查询词典 fertilization

Low table in the conservation zone and the ball Road area, the high point of Hawaii for regular cultivation, its fertilization slightly more crop cycle, but only one year as opposed to the maintenance of a city is often green grass, crop fertilization "usage and frequency 6-7 times more."

No evident regularity was found in the depth from 15 to 30 cm. There was an obvious accumulation of OM and TN in the top 30 cm of the fallowed soils, of which the accumulation of OM was faster than that of TN and there was more accumulation in no-tillage compared to tillage. Soils applied with inorganic and organic fertilizers had much more OM and TN at 0～5 cm and 5～15 cm depth than soils applied with only inorganic fertilizers and soils without fertilization. However, OM and TN in these treatments were less than that in fallow treatment. No significant differences in OM and TN contents were found between fertilization treatments. Only in the 5 cm of top soils, OM and TN of the soils treated with only inorganic fertilizers were more than that of CK.

长期休闲的土壤在整个耕层有明显的有机质和氮素累积，其中碳的累积快于氮的累积，免耕条件下比耕翻条件下累积量更大。0～5 cm和5～15 cm土层有机肥与无机肥配施的处理，其有机质和全氮质量分数均显著高于单施化肥处理和不施肥处理，但均低于休闲处理；15～30 cm土层各培肥处理则无明显差异；单施化肥的土壤有机质和全氮质量分数高于不施肥处理，但这种差异只在表层（0～5 cm）较显著。

GIFT is again the removal of the oocyte from the ovary, but instead of fertilization outside the body, the egg and sperm are mixed together, placed into the fallopian tube, where fertilization and embryo development take place (this is where the sperm and egg normally meet).

GIFT也是从卵巢取出卵母细胞，但是并不是在体外进行受精，而是将卵和精子混合在一起，送回到输卵管，受精和胚胎发育是在那里进行的（这就是正常情况下卵和精子相遇的地方）。

Y. Also seen from current content of phosphorus in soils, even less fertilization or no fertilization may ensure good harvest of paddies.

同样以现有土壤含磷量看，即使少施或不施磷肥，也可保证水稻的较好收获。

The field experiments were conducted to study on the effect of different N, P2O5, K2O fertilization rate and ratio on nutrient status and tuber yield of potato in three potato production bases. According to traditional application rate, N-P2O5-K2O =300-345-375 (kg/hm2), the fertilization rate of N, P2O5, K2O was decreased to 180, 180, 225 kg/hm2, respectively.

试验分别在甘肃省景泰县、内蒙古自治区达拉特旗和河北省沽源县3个马铃薯生产基地进行，在基地常规N、P2O5、K2O肥施用量分别为300、345、375kg/hm2的基础上，研究改变磷、钾、氮肥用量对马铃薯营养状况、块茎产量以及土壤养分的影响。

Currently as China's accelerating development of agricultural industrialization and the increase of the agricultural production investment, the demand for chemical fertilizers increases year after year. Simultaneously as China's scientification in fertilization and fertilization ratio of the nitrogen, phosphorus, and potassium fertilizer tending to be reasonable, the chemical fertilizer demand structure will possibly change, the chemical fertilizer market environment will also change, the chemical fertilizer industry will run to the direction of high efficiency and environmentally no harm. Comparing to ordinary urea, large urea has many merits. These merits include big rime, glabrous pellet, smooth and well-mixed, not easy to crush or agglomerate in moist environment, suitable for long distance bulk transport and storage, and so on.

目前随着我国农业产业化的不断加快发展和对农业生产投入的增加，化肥的需求量在逐年上升，同时随着我国农业施肥的科学化，氮、磷、钾肥的施用比例趋向合理，化肥需求结构可能发生变化，化肥市场环境也会发生变化，需求旺盛的化肥业将向高效、环保等方面转化；大颗粒尿素与普通尿素相比，具有结晶大、颗粒光洁、圆滑、均匀，不易粉碎和吸潮结块，具有适合长途散装运输和存贮等优点。

Under conventional N fertilization and irrigation condition, N2O emissions during 2001-2002 and 2002-2003 in winter wheat and summer maize rotation system were 1959 g N hm-2 and 1250 g N hm'2, respectively; and 68%-86% of N2O emission occurred in summer maize growth season, the emissions mainly occurred in 2 weeks after N fertilization and irrigation. The highest flux rates were 5.06 mg m-2 d-1 and 5.60 mg m-2 d-1 in the rotation period of 2001-2002 and 2002-2003, which were happened at the ten-extended leaf stage in summer maize season when top-dressing N fertilizer was applied.

在冬小麦／夏玉米轮作体系农民传统的水肥管理处理中，2001-2002和2002-2003两个轮作周期内测得的N_2O的排放量分别为1959 gN hm~(-2)和1250 gN hm~(-2)，N_2O的排放主要集中在每次施肥和灌水之后的两周内，其中夏玉米十展叶期追肥后两周内N_2O的排放速率最高，2002年和2003年分别达到5.06 mg m~(-2)d~(-1)和5.60 mg m~(-2)d~(-1)。
