Abstract

The invention discloses a tangerine ring-embedded high-yield cultivation technology. 20th thin iron wires with the length ranging from 12 cm to 16 cm are used for conducting ring embedding on the stem portions at the lower end of a first fruit branch and deeply reaching the phloem in the tangerine early flowering period, and the phenomena that organic matter is conveyed downwards, so that a large amount of nutrient is used for excessive growth of branches and leaves, and a large number of flowers and fruits do not obtain enough nutrient and fall off at the early stage are prevented. Organic nutrient consumption is reduced by ring embedding in cooperation with other measures such as surplus bud removing, pruning and topping, the organic nutrient is conveyed to the fruits, then fruit growth is facilitated, fruit falling off is reduced, the number of ripe tangerines is increased, and therefore the yield of the tangerines is greatly increased.

Description

A kind of tangerine ring embedded high-yield culturing technology

technical field: the present invention relates to a kind of tangerine ring embedded high-yield culturing technology, belong to agriculture tangerine cultivation field.

technical background: tangerine produce in fruit development early stage the problem of coming off be one of current difficult problem of failing fine solution, fruit is not grown expulsion rate and is still had aborning 50% left and right, high reaches 70%, severe inhibition the raising of tangerine output.

Cause that tangerine fruit does not grow that the external factor coming off has that arid, illumination deficiency, sick worm are caused harm, high wind or bloom and meet rain shadow and ring embryo fertilization etc.; The trophic disturbance of trophosome and gonophore is to cause tangerine fruit not grow the internal factor coming off, there is double-dealing type in large this imbalance of Tanaka: one is because soil property is thin, rich water is not enough, cause cotton plants short and small, leaf area is little, and photosynthetic yield is very low.Become the concentrated center of organic nutriment owing to weighing up most existing fruit, the young fruit later occurring can not get enough nutriment and comes off in a large number.Another kind of imbalance is that moisture and nitrogenous fertilizer are too much, nourished and grew prosperous, and branches and leaves generation excessive growth, photosynthetic product consumes on nourishing and growing in a large number, makes flowers and fruits can not get enough nutrients, and plant flowers and fruits in early stage are come off in a large number.

At present, promoting tangerine fruit development, reducing in the research coming off, most of blade face spray reagent method that adopts.Refer to spray the nutriment of drawing for tangerine plant in the time of the tangerine growth regular period, although the method can reach certain effect, excessive increase the tangerine cost of cultivating.

summary of the invention: provide in order to overcome above deficiency, to the invention reside in that a kind of tangerine control is long, fruit retention is real, production-increasing technique.

Tangerine fruit is not grown the main cause that comes off: the one, and inherent physiology nutrient distribution imbalance, the 2nd, extraneous mechanical damage.With interior because foundation, the rule of carrying by available nutrient, ensure that fruit branch has sufficient nutrient, adopt ring embedding method, in conjunction with traditional field management measure, control available nutrient consumes, rest point concentrated young fruit storehouse that transfers to, short young fruit growth and development, increases tangerine number and tangerine size, reduce expulsion rate, thereby make tangerine high yield.Tangerine root system and stem apex absorb nutrient and preponderate, seize available nutrient in order to make tangerine fruit metabolic pool, in seeing the stem position of florescence in the first fruit branch lower end, No. 20 thin wires long with 12-16cm encircle embedding, deeply reach phloem, form gradually warty callus, what restriction organic matter was too much transports root to, and in conjunction with smearing superfluous bud, pinches and pluck the measures such as fruit branch group point, nutrient is concentrated and be transported to tangerine fruit storehouse, ensure that tangerine fruit has sufficient nutrient.

This key problem in technology is following four steps:

1, select ring embedding period: select to nourish and grow and the particularly thorny Sheng flower bud initial bloom stage (first arrival late April in April) of reproductive growth.The selection in ring embedding period is relevant with the growth and development state of tangerine strain, and the tangerine field of over growth must suitably shift to an earlier date in order to prevent excessive growth, and the slightly poor cotton field of growth potential can suitably postpone.2, select ring embedding object: select tangerine strain or the prosperous strain of robust growth, can cross ring embedding and weaken it and nourish and grow, promote the transfer at nutrition center, reach to increase and protect tangerine fruit development and reduce the object coming off, should not encircle embedding for weak strain, diseased plant, in order to avoid caused early ageing a little less than nourishing and growing.3, the method for ring embedding: select apart from ground 30 centimetres of left and right, on the stem of the first fruit branch bottom with long No. 20 thin wires of 12-16cm around stem 1～2 week, tighten and make it embed stem epidermis, deeply reach phloem and form gradually warty callus, what restriction organic matter was too much transports root to, and degree of tightness is suitable.Do not have if cross pine the effect that nutrition production is dammed, controlled in ring embedding; Tension easily operates xylem affects the transport of inorganic nutrients and moisture, even can cause stem to meet the disconnected phenomenon of windbreak.4, the cultivation management after ring embedding: the cultivation management after ring embedding is identical with conventional cultivation technology, but after adopting ring embedding technique, unnecessaryly adjust by mepiquat chlorideization again, after ring embedding, within 20～30 days, should carry out 1 time checks, if find the obvious early ageing of tangerine strain, can unclamp at any time iron wire, to eliminate the impact of ring embedding.

The effect of increasing production obtaining:

1, tangerine adopts ring embedding technique can reduce tangerine fruit not grow and come off, improve setting ratio (especially improving setting ratio in early stage), and synergy fruit development quality, improves output, and has and control or prevent excessive growth, the effect of premature ripening.2, ring embedding law technology is simple, and cost is low, is easy to promote, and effect of increasing production is obvious.3, tangerine ring embedding technique is the application of fruit-tree girdling theory, but its technology is more simple and convenient than band girdle, and encircles embedding and can not cause outer wound to produce gummosis, can avoid infection process wound.Meanwhile, the flexibility of ring embedding technique is larger, and visual plant strain growth situation is separated division ring embedding at any time, forms rapidly perithelium, restore normal growth.

Claims

1. a tangerine ring embedded high-yield culturing technology, is characterized in that: see when colored at tangerine plant the first fruit branch, implement ring embedding technique.

2. a kind of tangerine ring embedded high-yield culturing technology according to claim 1, it is characterized in that: the method for implementing ring embedding is: with long No. 20 thin wires of 12-16cm around stem 1～2 week, tighten and make it embed stem epidermis, deeply reach phloem and form gradually warty callus, what restriction organic matter was too much transports root to, and degree of tightness is suitable.
