Abstract

A shoot-controlling agent of an orange can prevent shoots of the variety of oranges from growing without the limitation of time. The shoot-controlling agent can be used before the budding of the shoot or after the budding of the teeth shoot and a sprout being 1cm, so that the shoot can be kept in the state of dormancy for about 70 days, thereby inversing the physiological drop, so as to ensure nutrient content can be supplied to young fruits, thereby improving percentage of fruit setting on a large scale, completely changing the an original method of picking up shoots manually, and laying the foundation for the high yield of the variety of oranges, such as sugar oranges, tribute oranges, and the like.

Description

Agent for controlling tip of branch of citrus

Technical field:

Present technique belongs to agriculture field; In the citrus variety industry, the invention of agent for controlling tip of branch can be controlled the growth of the tooth tip effectively, what break traditions manually plucks the technology of sending, reduce the to bear fruit nutrient consumption of female branch changes the nature physiological fallen fruit, thereby the output of citrus varieties such as granulated sugar tangerine, tribute mandarin orange is increased substantially.

In kinds such as granulated sugar tangerine, tribute mandarin oranges, after the spring first time, the tip was aging, growth rhythm goes out the tip certainly once more, manually pluck the tip as untimely employing, the growth of giving free rein to can consume a large amount of nutritions, if branch length reaches more than the 7cm, granulated sugar tangerine fruit bearing rate is only had an appointment about 1 one-tenth, about about 3 one-tenth of tribute tangerine kind.Several years ago, see county's implant mass citrus variety, but production management process is very traditional, all please with manually plucking tip method, the scene sea of people, the time ends to mid-August from the Gregorian calendar mid-April, the continuous operation several months is to making the orchard worker lose a large amount of financial resources, labour.

For exploring the controlling tip of branch of citrus technology, several years ago, have a mind to plant kind numbers such as granulated sugar tangerine, tribute mandarin orange and pick up strain, the research and development that are used to fill a prescription, fruit tree is divided into groups, strive for the variation test, first-selected with product testings such as ethrel, paclobutrazols, the ratio of by specification is used, test through the time, the former causes young fruit to drop in a large number, remains little, and the latter does not have inhibitory action fully to the growth of the tooth tip, only be applicable to citrus kind in addition, the result is greatly disappointed, Nan Gua still adopt the original tip method of manually plucking so far, reverse its growth, hopes fruit expire the end of the branch on foot.

The purpose of invention:

Because citrus variety belongs to a class of faster growing, so the branch growth is vigorous especially, shoot growth constantly circulates, physiological fallen fruit is obvious especially, employing is manually plucked daily being difficult to of the tip and should be born, the sweltering heat in summer, work as do-nothing operation, participate in wherein, generally sigh helpless, for seeking a kind of new way, think hard to look for and think, repeatedly practise, the improvement improvement again of will filling a prescription, the purpose of invention: finally can reach and to preserve young fruit, can reach the double standards of the control tooth tip again, thereby significantly reduce the labour, power makes its kind reach the limit of bearing fruit.

Prescription:

375 milliliters in glyphosate 10% effective ingredient aqua

2.4-D85% effective ingredient pulvis 1 gram

12.5 milliliters in butachlor 50% effective ingredient aqua

Manufacturing process:

Get 375 milliliters in the aqua of glyphosate effective ingredient 10%, standby.

After getting 2.4-D85% effective ingredient pulvis 1 gram and converting 11.5 milliliters in water and dissolve, standby.

Get 12.5 milliliters in butachlor 50% effective ingredient aqua, standby.

Above three kinds of raw materials are poured into respectively in the container, mixed mixedly, make finished product by specific weight packing.

Using method:

Get 400 milliliters of agent for controlling tip of branch, convert 125 kilograms in clear water, dilute mix mixed, in that the spring tip is aging then, the tooth tip is sprouted preceding or use before the 1cm back of sprouting, fully spraying the outer shroud caulody with sprayer is advisable to dripping, dry weather or use when sunlight is arranged reaches the optimum efficiency value, and the control shoot time is about 70 days.

Compared with prior art:

At present, the preparation that can effectively suppress the Citrus tooth tip, present stage has a kind of citrus that is called to kill tip agent, by the production preliminary examination of academy of agricultural sciences, Guangdong Province, is applicable to when branch length is 1 to 4cm and uses, spray back a couple of days branch begins to dry up, kill tip agent for disposable, by the time about 15 days, when branch grows into Len req, reuse again for several times, put the tip mid-August to the Gregorian calendar, often, take effect fast during use, the efficacy of a drug is strong excessively, touch the fruit of snack made with traditional Chinese medicines and spend skin, continuous tip point has phenomenons such as withered, shedding, unfavorable factor, real difficult large tracts of land popularization on the yield-increasing technology of Citrus.

And the Citrus agent for controlling tip of branch of my invention, can suppress the growth of the tooth tip effectively, be not subjected to the restriction of time, can sprout preceding or sprout at the tooth tip and use before afterwards length is 1cm, the inhibition time is about 70 days, and with the tooth tip Growth Control original state before use of fruit tree, make it be in resting state, because nutrition obtains preserving, volume increase played establish qualitatively the basis, after the use, through relatively, normal fully to physiologic factors such as original Lao Ye, old branch, fruit color of the leather, young fruit period growths, as reach before controlling tooth, to grow behind tooth optimum effect.

Realize the best way of invention:

For realizing invention, through the very long years of several years, the drop accumulation is for obtaining the region of cultivation accurately, data such as weather, it is on probation that branch is freely given the orchard worker, with feedback information, the refinement attitude is bad, makes its prescription finally can reach use and wants safety, the control shoot time will be grown, and realization can thoroughly change the best way of manually plucking the tip.

Claims

1, a kind of agent for controlling tip of branch of citrus, can suppress the growth of the tooth tip effectively, be not subjected to the restriction of time, can after sprouting preceding or sprout, use before the 1cm at the tooth tip, the inhibition time is about 70 days, and with the Growth Control original state before use of fruit tree, makes it be in resting state, because nutrition obtains preserving, volume increase played establish basis qualitatively.It is characterized in that making: 375 milliliters in glyphosate 10% effective ingredient aqua by following materials of weight proportions, 2.4-D85% effective ingredient pulvis 1 gram, 12.5 milliliters in butachlor 50% effective ingredient aqua is formulated, 2.4-D pulvis is wherein converted clear water and is dissolved for 11.5 milliliters, pour into above three kinds of raw materials in the container respectively again, mix mixedly, make finished product by specific weight packing.
