Abstract

Fruit growers are much concerned about problems that the mature period of loquats are advances greatly, and the quality is improved. The present invention provides a method which makes the loquats flowered in advance, the mature period advanced greatly and the quality of fruits improved by partially digging and cutting a trunk of a loquat tree.

Description

Premature method for loquat

One, technical field

The present invention relates to the planting loquat technology, particularly relate to a kind of by digging of loquat trunk cut, thereby reach the method for loquat premature ripening and high yield.

Two, background technology

Loquat is ripe fruit morning that the output time is only second to cherry in a year, and so features good taste, individual big in addition is very popular.Therefore, the orchard worker wishes that loquat is ripe as early as possible, listing.Present known way has only by the seed selection early-maturing variety and realizes, but because the seed selection of early-maturing variety is the work that technical difficulty is very big, and the cycle is long, and general technical staff is difficult to grasp.

Three, summary of the invention

The objective of the invention is to provide a kind of and both can reach the premature ripening phase significantly, realize the method for high yield simultaneously again by loquat being done one simple " dig and cut art " to society.

The object of the present invention is achieved like this: at the loquat of precocity or medium variety, in the January of finishing after gathering, the loquat trunk is implemented to dig a section art, its concrete operations are as follows: choose wantonly a bit below the loquat trunk first branching point, on this homonymy, the following parallel saw kerf of twice of laterally sawing respectively, two saw kerf spacings are 5mm, the degree of depth is 1/3 of a saw kerf place trunk diameter, remove skin between two saw kerfs and wooden with chisel and hammer, in the cutter mouth, clog charcoal mud then, get the ceramic tile of a 15cm * 15cm * 0.5cm again, it is aimed at trunk cutter mouth on one side, strike its opposite side with wooden mallet, deeply cut a hole mouthful and with till the horizontal base of cutter mouthful contacts up to ceramic tile, then use the coir rope bolt on the trunk at tree crown middle part, the other end of rope connects a stake, stake is squeezed into the ground of a cutter mouthful side, make rope and trunk angle at 45, change once rope later on every year, when treating that trunk diameter reaches 15cm, remove former ceramic tile, change into the ceramic tile of 30cm * 20cm * 0.8cm specification, simultaneously trunk two saw kerf spacings then expand and are 0.8cm, surpass the big tree of 15cm for trunk diameter, then directly select the ceramic tile of big specification for use, and determine two saw kerf spacings with ceramic tile thickness.

The weight ratio of charcoal mud preparation is: charcoal powder: clay: water=100: 30: 40, compound method is: earlier clay is pulverized, with water furnishing mud, add granularity again and stir less than 180 purpose charcoal powders after 60 mesh sieves filter.

Can receive following remarkable result owing to adopt such scheme:

1, at present known by " operation " promotion fruit tree percentage of fertile fruit, improve output, the method of improving quality all is confined to the band girdle to branch skin zone basically, still do not have by " operation " and make the precedent that the fruit tree maturing stage shifts to an earlier date, those skilled in the art is not recognized as yet and is repaid examination and remove part bark and the interior potential of wooden deexcitation tree body simultaneously, practice shows, the present invention can make the flowering time of loquat shift to an earlier date 7～10 days, 12～15 days ahead of time fructescence, this early-maturing variety compared with seed selection has shifted to an earlier date major step again, yet for reaching such effect only by shirtsleeve operation very and need not investment.

