The relation of ear taste values and fresh ear yield in different treatments could be divided into four types: high taste values and high fresh ear yield, high taste values and low fresh ear yield, low taste values and high fresh ear yield, low taste values and low fresh ear yield.
2. Under the 4 potassium levels designed in this research, seeds on spikes treated with K_2 had the highest content of amylopectin, globulin, soluble amino acid and taste score. The content of soluble sugar was also at a high level.
Thehigh yield of fresh leaves,the proper contents of amino acid,polyphenol,catechin and total sugar in fresh leaves and the best quality of made teacould be obtained when nitrogenous,phosphate and potash fertilizers andrape cake were applied at proper amounts and ratios.
This article introduces a new kind of pipeline measuring technique to replace the industrial X-ray film, using high sensitivity image of special fluorenscent to adjust whole IP, through new data process to make sure the corroded position and the W.
An increase on yield of soybean obtained by different rate of nitrogen application on lessive soils in the eastern part of our province was from 4.4% to 18.42% in average. The optium rate of nitrogen application was N3 which promoted the growth of soybean from the expanding of the first compound leaf to pod filling.Nitrogen rate waa closely related with growth of roots which was promoted with lower rate of nitrogen and inhibited with higher rate of nitrogena pplication. Changes of nitrogen rate influenced w...
Rice is more tolerant of chloride than wheat. If Cl mixed with a moderate rate of 675kg/ha NH_4Cl would not be harmful to the crops It has been found by Various analyses that N, P, Cl do not influence spike length, spike numbers and weight, but they have significant effect on plant height, fresh weight. Cl is no harmful effect on seed quality.conclusion makes it clear that after crops have been harvested, there is some correlativity between the quantity of the remains of N, P, Cl in the soil and the quantit...
The experiment "in Heilongjiang province for 7 trial locations in 1990 proved that the inoculated effect with Azospirillum brasilense increased yield by 286.5 kg/ha, and by 5.2-20.6 %, in average by9.8%, Azospirillum, brasilense can be promote plant growth development, plant height and plant fresg weight increased, also leaf colour turned into green. Analysis of the yield component factors showed that inoculation increased the number of spikes per square motre, the number of grains per spike and 1000-seed w...
