Description
Technical Field
The invention belongs to the technical field of agriculture, and relates to a cucumber seedling culture medium and application thereof.
Background
The industrial seedling raising is a main form of vegetable seedling raising, the annual planting scale of vegetables in China is about 3 hundred million mu according to statistics, the yield is more than 7 hundred million tons, and the annual transplanting seedling demand is 6000-7300 hundred million plants. At present, 3000 intensive seedling farms exist in China, and 3500 hundred million commercial vegetable seedlings are produced in a year. The moss peat and the herbaceous peat are main raw materials of the vegetable seedling substrate and have the advantages of light weight, proper porosity and the like. However, Chinese grass peat is mainly distributed in big and small Khingan areas in the northeast, has high maturity and small particle size, is limited by ecological protection in mining, and has limited mining quantity. As the intensive seedling raising field has huge demand on the seedling raising matrix and higher quality requirement on the seedling raising matrix, the large-scale seedling raising field can use the imported peat matrix with stable quality, and a large number of practical tests on the mixture ratio and quality of raw materials.
Peat, an important component of the carbon reservoir in soil, has been regarded as an important measure for reducing carbon emissions and achieving carbon neutralization, limiting its exploitation. In recent years, screening tests of peat/turf alternative materials are continuously carried out in China, and biosolid wastes such as mushroom residues, rice hulls, cow dung, straws, vinegar residues or vinasse, traditional Chinese medicine residues, river sediment, wormcast and the like are piled up and fermented to be used for preparing seedling culture substrates successively. However, the raw materials of the substrate have various sources and are mostly industrial and agricultural production byproducts, the production process is very different, the physical and chemical properties of the raw materials in different batches have large difference, the seedling quality is unstable, the requirement of high-quality modeling seedling is difficult to meet, and the substrate is difficult to popularize in a large-scale seedling raising field within a short time.
Disclosure of Invention
The invention provides a cucumber seedling culture medium and application thereof, wherein the medium is prepared by partially replacing peat with coconut chaff and garden tree biochar, adding mineral nutrient elements and seaweed extract seaweed essence, and has stable quality, large-scale use and excellent seedling culture effect.
In order to achieve the purpose, the invention provides a cucumber seedling culture medium which comprises peat, nutrient solution reinforced coconut coir and garden tree biochar in parts by volume, wherein the peat, the nutrient solution reinforced coconut coir and the garden tree biochar are mixed according to the weight ratio of 4.5-5.0: 4.5-5.0: 0.5-1.0, and adding water to adjust the water content of the matrix to 55-65%.
Preferably, the peat fibre has a length of 0-10mm and a pH of 5.5-6.5. In the present embodiment, the peat used is imported peat commonly used in industrial seedling, and can be obtained from commercial sources, such as Lasevia peat, Denmark topu peat, Canada FAFAFARD peat, etc.
Preferably, the nutrient solution reinforced coconut coir is prepared by the following method:
adding 4.5-5 kg of desalted coconut husk brick into 20L of cucumber formula nutrient solution containing 4g/L of seaweed extract for foaming, keeping the water content of the substrate at 55-65%, and fully stirring and uniformly mixing to obtain the coconut husk brick.
In the scheme, nutrient solution is adopted in the matrix to strengthen the coconut coir, so that the problems of insufficient nutrients and weak seedling growth in the traditional coconut coir matrix seedling culture process can be effectively solved. Furthermore, the nutrient solution reinforced coconut husk is added with seaweed essence extracted from natural seaweed, which is rich in natural active substances such as seaweed polysaccharide, oligosaccharide, betaine and the like, and proper amount of the seaweed essence can promote the growth of seedling root systems, increase the stress resistance, improve the lumping property of the root systems and is beneficial to cultivating strong seedlings.
Preferably, in the seaweed essence, the mass fraction of alginic acid is more than or equal to 25 percent, the mass fraction of organic matters is more than or equal to 20 percent, and the mass fraction of nitrogen, phosphorus pentoxide and potassium oxide is more than or equal to 20 percent.
Preferably, the cucumber formula nutrient solution at least comprises NO 3 - 11.0～13.0mmol/L、K + 6.0～7.0mmol/L、Ca 2+ 3.2～3.5mmol/L、PO 4 3- 0.8～1.0mmol/L、Mg 2+ 1.8-2.0 mmol/L and B 3+ 0.045～0.050mmol/L。
Preferably, the cucumber formula nutrient solution used in the nutrient solution reinforced coconut chaff is replaced by 0.10-0.12% of macroelement water-soluble fertilizer containing trace elements;
according to the mass fraction, the water-soluble fertilizer at least comprises 20% of nitrogen, 20% of phosphorus pentoxide, 20% of potassium oxide, 2% of magnesium oxide, 0.1% of EDTA-iron, 0.1% of EDTA-manganese, 0.1% of EDTA-zinc and 0.2% of boron.
Preferably, the garden tree biochar is prepared by the following method:
cracking garden trees at 450-500 ℃ for 3-4 h under the anoxic or anaerobic condition, cooling and crushing the obtained cracking products, and sieving the obtained cracking products by a 2mm sieve to obtain the garden trees.
Preferably, the garden trees are trunks, branches or waste materials generated by processing wood and generated by updating and pruning trees in urban or rural greening. In the scheme, the selected ornamental trees include, but are not limited to sycamore, pagodatree, basswood, Chinese white poplar and the like. The biochar from garden trees is added into the matrix, so that the porosity of the seedling raising matrix is improved, the nutrient content of the matrix is increased, and meanwhile, the resource utilization of garden wastes is realized.
