Background technology

Banana tree (Musa nana Lour.) originates in the southeast, Asia, is the large-scale herbaceous plant of Musaceae Musa, in the tropical and subtropical zone area, cultivating and growing is widely arranged.Banana is the fruit of world's fresh fruit volume of trade maximum, and its flavor is fragrant and sweet good to eat; Fruit contains abundant nutriment and multivitamin and mineral matter, is large one of fruit of eating raw that people like.The banana stem is comprised of terrestrial stem and subterranean stem, and terrestrial stem is that false stem is formed by the leaf sheath parcel, and it is subterranean stem that false the lower portion of the stem forms bulb, and every leaf sheath base all has a resting bud can form the suction bud.Banana is inhaled the pumping of bud from the annual Spring Equinox, and maximum with the 4-7 month, the suction bud number of individual plant germinating can reach at most 8-15.Inhale between bud and maternal plant soil nutrient, moisture, illumination and growing space are existed to keen competition.If not inhibitory control inhale bud growth, let alone pumping and grow, can consume the growing way of a large amount of nutrients of female stem, the female stem of weakening, make its delay of blossoming and bearing fruit, cause maternal plant fruit yield and quality decrease.In addition, the growth that a large amount of bananas are inhaled bud can reduce the ventilation and penetrating light degree of Jiao Yuan, and air humidity is raise, and contributes to the Epidemics of damage by disease and insect.At present, inhaling bud for banana in production is to take the method for manually rooting out by strain to control its growth, artificial except the bud effort is time-consuming, the work work efficiency is low, easily injure maternal plant and affect its growth in rooting out the process of inhaling bud, if inhaling the bulb of bud is not rooted out fully, also pumping again, need to again shovel and dig.The artificial method except bud is not suitable for for large-scale intensive banana cultivation.

It is a certain amount of 2 that existing bibliographical information adopts, and 4-D or 2,4-D butyl ester are applied to banana and inhale on the cross section of bud and can play and kill the effect that banana is inhaled bud, but there is serious problem in this technical method, is not suitable for applying.Reason is: because 2,4-D and 2,4-D butyl ester are auxin substances, have very strong interior suction transport properties.2,4-D and 2,4-D butyl ester working concentration have the effect of Promoting plant growth when low; The effect that there is weed killer herbicide when concentration is high, it is applied to after lateral bud to be absorbed and is transported in the banana maternal plant, cause the uneven easily lodging of maternal plant stem stalk growth, if can affect the growing as made the blade yellow or making the fruit distortion of maternal plant when amount ratio is larger, even kill maternal plant when serious.

Summary of the invention

Purpose of design: be intended to overcome the artificial bud and employing 2,4-D or 2,4-D butyl ester of removing and prevent and kill off the long technological deficiency of suction blastogenesis, a kind of technical method of banana suction bud chemical control easy and simple to handle, quick, laborsaving, efficient is provided.

Design:

Adopt the technological means of chemical regulation effectively control the growth of banana suction bud or kill the suction bud, this technical method has growing of maternal plant is had no adverse effects, can improve again the field growing environment, promote the growth of banana maternal plant and blossom and bear fruit, and technical operation is easy, efficient, laborsaving, remove bud effective, can improve the advantages such as banana yield and quality, be that the prevention and control banana is inhaled the long important technology method of blastogenesis.

Technical scheme: a kind of prevention and control banana is inhaled the long technology of blastogenesis, relates to a kind ofly by adopting appropriate chemical substance to be processed, and prevents and kill off the technology that banana is inhaled bud.Carry out according to the following steps: select the date of fine day without rain, with sharp cutter or shovel, surgery together the suction bud, the attention otch will be put down, and with writing brush, the flumetralim liquid medicine painting of 0.5-1.0ml is inhaled to the bud cross section; Or the card punch that is 0.5-1.0cm with aperture is inhaled the bud tissue from inhaling middle part, bud cross section toward pressing down to get, pressing down the degree of depth is 4-6cm, make to inhale the bud middle part and form an aperture that dark 4-6cm, diameter are 0.5-1.0cm, draw the flumetralim liquid with the syringe of 50ml needle-less, toward inhaling in the bud aperture, apply 0.5-1.0ml flumetralim liquid; After perhaps the flumetralim liquid being diluted to one times with clear water, with the syringe of 50ml needle-less, draw the flumetralim dilution, toward inhaling in the bud aperture, apply 0.6-1.0ml.This technology is applicable to the banana of different sizes and inhales bud.

The present invention compares with background technology, and its characteristics have:

The one, utilize the flumetralim with the double action of contace poison of local interior suction to process banana and inhale bud, appropriate flumetralim can effectively be controlled the growth of suction bud or kill the suction bud, and can not have influence on growing of banana maternal plant, control effect arrival 81-97%;

The 2nd, utilize appropriate flumetralim to process banana and inhale bud and can play and improve microclimate between any of several broadleaf plants vegetable garden, promote the banana maternal plant to grow, significantly improve the effect of banana yield and quality;
