The invention provides a pear tree two-arm direct-motion type shed frame tree shape which comprises a tree trunk. The tree trunk has two boughs which grow in a direct-motion mode, and base angles of the two boughs are 45 degrees. When reaching a frame-climbing point, the boughs are fixed on a horizontal shed frame in a direct-motion mode, and extended long branches of the boughs are guided onto an elevation guide line in a perpendicular mode. The boughs have long placed fruit branches which are arranged in parallel and vertically extend into intervals. Before the two boughs climb a frame, two horizontal robust side position branches which are pulled along the reverse direction to be parallel to the boughs after the horizontal robust side position branches grow upward to the frame face. The side position branches have F-shaped single-shaft long placed type fruit branches which are arranged in parallel and vertically extend to the intervals. The tree shape only has the two boughs, and therefore the problems that an inclined crown appears easily in a three-bough tree shape and the main boughs intersect are solved. The two boughs oppositely extend in a direct-motion mode and do not influence each other. The two-bough tree shape is easy to reshape, and the two boughs are easy to form after the trunk is fixed. The phenomenon of lack of branches appears in a three-bough shed frame due to the fact that sprout force of a pear tree is weak. The three shape has the advantages that cultivation density is high, early-stage output is high, light conditions are good, the branches are easy to arrange in an ordered mode, uniformity of fruit quality is high, and standardization is easy to achieve.

The invention discloses a microorganism grouting method capable of improving an early-stage calcium carbonate deposit volume, which comprises the following steps: (1) a nutritive salt solution is added into a microorganism bacterium liquid to obtain a mixed liquid of bacterium liquid and nutritive salt, and standing is carried out for 0.5-1h; and (2) during grouting, the mixed liquid of bacterium liquid and nutritive salt is blended with a calcium salt solution according to a predetermined proportion. Due to the adoption of a microorganism grouting material, not only is the total output of calcium carbonate sediment effectively improved, but also the early-stage output of the sediment is can be effectively improved, so that important significance is provided for blocking concrete cracks by utilizing a grouting method. Only a lot of calcium carbonate sediment is generated in relatively short time, the concrete cracks can be blocked in relatively short time, and thus grouting amount and times can be reduced.

The invention relates to a peach tree pruning method which belongs to the technical field of peach tree cultivation. After peach seedlings are colonized, 15cm to 20cm of fixed pole height is adopted; a fixed pole is provided with more than 5 to 7 good leaf buds which grow straightly upwards along a young sprout cultivating central pole on the top end; other germinal young sprouts at the matrix form wheel-shaped branches; after 3 to 4 years, 3 to 4 of the branches are selected as boughs to be cultivated; both sides of each bough are evenly provided with side branches and bearing branches; the angles formed between the boughs and the ground are kept to be about 30 degrees to 40 degrees. After 4 to 5 years of cultivation, a coiled tree shape with the 3-to-4-year boughs as the backbone is formed. The tree shape cultivated through the method makes full use of the characteristics of the natural growth of a peach tree; in the preliminary period, tree crown expands quickly, has high yield and good quality, is low in height, convenient and labor saving in operation; the light condition in the bore is fully improved, the matrix is not bald, the full bearing period is prolonged, the tree is strong, the economic life is long, and the peach tree cultivation has very good promotion and application value.

The invention provides a fast frame-climbing method of shed frame pear tree boughs. The frame-climbing method is carried out on a shed frame of a three-line one plane or two-line one plane mode, and frame climbing is carried out by three steps of strengthening, pulling in an inclined mode, and pulling in a level mode. The first step of strengthening is that young shoots are guided onto an elevation guide line in a vertical mode during a growing season so that the young shoots can keep a vertical growing state. The second step of pulling in an inclined mode is that base parts of the shoots growing vertically are pulled in a level mode and fixed behind the shed frame face during autumn of the same year, and then are guided onto the elevation guide line according to a 45-degree angle, namely, the base parts of the shoots are firstly pulled in a level mode and fixed and then pulled in an inclined mode. The third step of pulling in a level mode is that the shoots are pulled in a level mode and fixed on the shed frame face during autumn of the next year. The fast frame-climbing method has the advantages of being fast in frame-climbing, few in water shoots, small in trimming quantity, large in frame face fruit area, high in output and the like.
