Does severe winter have what to work alive in walnut garden? Irrigate the water that seal aspic, win

One, irrigate delay of Mo Chi of the water that seal aspic

Walnut garden year the water requirement inside cycle is not big, but irrigate the water that seal aspic very be necessary, not only want to irrigate, and irrigate aptly fully.

Dry tip phenomenon can appear after nuclear peach live through the winter, early days show is not quite apparent, what the meeting when sprouting exposes is as clear as day, common people says is to freeze to death, a general designation on the book is sprout phenomenon. This kind of phenomenon, each district exists generally, happen from time to tome year after year, young tree is heavier, large tree is smaller. This is be caused by of the dehydrate inside tree body, place of freeze injury of and rather than fights freezing ability for nuclear peach is 28 ℃ 0, exceeded this limit to just can appear freeze injury, in this limits less than, nuclear peach live through the winter is safe. The main reason that spring discovers Gan Sao has at 2 o'clock: It is xylem serious dehydrate, coldest days, in those days taper of new student branch can have frozen appearance, but if the moisture inside branch is enough, the meeting after freezing protects cellular wall naturally, once,be like fruit branch dehydration, did not protect put oneself in another's position, meet wall of direct frostbite cell or freeze to death cell. 2 it is to grow later period applies nitrogen to had been measured big, if underground is pure,apply urea, or fertilizer of a large number of devoted night soil, quick result, the Qiu Wan after can creating branch end stops long, in-house organization is not contented, fight a gender to lose, cause freeze injury easily.

Written guarantee in the evening Bao Bing, by day namely defrost, it is the gold period that irrigates the water that seal aspic. Irrigate early, the meeting because air temperature on the high side, moisture capacity is large, go against the live through the winter that defend water; Irrigate evening, because frozen earth layer is deepened,meet again, moisture is hard to issue ooze, go against soil store water. Accordingly, did not irrigate the walnut garden of the water that seal aspic, should have only irrigate condition, at once the action rises now. Water of the Qiu Yu after this year is more, other orchard need not water, but walnut garden seals aspic water to must be irrigated, the young tree that gives birth to less than 4 years more should such.

2, winter Qing Dynasty wants field complete

It is very important that walnut winter Qing Dynasty works field, can reduce cardinal number of ill bug live through the winter greatly, disease of shading of effective control the coming year, brown corrupt disease, anthrax disease and the hair opportunity of survival of all sorts of insect pest are led, nip in the bud. Clear garden work includes:

(1) clear deadwood, clean deciduous leaf, collect deadlocked fruit to wait, burn down is centered outside garden or bury greatly;

(2) blow become warped except old tree skin, reduce place of pest live through the winter;

(3) curium the daub on the mouth cicatrizations agent, do to big cut in order to protect, the young tree inside 3 years, crown of a tree is operated lowly, easily, best can will cut a mouth to also use heal agent seal, cut a Gan Sao in order to reduce;

(4) after above handicraft work finishs, gush kills bug antiseptic, the mark that use a heavenly body 4000 doubly 3721 1000 times fluid, complete garden fine spray, crown of a tree wants gush completely wet, ill bug is striven for sweep light.

3, cankered disease prevents and cure should seasonable

The decay in walnut garden is ill, endanger degree absolutely no less than other trees kind, want to affect only, tree situation is met rapid and abate, light person dead branch, the person that weigh is cultivated to death, transmission sex is splitting, invade catch rate is extremely high. Newest research indicates learned man of ill authority of national fruiter decay, below natural condition, cankered bacteria anniversary can arise, occurrence fastigium of new unripe ill spot is November ～ March, the happening according to cankered disease the rule, in cent unripe spore transmits occurrence height of ill spot of height, new student, ill spot to expand the crucial period of the height prevents and cure the most effective. Accordingly, decay of prevention and cure of winter walnut garden is ill not only seasonable, and very be necessary. Complete garden chases individual plant to be looked carefully at carefully when prevention and cure, if discover cankered disease spot uses a knife,will ill spot is blown clean, with affected part of daub of mark of 50 times star.
