Project Implementation,3.1 Water-boxx IntroductionIn 2012-2013Introduced and learned Groasis water-boxx technology and concerned knowledge from foreign experts and internet; In May, 2013 Introduced Groasis water-boxx 300 sets.,Technical material collection and introduction,三. Project Implementation,三. Project Implementation,3.2 Plant species selectionDesert plant species：Picea mongolica, Pinus sylvestris var. Mongolica, Pinus Pinea, Sabina vulgaris, Prunus Mongolica, Populus euphratica, Elaeagnus angustifolia, Hippophae rhamnoides, Haloxylon ammodendron, Caragana korshinskii, Hedysarum scoparium, Calligonum mongolicum, Caragana sinica, Tamarix ramosissima, Ulmus pumila, Ammopiptanthus mongolicus, Atraphaxis bracteata, Nitraria tangutorum, Zygophyllum xanthoxylum.Mountainous tree species:Picea crassifolia, Sabina przewalskii, Picea mongolicaVegetable plant species：eggplant, pepper, tomato. 24 plant species in total joined in the experiments.,三. Project Implementation,三. Project Implementation,3.3 The experiment and demonstration of water-saving afforestation in different landtypes 6 difficult landtypes in Minqin desert and mountainous areas were selected and afforested by Groasis boxx. The difficult landtypes were moving dunes, semi-fixed sandy land, low land among dunes, grain to green land, farmland and mountainous areas, a lot of experiments were done for water saving afforestation, the technology were summarized.,三. Project Implementation,Afforestation in Moving dune area,Afforestation in semi-fixed sandy land area,半固定沙丘,Afforestation in lowland among dunes,Afforestation in Grain to Green land,困难立地条件的选择,Vegetable plantation in farmland,Afforestation in Mountainous slopes,三. Project Implementation,Some afforestation demonstration,三. Project Implementation,Some afforestation extension,Plant surviving ratio(%) in different landtypes afforestation（%）,三. Project Implementation,Through the water-saving afforestation experiments by water-boxx，plant surviving ratio is improved 10-90% in 6 landtypes, average surviving ratio was improved 25% and more，the soil moisture is lower and environment is harsher, plant surviving ratio is more higher. Generally, Plant surviving ratio situation are low land among dunessemi-fixed sandy landmoving dunes areaabandoned landmountainous slope areafarmland than the control(contrast).,三. Project Implementation,3.4 Soil moisture and micro-environment after water-saving afforestation,三. Project Implementation,三. Project Implementation,After Groasis afforestation, the water-boxx itself influences the surroudings micro-environment of the boxx, The plants can be shade, adjust the temperature, reduce wind-sand and wind-erosion, improve the air humidity, improve microorganism envir., avoid weeds growth and wild animal bite and so on. It provides a very good micro-envir. for plant survive and growth.,三. Project Implementation,Wind-erosion effect research after Water-boxx afforestationIt is obvious effect for reducing wind-erosion in the box surroundings,三. Project Implementation,3.5 Plant growth after afforestation,The plant height comparsion between box plant and control,After 3 years Groasis afforestation experiments，most of plants can improve growth 15-40% than the control，the biggest growth can improve 300%. In the first year, the growth of needle trees is not obvious differences, however, broad plants are obvious differences in growth.,三. Project Implementation,3.6 Cooperation and training April, 2012, Mr. pieter and Ms Zhang Suchao visit Gansu Desert Control Research Institute (GDCRI) , We have a good cooperation and information exchange, and applicate the project. 16-18, April, 2013, Mr. Pieter and Ms Zhang Suchao visit GDCRI, 58 participants from Gansu province, China joined the training course on water-boxx technology, a new technology was learned and a good information exchange and cooperation was done with arid-afforestation. May, 2013, Ms Zhang Suchao visited the experiments and supervised the afforestation,三. Project Implementation,Afforestation demonstration,3.7 The project achievementsFinished introduction of Groasis water-boxx technology and Groasis water-boxx 300 sets;2. Finished the technology absorption and using recreation in China.3.Realized water-saving afforestation and demonstration of 24 more plant species at 6 difficult landtypes in Minqin desert and mountainous areas of 6.7hm2, surviving ratio is improved by 40% more，water-saving efficiency is improved by 30-50%and extension4.Publish 4 papers, master the technology, educated 2 Ms. Finished the project objectives,三. Project Implementation,四.Development prospect,The technology can be adopted in difficult landtypes of water shortage arid and semiarid areas, like desert, Gobi, salty land, mountainous and hill land, karst land, abandoned mine and so on. It is suited in the arid and semiarid area afforestation. In the area of precipitation is more than 150mm or ground water table is higher than 6m, after the right plant species selection and afforestation, it can have a good eco-restoration. However, in the extreme arid area, it is deep ground water table and very low precipitation, the soil moisture is too low naturally in the deep soil, afforestation should be carefully. It can be extended extensively in China arid and semi-arid areas.,
