Effects Of Different Row Spacing And Planting Depth On Potato Quality

Berries, Heilongjiang Academy of Agricultural Sciences, choose the production demonstrationfields as the experimental base, in order to Kexin18and Holland15as experimental material, throughthe different row spacing test and sowing depth study change law of seed in different periods, thetechniques of farming and cultivation mode obtains a set of quality from potato, and the test researchand application in the actual production of.In this experiment, the potato is Kexin18(late) and Holland15(early) as the test materials.Different ridge distance of single factor randomized block design, sowing depth8cm, fertilization of1000kg\/hm~2. Ridge distance was set to75cm,80cm,85cm and90cm, the factors affecting potatoquality, comprehensive influence factors in the orthogonal experiment analysis, to determine the finalseed in the row spacing is the quality of85CM case for the best. Different depth of single factorrandomized block design, the row spacing of85CM, and amount of fertilizer1000kg\/hm~2. Depth wasset to75cm,80cm,85cm and90cm, the factors affecting potato quality, comprehensive influencefactors in the orthogonal experiment analysis, to determine the final seed quality in depth for the8cmcase is the best.Through the research on the quality of the results showed that the potato, potato to avoid lightpreservation has better stability at low temperature, can be stored for a long time, but in the long timeheating or sunlight, easy degradation of infected seed. At the same time, experimental results indicatethat the effect of electrical conductivity, starch content is larger, the depth of water, water, ridge distanceare the stability of the starch content change in different degrees, especially water, ridge distancevariation of starch content play a decisive do use. Changes of starch content with depth is not obviousregularity, also can say the sowing depth had little effect on starch content changes.The application of this technology in the practical production should pay attention to the standardamount of fertilizer. The proportion of nitrogen, phosphorus, potassium fertilizer is1:3:5. In the test ofpotash fertilizer, nitrogen fertilizer for potato production in good seed quality effect, but also a goodway to improve yield excellent. In comparison with other compound fertilizer interaction, the seed hascertain resistance. The technique of farming and cultivation and fertilization method is a technologysystem development prospect of quality and quantity is ideal.
