The gradual migration of rural population to cities is an inevitable result of the sustainable development of China's society and economy. Going out to work is not only a personal behavior of farmers in line with this historical trend,and in the present moment,it is also an important measure to win the battle against poverty. Xundian Yi and Hui Autonomous County is located in the northeast of Yunnan Province. It is one of the key counties in China's poverty alleviation and development work. Through the implementation of special measures to increase labor income,a total of 125 611 rural laborers were employed from 2014 to 2018,and as a result,a large number of farmers have been lifted out of poverty. However,under this model,the transfer of a large number of rural laborers also has an impact on the utilization of contracted land of migrant households,mainly demonstrated by land abandonment,decline in land use efficiency and decline in land productivity,which are not conducive to the sustainable use and protection of land resources. To this end,based on field research,this article analyzes the changes in the utilization of land of migrant households under the poverty alleviation model of working outside,as well as their impact. In addition,the questionnaire survey of the registered poverty-stricken households show that the area and productivity of land owned by households with migrant workers are on a downward trend compared to those before and those of households without migrant workers. Land transfer is a feasible means to solve this problem and to consolidate the achievements of poverty alleviation and sustainable use of land resources. It is suggested that great attention should be paid to the contract and management issue of land left by migrant households,establishment of efficient guarantee mechanism,improvement of land utilization and promotion of saving and intensive use of land resources to bring the land resources to their proper value.

At present,there are many problems in the self-circular development model of " land transfer-real estate development-land financeurban sprawl" in China. The endogenous power of policy implementation is insufficient,the top-level design is not systematic enough,the departmental linkage mechanism is flawed,the local basic data is weak,and there are difficulties in technical operation. According to the current situation,this paper puts forward the following policy suggestions: based on the establishment of financial transfer payment mechanism in rural areas,the construction of the system of man,land and money should be promoted in coordination,and a scientific monitoring system of urbanization degree should be established,so as to make up for the deficiency of the slow speed of " man urbanization" and make the new urbanization healthy and sustainable.

Land use regionalization is a strategic measure for the rational use,management and protection of land resources based on local conditions. Based on the needs of targeted poverty alleviation and rural revitalization strategy and the analysis on the natural and socioeconomic conditions,characteristics of land resources,and the current status of land use in Luquan County,corresponding regionalization indices were selected from four aspects: economic environment conditions,socioeconomic conditions,land resources and land use structure,and poverty alleviation and development level,a scientific and feasible index system for land use regionalization was constructed,and land use in Luquan County was regionalized by using systematic cluster analysis method. The results show that the 16 townships( towns) of Luquan County were divided into four land use regions,poverty alleviation region for development of new town and characteristic industries in the southwest( I),agricultural development and ecological poverty alleviation region in central mountainous area( II),poverty alleviation region for development of characteristic agriculture and tourism towns in eastern plateau mountainous area( III),and poverty alleviation region for development of characteristic industries and protection of land economy in the northern alpine valley area( IV). In addition,suggestions were put forward for the rational use of land in each region.

Conducting a third-party assessment on targeted poverty alleviation can effectively avoid the disadvantage that local government plays as both athlete( i. e. performer of poverty alleviation work) and referee( i. e. referee for poverty alleviation effect) in poverty alleviation to ensure the truth of poverty alleviation,and therefore,it is an important part of the work to win the battle against poverty. Since 2016,the thirdparty assessment teams from colleges and universities for targeted poverty alleviation have achieved good results and performance in the assessment on both the effectiveness of targeted poverty alleviation work and the exit of poor counties in China,and they have made due contributions to the cause of poverty alleviation. However,as a new thing,third-party assessment obviously has some problems,mainly including the following: subjective understanding on the long-term nature of rural poverty alleviation is insufficient,and there is a lack of long-term considerations and related mechanism for third-party assessment; affected by policies and institutions,most of the existing third-party assessment teams from colleges and universities have not regarded third-party assessment of targeted poverty alleviation as a cause,and they lack the motivation to actively study the assessment business; and the third-party assessment staff from colleges and universities for targeted poverty alleviation have low stability and high mobility,not conducive to the long-term construction of assessment teams. In order to establish long-term poverty alleviation and prevention mechanisms,these issues must be addressed squarely and relevant countermeasures need to be taken actively to effectively build a long-term mechanism for building third-party assessment teams from colleges and universities for targeted poverty alleviation.

This experiment was carried out to study the possibility of producing germinating seeds of bitter gourd( Momordica charamtia L.)in the climatic conditions of Europe. Seeds of Indian cultivar‘Nana'were sown in the greenhouse and produced transplants were planted on the field. The plants were cultivated in the field in 2 ways: tied to the sticks or creeping on the ground. During the vegetation,the ripen fruits with seeds were collected 6 times,and after extracting,they were germinated in the laboratory following the routine ISTA rules. The best transplants of bitter gourd were received within one month from the seeds emerging 51. 8%. The transplant of bitter gourd had average height of7 cm,3-4 leaves,out of which the biggest had the width of 5 cm. Such transplants would grow into fruiting plants. When growing bitter gourd for seeds,the earliest fruits were harvested from the plants tied to the sticks. Moreover,the best seeds were harvested from 2/3 of early fruits.For the purpose of seed production,it is recommended to keep only 3-4 fruits per plant and remove other fruits. The produced seeds germinated from 8% to 24%. If the plants were tied to the sticks,their fruits ripened earlier. The used production way and time of harvest of fruits had no effect on the seed germination. The cultivation methods of bitter gourd plants had no effect on the chemical components of fruits.
