Large seed cucumber and small-sized seed tomato are selected in test, and kind is as follows respectively:
Cucumber: spring four F1; Tomato: hair powder 802.
Seedling pan: 25cm * 50cm seedling pan, totally 50 cave/dishes are selected in test.
4, process
Test arranges 3 processing altogether, is respectively:
Process 1: the peat composed of rotten mosses: vermiculite: perlite=5: 4: 1 (contrast)
Paper mill sludge biological compost: vermiculite: perlite=5: 4: 1
Process 2: the peat composed of rotten mosses: vermiculite: perlite=4: 5: 1 (contrast)
Paper mill sludge biological compost: vermiculite: perlite=4: 5: 1
Process 3: the peat composed of rotten mosses: vermiculite: perlite=3: 6: 1 (contrast)
Paper mill sludge biological compost: vermiculite: perlite=3: 6: 1
Annotate: above ratio is volume ratio, after ratio prepares, all is added into 1kg/ cube function yeast again in above-mentioned 3 seedling mediums with the processing of paper mill sludge biological compost.
Two, operation and management
1, the seedling medium proportioning is mixed: the various seedling mediums that will select are by above-mentioned volume ratio proportioning, and are stand-by after fully mixing;
2, sabot: with the abundant mixed seedling medium seedling pan of packing into, vibrate gently and make under several in the cave seedling medium relatively more closely knit, then strike off in length and breadth with scraper plate, it is stand-by that seedling medium is uniformly distributed in the dish;
3, vernalization: 1-2 day is carried out vernalization to seed before sabot, germination time according to concrete vegetable seed sprout speed and decide, showing money or valuables one carries unintentionally with seed in principle is as the criterion;
4, sowing: sow after seed shows money or valuables one carries unintentionally, generally carry out the fine morning, depth of planting is generally 0.5cm, can not be too shallow or too dark, in case seed is not emerged or the seed belt cap is unearthed;
5, management: before the sowing seedling medium gradation in the seedling pan is watered permeablely, the seed front seedling pan humidity of not emerging will remain on about 90%, will suitably reduce seedling pan humidity after cotyledon flattens, and in order to root growth, morning and evening every day is respectively watered water one time.
Three, result's contrast
1, the different vegetable seed reguarity condition survey of sprouting:
1. the vernalization seed is sown into behind the seedling pan the 3rd day, institutes an inquiry the seed sprouting situation, and whether the reguarity that main investigation is emerged, cotyledon stretching, extension situation etc. are excessively high with permeability, the degree of packing and the inorganic salt concentration of judging seedling medium.Table 1 is the situation of sprouting of the 3rd day each seed of processing of cucumber after broadcasting, as can be seen from Table 1, cucumber seedling rate in each processing take the peat composed of rotten mosses as seedling medium is 100%, and the seedling rate in compost treatment is low, but the reduction along with the compost usage ratio, bud ratio then progressively improves, and especially when the compost usage ratio was 30% or 40%, the situation of sprouting was identical with the contrast peat composed of rotten mosses.
2. in broadcasting rear the 6th day the tomato situation of emerging is investigated, each leaf emergence of peat composed of rotten mosses matrix is 98%, and the tomato seedling rate is processed a little less than the peat composed of rotten mosses in the compost treatment, but along with the ratio of compost in the compost treatment reduces, the tomato seedling rate is higher.When the compost ratio was 30% or 40% in the compost treatment, the tomato seedling rate was processed identical with the peat composed of rotten mosses.
After broadcasting, respectively processes by table 1 the seed situation of sprouting
2, emerge growing way, the appearance situation of rear rice shoot
As can be seen from Table 2, about the 7th day after emerging, rice shoot grows gradually rough leaf and growth is accelerated.With regard to cucumber, because its seed is large, nutritious, the nutrition that the growth of rice shoot relies on seed to bring fully in the rear short period of time of emerging, the seedling growth situation determines by seed nutrition; Therefore, this moment rice shoot all show as the leaf look dark green and healthy and strong.Different from cucumber is, after tomato emerges the 7th day the time, the leaf look of tomato was dark green during all were processed, but the tomato strain height that the peat composed of rotten mosses is processed is apparently higher than compost treatment.Interpolation of this explanation compost is stronger to growth-inhibiting effects such as seedlet crop such as tomatoes, but when the compost ratio is reduced to 30%, the growth-inhibiting effect of tomato sprout is obviously weakened.
Table 2 is broadcast rear the 7th day and is respectively processed growing way appearance situation
3, when seedling growth to the in the time of 14 days, the cucumber seedlings in the peat composed of rotten mosses matrix is withered gradually, and true leaf begins yellowing, a little less than growing way turns, shows that the nutritive ingredient in the peat composed of rotten mosses matrix runs out of gradually, need to replenish the required nutritive element of seedling growth in the mode of fertilising.With regard to all compost treatment, rice shoot leaf look dark green, and the growth impetus strengthens, and the compost ratio processing of this moment below 50% all demonstration promotes cucumber growth.With regard to tomato, the tomato growth during all peats composed of rotten mosses are processed the 14th day the time after broadcasting is normal, and the leaf look shows slightly sap green, is down to 50% when following when the compost ratio, and compost is eliminated to the restraining effect of tomato growth in earlier stage, and shows as tomato promoter action significantly.Leaf look in these several processing this moment is emerald green, and leaf area is large, and the stem strain is sturdy, and robust growth is as shown in table 3.
Table 3 is broadcast rear the 14th day and is respectively processed growing way appearance situation
4, after broadcast the 21st day the time, the peat composed of rotten mosses processes respectively that the jaundice of cucumber seedlings leaf look, plant are thin and tall, growing way very a little less than, and compost each process in the equal growing way of cucumber seedlings healthy and strong, the leaf look bud green, the stem strain is sturdy.Cucumber seedling Ye Selve yellowing shows as a small amount of fertilizer deficiency in 30% compost treatment.At this moment, the rice shoot growing way is best, as shown in table 4 in 40% and 50% liang of compost treatment.
When broadcasting rear the 21st day, tomato seedling Ye Selve yellowing in each processing of the peat composed of rotten mosses, growth turns slow.At this moment, tomato leaf look bud green, sturdy, the robust growth of stem strain is as shown in table 4 in each compost treatment.
Table 4 is broadcast rear the 21st day and is respectively processed growing way appearance situation
5, test enters the 28th day, and as shown in table 5, it is all withered and yellow that the peat composed of rotten mosses is respectively processed cucumber seedlings bottom leaf, can't normal growth, and this moment, and except the jaundice of 30% compost treatment Folium Cucumidis sativi look, each processes all the other compost and all shows as leaf look bud green, robust growth.Wherein, best with 50% compost treatment cucumber seedlings aggregate performance, its plant single-strain fresh weight is 2.84g/ strain (contrast is the 2.13g/ strain), and dry-matter is 0.25g/ strain (contrast is the 0.20g/ strain), and is as shown in table 6.
At this moment, because the basic approach exhaustion of nutrition in the peat composed of rotten mosses, the peat composed of rotten mosses is respectively processed tomato bottom Ye Yese and is turned to be yellow, a little less than growing way obviously turns.In each processing of compost, 50% processing tomato plant single-strain fresh weight is 1.16g/ strain (contrast is the 0.4g/ strain), and dry matter weight is 0.1g/ strain (contrast is the 0.03g/ strain), shows as best, as shown in table 6.
Table 5 is broadcast rear the 28th day and is respectively processed growing way appearance situation
Table 6 is respectively processed single-strain fresh weight and dry matter weight (unit: gram) in the time of the 28th day
