly the United States and Stuewe & Sons-owned companies control jiffy products, jiffy peat-based products are expected to be complemented by other filler, according to the nutritional needs of plant growth on the composition of a certain formula, the use of molding jiffy non-woven mesh and the shape of the production of certain matrix products nursery. Corn stalks and then come up to the main fermentation substrate, together with the other in favor of the cultivation of plant growth medium, through independent research and development or the introduction of the molding machine and compressor for compression, in favor of product storage, transportation, water and relatively good water retention, nutrition the release of a rich and lasting culture of the new matrix.The former two experiments on the basis of culture continue to be mixed media filter, select a great impact on the nutrient composition of the humic acid, the nature of high-impact compression binder, mixed-impact matrix of physical and chemical properties of vermiculite, can impact absorbent coconut husk, corn stalk fermentation PH value matrix SSP five high-impact media fermented with corn stalks for orthogonal test matrix. The experimental results are as follows:1)This experiment is on the basis of the first of two experiments and a step further research, through the cultivation on matrix compression medium - humic acid, clay, vermiculite, coconut husk, SSP and corn stover fermentation matrix, Which used the methods with orthogonal test screening test mixture and high-impact on physical and chemical properties of substrate, plant growth, and mixed into the formula with nursery container machine (Shandong Academy of Forestry Development) and self-molding the compactor, and import products jiffy matrix contrast test. In the molding process, the mixed matrix is not dry and wet, only about 50% water content to normal production.2)Different treatment of the substrate after forming the structure of the difference between its larger, and some loose and full uniform, some caking uneven thickness, which has some relationship on contain a certain amount of how much clay in matrix formulations. the Extrusion using different levels of compression and found that 1 ton of the most appropriate level of compression matrix, forming matrix 6cm±0.5 in the high rough 4cm±0.5 compressed into the high rough 3cm±5 and 4.5±5cm, high water-swelling after 5 cm±0.5 and rough 4 cm±0.5, only vertical expansion of 1.67 times, but jiffy products 8 to 15 times.3)Different plant species's cultivars Rooting and growing have different requirements for the Culture Media. Poinsettia in dealing with 2 (corn stalk matrix: SSP: humic acid: binder: vermiculite = 15:0.2:0.4:3:4 ), 6 (corn stalk matrix: humic acid: SSP: binder: vermiculite = 15:0.3:0.6:1.5:4), 8 (corn stalk matrix: SSP: humic acid: binder: vermiculite = 15:0.4:0.4:1.5:5) and Ligustrum vicaryi in dealing with 1 (corn stalk matrix: SSP: humic acid: binder: vermiculite = 15:0.2:0.2:1.5:3), 7 (corn stalk matrix: SSP: humic acid: binder: vermiculite = 15 : 0.4:0.2:4.5:4) have the same higher rooting rate with the peat; Poinsettia in dealing with Ligustrum vicaryi 2,3,6,8 and 1,6,8 with peat in the same culture with the effect that they have the same is more appropriate for -6 and 8 of the deal.4)Different varieties of plants'growth and seedling roots have different requirements for the matrix, Orientalis in dealing with 2(corn stalk matrix:cly:vermiculite: coconut husk =1000:10:30:10),3(corn stalk matrix:cly:vermiculite: coconut husk =1000:10:50:15),8(corn stalk matrix:cly:vermiculite: coconut husk=1000:50:30:5) and 3(corn stalk matrix:cly:vermiculite: coconut husk=1000:10:50:15),4(corn stalk matrix:cly:vermiculite: coconut husk=1000:30:10:10),5(corn stalk matrix:cly:vermiculite: coconut husk=1000:50:30:15),8(corn stalk matrix:cly:vermiculite: coconut husk=1000:50:30:5) altissima in dealing with the same control with a better survival rate; orientalis in dealing with Ailanthus altissima in dealing with 2,3,6,8 and 5,6, 7,8 with the control culture with the same effect, they have the same processing is more appropriate for -6 and 85)Matrix through the corn stalks and superphosphate, humic acid, bentonite, vermiculite mixed and through leaching can be better cuttage matrix, and nutrients to maintain good long-term and longer to meet the plant time the growth of demand and the results of previous studies is consistent 6)Matrix through the corn stalks and superphosphate, humic acid, bentonite, vermiculite, coconut husk mixed after planting seedlings, as a lower survival rate matrix, this may be due to its high value caused by the EC, not seed germination in the matrix so as culture growth can replace peat matrix.7)Survived through the growth of cuttings of view, to deal with 3,8 showed a strong ability to relieve fertilization on the corn stalk matrix: SSP: humic acid: binder: vermiculite to 15:0.2:0.6:4.5 : 5 ratio of good to 15:0.4:0.4:1.5:5 followed by the ratio of long-term to meet the growth of plants.8)Cuttings and seedlings from the planting of corn stalk screening test matrix formulations of view, as a culture medium, has its own advantages and disadvantages, including the cultivation of the public think that the best matrix - peat, there are deficiencies, only through the cultivation of different Mixed media can complement each other weaknesses and become better cultivation matrix... |
