The present invention has following good effect compared with prior art:
1, selects matrix the most cheap in the soilless culture-mountain sand or river sand for use, not only make production cost reduce (1 yuan of vermiculite per kilogram greatly, every cubic metre of 10-13 unit of perlite), and husky matrix can oppress potato base pitch and root effectively and produce more stolon (knot potato skill).According to studies show that of the applicant, in evaporation discharge big summer, as transplanting medium, its root system development is not as husky matrix with vermiculite.Because keep humidity to need constantly water spray, and the moisture holding capacity of vermiculite is too strong, causes the supersaturation of cuttage seeding root moisture, is unfavorable for root system development on the contrary.Husky matrix moisture capacity is between vermiculite and perlite, and liquid manure utilizes benefit better, and relatively near natural soils.
2, cut the segment of root, in fact all leaf segments all growing more or less has aerial root (adventive root), even if the young plant that seedling age is short, in a single day they touch matrix moist and through sterilizing, under the relative moisture conditions of higher, took root in general 7 days, even if microthermal climate (5 ℃ of liquid temperature, daytime, temperature was about 10 ℃), also be no more than 10 days, survival rate is all more than 95%, without the young plant that taking root liquid soaks and dark cultivation is taken root, root of hair speed is slow relatively, and the root amount is less, but helps the g and D of stolon.Soak direct cuttage with clear water, can effectively prevent from the wilting phenomenon that occurs because of human factor (it is untimely to water) after the young plant cuttage to make simple to operateization, also reduced cost, the saving of labor saves time.
3, directly plant on the seedbed, ground, can make full use of matter source, soil, plow layer simultaneously is deeper, help young plant knot potato, improve and finish the potato number, reduced the spending (about each 12 yuan of seedling-cultivating trays, wanting 3500-6000 seedling-cultivating tray for 1000 square metres) of seedling-cultivating tray, make simple to operateization, cost has also reduced simultaneously.
4, preserve moisture with the method for adding a cover shade net, can effectively reduce the temperature of Wembledon tennis open competition chamber, cooperate and spread the purpose that water reaches manual adjustment Wembledon tennis open competition chamber relative moisture, under the condition of sheltering from heat or light, be beneficial to growing ahead of time of young plant stolon, and reduced cost.
5, the test-tube plantlet cuttage cycle long, unit are density is higher, knot potato number is many, quality is good, can effectively reduce artificial cuttage, sterilization and continuous cropping number of times, the saving of labor, saves time, economizes fertilizer.The subculture growth of cuttage seedlings cycle is short, and knot potato number is few, but the density of unit are is higher.
6, individual plant knot potato number is many, is beneficial to stronger area and the department of seasonality that only produced a batch in a year and produces, and 1 square metre of output of planting one batch is equivalent to the 1 square metre of output in 1 year of Tianjin Vegetable Research Institute patent application technology, and efficient, high yield, cost are low.
7, commodity grain number many (every heavy 〉=1 the gram be the commodity grain), the economic benefit height.
8, the preparation of nutrient solution adopts agricultural to go up widely used composite fertilizer and individual event chemical fertilizer substantially, because required other the necessary micro-composition of cuttage seeding is too many, and the impurity in the as fertilizer sources exists, substantially nutritional deficiency disease can not occur with this simple nutrient solution, thereby reach the purpose that the nutrient solution preparation is convenient, material is easy to get, reduces cost.
