major actions to avoid breaking: ‘chosen anti
. fruit breaking varieties, which is an essential step to resolve splitting; a from late July, as soon as every 15 days spray 3g/kg calcium chloride solution once until the
. harvest, or 8 months late, in the fruit surface area spray 50 to 100 times lime
. service; b very early August to early September
.
watering when drought, dirt wetness progressively continued to be at 12% to 14%, can
. through cover movie, straw or straw crown to decrease water dissipation, and also
. prompt drainage to stop waterlogging, make the soil water-containing
. remained secure, can greatly lower the splitting price; c very easy breaking varieties can be timely harvesting and handling in
. mature duration in order to stay clear of fracturing losses.After
.
the jujube start coloring usually occurs immature fruit drop sensation, recognized as . preharvest fruit drop. To avoid this phenomenon can be splashed naphthalene . acetic acid. Use method is in 10 to 15 days of late mature and before mature . splashing 50 to 70 mg/kg concentrations of naphthalene acetic acid or pimacol service one time. When splashing, it calls for fruit . surface, track packed with medications, delaying stalk abscission cell disintegration . time, make the fruit gets to maturity and afterwards typical harvest. After spraying naphthalene . acetic acid, there are no damaging effects on fruit high quality. Naphthalene acetic . acid can not straight soluble in water, prior to using, you need to use a tiny of . alcohol or boiling water to totally dissolved naphthalene acetic acid, then . diluted with water to the use focus. For instance, 5g naphthalene acetic acid plus 50ml of 95% . ethanol, drinking to dissolve totally, after that poured into 100 kg water, mix well that was 5mg/kg . concentrations of naphthalene acetic acid solution. Naphthaalene acetic acid . liquified with alcohol can be kept, when spraying, directly take a certain . amount of naphthalene acetic acid mother liquor thinned down with water. Dissolved naphthalene . acetic acid with alkali option, initially placed the naphthalene acetic acid right into . beaker, add a little water and also heated up to the boil, then slowly include a tiny . amount food base, as well as continue mixing up until totally liquified naphthalene . acetic acid, quit home heating, after cooling down can be watered down with water. Include alkali . have to not place right into boiling water at as soon as, to prevent a great deal of carbon . dioxide bubbles launched, the fluid overflow beaker. Pimacol can be directly dissolved . in water and salt, much more convenient than naphthalene acetic acid. Naphthalene . acetic acid as well as pimacol can be combined with neutral pesticide and also urea, yet can not . be used with alkaline pesticides, such as Bordeaux.In .
enhancement, it can utilize the spray PCPA. Apply 10 to 20 mg/kg focus of . PCPA (ie chlorinated acetic acid) for stopping preharvest jujube fruit decline likewise . have a good result, spraying time is the very same as naphthalene acetic acid.Finally
.
ripening harvest, after spraying naphthalene acetic acid and also various other plant development regulatory authorities, the jujube harvest would certainly be suitably delay, track with sticks,
. raised harvesting challenging. If it takes place, can properly delay the
.