2, because the nutrition of loquat tree crown manufacturing when satisfying self needs, will transport to root by under the bark, and water and other nutrient that root absorbs also is when satisfying the root needs, will be by transporting to tree crown on the xylem.By common thinking, trunk wooden is removed a breach, is considered to a kind of destructive damage certainly, and it is defeated to influence going up of moisture and nutrition in the tree body, causes the withered of part tree crown, thereby weakens tree vigo(u)r, reduces output.In fact, the result is just in time opposite with people's the imagination, after such operation, the withered of any branches and leaves do not appear in tree crown, even there is not any of short duration wilting, and whole tree crown more shows flourishingly than originally, and maturing stage that the more important thing is loquat in advance, percentage of fertile fruit, single fruit weight and pol all obviously increase.This analyzes theoretically, owing to removed the bark of trunk horizontal 1/3 in the operation, the following defeated channel part of the nutrition of tree crown manufacturing is obstructed, the tree crown trophic level is improved, must help the accumulation of tree crown nutrition, thereby to the differentiation of bud, improve percentage of fertile fruit and improve fruit quality and play positive effect; Owing to removed the wooden of trunk horizontal 1/3 simultaneously in the operation, the moisture that root absorbs and the defeated channel part of going up of nutrition are obstructed, from and improved the trophic level of root, must help the growth of living, promote root of root.Though this particular procedure partly is obstructed the upper and lower transfer passage of loquat, but do not reduce the required nutrition of upper and lower two parts, the barrage of this limited height in the river course, though it can make current be obstructed, improved the water level of upstream, but, be to keep crossing in following unit interval of situation of upstream high water level the water yield of barrage but the flow unlike original is few through result final after the blink because the height on dam is limited.And the present invention is simultaneously after bark and xylem are provided with two such " barrages ", because the trophic level of root improves than original, thereby its absorption function must strengthen, the corresponding increase of failing on it of nutrient, equally, tree crown is under the situation of high-plane of nutrition, its photosynthetic efficient is higher, adding nutrient defeated on the root was improved largely than originally, under this dual favorable factor effect, the nutrition of transporting to root under the tree crown also must increase considerably, this makes root obtain dual favorable factor again, root promotes significantly conversely and goes up defeated nutrition ... this eucyclic direct effect is that the nutrition flow of crossing twice " barrage " in the tree body does not only reduce, also inevitable increase without end significantly.From another angle analysis,, thereby impel loquat to enter the full bearing period in advance because the two combination must force bark, wooden its side direction of strengthening respectively to circulate, and has excited the potential in the tree body.

3, because the present invention is based upon on the basis of transferring the inherent potential of loquat,, and operates simpler and saved the investment and the man-hour of implementing these measures so the effect that its produces is remarkable more than strengthening the effect that water, fertilizer and other control measures produce.

4, because the maturing stage of loquat shifts to an earlier date significantly, quality improving will inevitably improve the commodity value of loquat, thereby has improved orchard worker's economic well-being of workers and staff.

Claims (2)

1, a kind of premature method for loquat, it is characterized in that: at the loquat of precocity or medium variety, in the January of finishing after gathering, the loquat trunk is implemented to dig a section art, its concrete operations are as follows: choose wantonly a bit below the loquat trunk first branching point, on this homonymy, the following parallel saw kerf of twice of laterally sawing respectively, two saw kerf spacings are 5mm, the degree of depth is 1/3 of a saw kerf place trunk diameter, remove skin between two saw kerfs and wooden with chisel and hammer, in the cutter mouth, clog charcoal mud then, get the ceramic tile of a 15cm * 15cm * 0.5cm again, it is aimed at trunk cutter mouth on one side, strike its opposite side with wooden mallet, deeply cut a hole mouthful and with till the horizontal base of cutter mouthful contacts up to ceramic tile, then use the coir rope bolt on the trunk at tree crown middle part, the other end of rope connects a stake, stake is squeezed into the ground of a cutter mouthful side, make rope and trunk angle at 45, change once rope later on every year, when treating that trunk diameter reaches 15cm, remove former ceramic tile, change into the ceramic tile of 30cm * 20cm * 0.8cm specification, trunk two saw kerf spacings are then got to expand and are 8mm simultaneously, for the big tree of trunk diameter, then directly select the ceramic tile of 30cm * 20cm * 0.8cm specification for use, and two saw kerf spacings are got 0.8cm by ceramic tile thickness above 15cm.
