The time of fertilization and fertilization can be carried out after the drought has ended. Generally, organic fertilizers can be used. For example, bar fertilizer, compost, garbage, and weeds, etc. Fertilizer 25 kilograms, to achieve "pounds and nuts," 2 kg of available nitrogen fertilizer, or 1.5 to 2 kg of special compound fertilizer for kiwifruit. Fertilization method: Dig two deep grooves more than 35 centimeters around the tree plate or on the opposite sides of the tree canopy. The direction of the ditch can be one year from east to west and one year from south to north. The bottom layer of the ditch is filled with crude organic fertilizer. Grass, etc., fill in the middle layer of organic fertilizer, such as bar fertilizer, etc., the top layer can be quickly applied nitrogen fertilizer, such as urea. However, in the absence of drought relief, the rain did not penetrate under the circumstances, do not use ground fertilization, so as not to damage the root body. Trimming winter has a large amount of pruning. Care should be taken to keep the number of buds and trim length and manner. The pruning time was two weeks after the fall to the first two weeks after the injury. During pruning, the dead branches, branches and branches, thin and weak branches, cross branches, and dense branches were cut off from the base. The results were from 2 to 3 years old and the result sites were outside. The results of the transfer of the mother branch, to be updated in time, cut off from the base; the main stem, the main branch of the chaotic plants, to manage the rationale of the main stem, the main branch of the affiliation, and then according to the characteristics of the species to trim. As early as the Chinese species, Jinfeng and other species, due to short internodes, the results of strong, should use heavy pruning. Leave 4 to 6 short shoots for short and weak vegetative branches; 6 to 8 short shoots for moderately robust vegetative shoots; result in 6-8 short shoots at the result site, usually 25 to 40 per plant. Result mother branch. Delicious species, such as Xu Xiang, Bruner and other species should be lightly cut, using the long-tip pruning method, leaving 6 to 10 short stubs for short and weak nutritional branches, and 11 to 16 short stubs for moderately robust nutritional branches; As a result, 6-8 buds were left short at the result site, leaving 20 to 30 mother trees per plant. After trimming, the branches should be left flat and tied with a piece of cloth on the surface so that the resulting mother branches can be evenly distributed. The scaffolding is the basis for high-quality and high-yielding kiwifruit. In the unplanted fields, the branches should be clearly distributed after pruning, and the time for easy binding should be grasped. The original damaged or damaged fields must be repaired or replaced in time. Deep turning to improve soil through deep turning can loosen the soil and enhance the permeability of water and fertilizer. The deep-turning time is generally from the beginning of November to the beginning of December, and can also be combined with fertilization during the deep-turning process. The depth of deep-dip is required to reach about 40-50 cm. However, care should be taken to cut as little as 0.5 cm above the root. Clearance of garden land is mainly to eliminate weeds, clear ravines, prevent diseases and pests, etc. The garden cleaning can be combined with winter pruning. The pests and branches cut off must be burned or buried deeply. The pesticides used to prevent diseases and pests can be formulated as 60 times liquid crystal lime sulfur. The request is completed before sprouting. Http://Content/968e57c7-5296-47bb-b9fc-1af7818dfff3?cType=2 Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.

In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
Kiwifruit management points in winter
Water Management The roots of kiwifruit belong to the fleshy roots and are sensitive to the requirements of soil moisture. The requirements for water are: hi humid, fear of drought and fear of waterlogging. According to precipitation, it is required that the gutters and gutters in the orchard must be unobstructed and reach the rain through the garden.
