s：Onion seeds at room temperature for five years in sand storage as the experimental material,with matrix sowing, antioxidant system and its seedling stage storage substance content changes were determined, we studied physiological and biochemical changes in the storage aging process, and explored the sand onion seed longevity and the factors that affect its life to provide theoretical basis and the instruction for its seed storage and production.The results showed that content of malondialdehyde （MDA）,generation rate of superoxide anion radical （O2-） decreased at first,then increased with the extension of storage time.activity of superoxide dismutase （SOD）,catalase （ CAT） and content of soluble sugar increased at first,then decreased.

The physiological indexes of leaves of Pugionium cornutum （L.） Gaertn. seedlings under artificial simulation drought stress conditions were determined by using leaves of annual Pugionium cornutum （L.） Gaertn.seedlings. The results showed that under mild drought stress conditions,the relative water content of sand was 4.4 percent point less than that of control;under moderate drought stress conditions,the relative water content of sand was 27.45 percent point less than that of control and the reduction was obvious;under severe drought stress conditions,the relative water content of sand was only 18.23%.The nature saturation deficit of Pugionium cornutum （L.） Gaertn.seedlings was gradually increased and was significantly higher than that of control （P〈0.01）.The increase of the nature saturation deficit of Pugionium cornutum （L.） Gaertn.seedlings was observed under mild drought stress conditions,and the nature saturation deficit under moderate and severe conditions were 0.32 percent point and 54.2 percent point higher than that of control, respectively.With the aggravation of drought stress,the available free water content of Pugionium cornutum （L.） Gaertn. leaves was gradually decreased.Under mild and moderate drought stress conditions,the tendency of the decrease was relatively slow,and the available free water content was 8.9 percent point and 15.2 percent point less than that of control,respectively. However,under severe drought stress conditions,a significant reduction of available free water content was observed （P〈0.01）.The irreducible water of leaves of Pugionium cornutum （L.） Gaertn.seedlings was gradually increased.Under mild drought stress conditions, the irreducible water was significantly higher than that of control （P〈0.05）. However,no significant increase of irreducible water were observed under moderate and severe drought stress conditions（P〉0.05）.

With the comprehensive evaluation of method to evaluate anti-drought of deep groove and slope Cerasus humilis, 5 physiological indexes of Cerasus humilis for drought-resistance in natural environment were determined to study in 2 kinds of the different site conditions, included in malondialdehyde, SOD activity, chlorophyll content, the cell membrane permeability, leaf relative water content, The main results were as follow： the Cerasus humilis of deep groove drought resistance surpassed the Cerasus humilis of slope.This research provided strong theoretical basis for better utilization of Cerasus humilis traits.

The aim of the present study was to investigate the changes of ultra-weak luminescence during the process of strawberry fruit development and maturation and its relationship with the development and maturation of the fruit. The chlorophyll content, fruit firmness and titratable acidity showed a increasing tendency, however, the anthocyanin content, soluble solids content and soluble sugar content showed a decreasing tendency. Furthermore, the ultra-weak luminescence strength was found to decrease with the development and maturation of the fruit. Significant positive correlation was observed in chlorophyll content and fruit firmness and ultra-weak luminescence strength, however, significant negative correlation was found in anthocyanin and soluble sugar content and ultra-weak luminescence strength. It was indicated that the UWL strength was gradually decreased with the increase of maturation degree of the strawberry fruit.

Apocynum seeds as experimental materials,their morphological characteristics were observed, and the different antibacterial treatment, different light conditions and different soaking time on seed germination were researched.The results showed that the seeds of apocynum was ovoid oblong,brown,surface striolate,white silky hairs at the top, which was 2.437 mm long,0.681 mm wide, thickness of the seed coat 0.015 mm, seed size index 0.025. Sterile water treatment had the highest germination rate, as antibacterial reagent was appropriate;light conditions on the germination rate of apocynum effect was not significant, in contrast, apocynum seeds were suitable to germinate in natural light conditions.The seed germination rate and germination potential were highest in 8h, germination time was the shortest, seed soaking treatment should be keep 8 h.

s：In order to find wilt inducible resistance chemical reagent of the sunflower verticillium,we selected the K2HPO4, sodium silicate,benzene and BTH,salicylic acid,chitin,glucan for the bacteriostasis experiment and resistance agent screening test in vitro,the test results showed that the K2HPO4,chitin,sodium silicate bacteria,dextran had no antagonism on Verticillium dahliae Kleb at antibacterial test in vitro. oxalic acid had no antagonism when it was below 100mg/L concentration.The resistance agent screening text results showed that potassium silicate and oxalic acid had good inducible resistance to the sunflower verticillium wilt.

The relationship between soil moisture during spring sowing and meteorological conditions were comprehensively researched with the observed data related to soil moisture content and meteorological conditions during ten continual growing seasons from 2005 to 2014 in Chifeng.The results showed that the precipitation, sunshine, temperature, wind speed before spring sowing period and in autumn have the same dynamic changes, but evaporation has different dynamic changes.The regional distribution of soil moisture in south of Chifeng is better than in north of Chifeng.For five meteorological factors, precipitation very significantly positive correlated with relative soil moisture,and the simple correlation coefficients were 0.411,0.358,respectly before spring sowing period and in autumn,evaporation significantly negative correlated with relative soil moisture,and the simple correlation coefficients were-0.216,-0.269,which implied precipitation and evaporation were the most important factors in determining soil moisture in spring sowing period.

The micro-climate characteristics of greenhouse in the continuous cloudy days were analyzed,which was based on automatic weather station data in the greenhouse and meteorological data outside the greenhouse.The results were as follows, during the continuous cloudy days in winter, both the air temperature and the ground temperature in the greenhouse gradually were decreased.The temperature difference between in and outside the greenhouse was reduced.So did the ground temperature difference.The Relative humidity in the greenhouse showed periodic change.The value was high,which in and outside greenhouse gradually tended to be the same.The production managements should focus on keeping warm,increasing temperature,supplying illumination and enhancing stress resisitance.

The occurrence and development causes of a severe rainfall weather process that happened in Hexigten Banner from June 5th to 7th 2014was revealed in this article. The results showed that upper-level low vortex was the main influence system for this weather process, Blocking function of Okhotsk Sea blocking high made the system move slowly and last for a long time, The invasion of upper dry cold air and the coupling of upper and lower jets provided abundant moisture and strong ascending motion for this rainfall process.

The variation characteristics of frozen soil in recent 49 years and frost free period in recent 55 years were analyzed based on the data collected from meteorological observation of Wuchuan County from 1960 to 2014. A general decreasing tendency of annual maximum frozen soil depth and a general increasing tendency of "non frozen soil period"and frost free period were observed in this study. Based on the data of first date of frozen soil, the last date of frozen soil, the first date of frost free period, the last date of frost free period and other factors, the variation characteristics of frozen soil and frost free period were detailed analyzed.
