Residues of demeton on apples were studied by the cholinesterase activity inhibition method of Hestrin. Three treatments were conducted with a 50% demeton emulsifiable concentrate at a dilution of 1:1,000: (1) only the fruits on a branch were dipped in the insecticide solution; (2) branches with fruits and leaves were sprayed while the fruits were wrapped with plastic sheets; (3) a branch with fruits and leaves with the cut end set in the insecticide solution for twenty-four hours and then in water.

Residues of demeton on apples were studied by the cholinesterase activity inhibition method of Hestrin. Three treatments were conducted with a 50% demeton emulsifiable concentrate at a dilution of 1:1,000: (1) only the fruits on a branch were dipped in the insecticide solution; (2) branches with fruits and leaves were sprayed while the fruits were wrapped with plastic sheets; (3) a branch with fruits and leaves with the cut end set in the insecticide solution for twenty-four hours and then in water. After the treatment the fruits were examined for demeton residues. A summary of the results is given as follows: (1) Fruits that were dipped in the demeton solution for 1 minute were found to retain a residue as high as 2 ppm and dropped to 0.75 p.p.m, after twenty-four hours. The residue gradually fell to zero within two weeks or so. (2) Within twelve days after the spraying of the leaves, residue on the fruits was not detectable. (3) Within twenty-four hours during which the branch was set in the insecticide solution, although the branch had absorbed much of the solution, no residue was detectable in the fruits. On the next day, a residue of 0.5 ppm was detected, and then it dropped to zero within ten days. It may be supposed that when demeton is applied by spraying, as generally the case, the residue may be chiefly due to the retainment of insecticide on the fruit surface, and the residue rapidly reduce below a tolerance of 0.75 ppm within a few days. The author suggests that the period between the latest application of the insecticide and the harvest time may be shortened to three or four weeks.

用Hestrin胆硷酯酶活性测定法,系統研究以不同方式施用内吸磷(E-1059)后,苹果内吸磷残留量的动态变化情况。施药方式有三种:(1) 浸果—仅对树上的苹果进行药浸,树叶和树枝不接触药液。(2) 噴叶—苹果以塑料膜包好后向树上嘖药,只树叶和枝上着药,而苹果不着药。(3) 浸枝——将带有果和叶的一段树枝剪下,断端浸入药液中迫使吸收药液24小时。检测結果:浸果施药后第一天内,苹果可检测出很高的内吸磷残留量(可达2 ppm左右),1天后残留量降到0.75 ppm以下,两周后残留量可降低到接近零;噴叶施药后12天内,經数次检测,均未发现有内吸磷残留;用药液浸枝,虽然第一天树枝吸收了不少的药液,但苹果中几乎检測不出内吸磷的残留,第二天换以水浸枝,却反而检测出内吸磷残留量(将及0.5 ppm),大約10天左右残留量降到接近零。試驗結果说明:一般噴雾时内吸磷的残留主要是由于药液直接接触苹果果皮所致,通过叶和枝内吸輸导至苹果上的药液是微乎其微的;浸果施药后第一天内残留量最高,以后逐漸降低,約两周后降到接近于零;浸枝时迫使吸入药液,但輸导至苹果上的药物甚少,并且内吸輸导需要一定时間,所以第二天残留量最高。关于苹果施用内吸磷...

In the study,the testing results for levelling and transforming shifting sand dunes with pumping irrigation of the Yellow River water and for preventing water from infiltration with bedding plastic sheets underlying the dunes are summerized. The testing results indicate that 22 cm of topsoil is formed on surface after 15 years'irrigation. Pure sand soil is changed into arable soil by planting crop and Leguminosae spp. and by usin g fertilizers. The plastic sheets are applied for keeping good moisture...

In the study,the testing results for levelling and transforming shifting sand dunes with pumping irrigation of the Yellow River water and for preventing water from infiltration with bedding plastic sheets underlying the dunes are summerized. The testing results indicate that 22 cm of topsoil is formed on surface after 15 years'irrigation. Pure sand soil is changed into arable soil by planting crop and Leguminosae spp. and by usin g fertilizers. The plastic sheets are applied for keeping good moisture in the irrigated area and per unit area yield of sobean and maize increased 277.8% and 238.4% separately. The height and diameter of seedlings of sand-holding species (Ammopitanthus mongolicum, Biota orientalis) also increased in compari-son with that in the area without any artificial measures.

本文重点总结了我国在宁夏中卫腾格里沙漠中,平整流动沙丘引黄淤灌改良流沙地及在流沙地铺设隔水层的试验结果。试验表明,经引黄淤灌15年后,可沉积淤泥厚达22厘米。通过施肥、种植农林植物等措施,使原来单相流沙改良成为有层次的耕作土壤。经淤灌并加薄膜塑料隔水层后,所种植的农林作物增产效果显著,与对照相比,黄豆增产277.8%,玉米增产238.4%。一年生沙冬青苗高生长增加165%,地茎粗增加200%,二年生侧柏幼苗高生长增加163%,地茎粗增加79%。