The invention provides application of the cucumber seedling substrate according to any one of the technical schemes in large-scale seedling.
Preferably, the seedling of the seedling is a vegetable crop seedling selected from cucumber and tomato.

The soaked seeds were sown in 50-well plates filled with different types of test substrates, and the same substrate was used for the cover material. And (3) placing the plug tray at the temperature of 28 ℃ and the humidity of 90% for shading and accelerating germination for 36-48 hours, and immediately transferring the plug tray to a greenhouse for culture after radicles are exposed so as to avoid overgrowth.
Greenhouse environment: controlling the daytime temperature to be 25-30 ℃ and the nighttime temperature to be 18-22 ℃. After two cotyledons of the seedlings are unfolded, the cucumber formula nutrient solution with the concentration of 1/2 (the EC value is 1.0-1.2) is irrigated every day, and the growth indexes of the cucumber seedlings, including plant height, stem thickness, leaf area, chlorophyll content, overground part and underground part biomass, are investigated after 25 days of sowing. And calculating the strong seedling index and the G value. Wherein:
strong seedling index (stem thickness/plant height) x whole plant stem mass x 100;
g value is the dry mass of the whole plant/seedling raising time.
TABLE 1 Effect of different seedling substrates on the growth of seedlings of the south China cucumber' Lu cucumber No. 3
As shown in the results of table 1, the plant height, leaf area, aboveground and underground biomass and G value of the south China type cucumber 'green cucumber No. 3' treated with the seedling raising substrate (type I and type II) of the present invention were significantly higher than those of the control substrate a, the substrate B and the substrate C. The strong seedling indexes of the type I and the type II matrix treatments are respectively 0.523 and 0.564, which are superior to those of the control matrix treatment.
In order to verify the influence of the matrix on different types of cucumber seedlings, a seedling raising test is carried out by selecting North China bur type cucumber 'Jinchun No. 4'.
TABLE 2 Effect of different seedling-raising media on the growth of the seedlings of North China cucumber "Jinchun No. 4
As shown in the results of Table 2, the cucumber plant height, stem diameter, chlorophyll content, leaf area, aboveground and underground biomass and G value of the seedling raising substrate (type I and type II) are significantly higher than those of the control substrate B, and are close to the growth indexes of the substrate A, the substrate C and the substrate D, and the difference of the partial indexes is not significant. The strong seedling indexes of the I type substrate and the II type substrate are respectively 0.880 and 0.977, the strong seedling indexes are obviously superior to those of the substrate A and the substrate B, and the strong seedling indexes are not obviously different from those of the substrate C and the substrate D.
In addition to the above, efficient production of mechanized transplanting of cucumber seedlings must be considered, and for this reason, the influence of the seedling substrate on the lumpiness of the cucumber seedlings is verified. The method comprises the following steps:
the cucumber seedlings were allowed to freely fall at a height of 80cm, and the scattered matrix rate was calculated from the ratio of the weight of the scattered matrix to the original weight.
TABLE 3 influence of different seedling substrate treatment on the scattering substrate rate of cucumber seedlings
From the results in table 3, it can be seen that the difference of the scattered substrate rate of cucumber seedlings cultivated by each seedling substrate is large, wherein the substrate rate of substrate C scattered is the lowest, the substrate rate of the invention is equivalent to that of substrate B, and the substrate rate of substrate a scattered is relatively high but not more than 20% (the scattered substrate rate > 20% indicates that the substrate is scattered and lump, and is not suitable for mechanized transplanting).
Therefore, compared with the current commercial matrix, the matrix composition (I type and II type) can promote the growth of cucumber seedlings, improve the strong seedling index and is beneficial to culturing strong seedlings. The seedling raising effect of the two matrixes is obviously better than that of a control matrix or equivalent to that of the control matrix, and especially the seedling raising effect on south China cucumbers is better than that of the control matrix. In the aspect of adapting to the characteristic of mechanized transplanting, the matrix scattering rate of the invention is controlled between 2 percent and 3 percent, is slightly larger than the contrast matrix C, and completely meets the requirement of mechanized transplanting.
The substrate can also be used for tomato seedling culture, as shown in the results in table 4, the plant height, stem thickness, leaf area, biomass of overground part and underground part, strong seedling index and G value of tomatoes treated by the seedling culture substrate (I type and II type) are all obviously higher than those of the control substrate B, and are close to each growth index of the substrate C, and the difference of partial indexes is not obvious. The strong seedling indexes of the I type matrix and the II type matrix are 1.008 and 0.909 respectively, the strong seedling index is obviously superior to that of the matrix B, and the strong seedling indexes are not obviously different from those of the matrix A and the matrix C.
TABLE 4 Effect of different seedling substrates on the growth of tomato '72-69' seedlings
According to the application tests, compared with the existing domestic seedling raising substrates (seedling raising substrates A and B), the seedling raising time of the cucumbers is 12-24 hours in advance, the growth speed in the seedling stage is high, the seedling growing period is short, and the seedling raising standard can be reached 25 days after sowing. Compared with imported peat substrate commonly used in industrialized seedling raising, the emergence time is equivalent to the seedling time, but the substrate adopts natural coconut chaff and garden waste biochar to partially replace peat, so that the dependence on imported peat resources can be reduced, and the method has the advantages of wide sources, environmental friendliness, easiness in large-scale popularization and use and the like.
