In front we were told yuan forest, green Lin Helu is sweet the characteristic of peach of 3 kinds of nucleuses, next we will say to be in for everybody in cultivating a process, peach of these 3 kinds of nucleuses can appear easily what plant diseases and insect pests, how do we prevent the happening of this kind of plant diseases and insect pests in daily administrative lieutenant general.
To yuan it is OK that Lin Helu sweet walnut grows year after year when the result, we are about to begin more exuberant to growing branch to undertake opening business vimineous angle, the branch that the end that such doing can let grow already can get even sunshine, promote grow add branch bear degree, OK still and effective addition more bud, the crop that plants walnut is mentioned highest.
When having vimineous point of view, we can be commonly below the tree, along the predestined relationship outside crown of a tree, secure good stub first, reoccupy grows club join to become a square, the length of club chooses 6 meters or so normally, secure directly with cord next go up in stub, another is secured go up in the tip of a tree, be down branch closely drawing, so that ventilated and pervious to light, additionally the branch of knot full walnut is met by press a turn naturally, at this moment we are about to use a club erect rise, open branch, lest press,break branch. Bearing in what make good nucleus peach tree after measure, we still need to cultivate walnut the deadwood above to cut off, additionally flagging branch wants as far as possible time shrink, we should tell the share that grows to also be cut off, choose the branch with better the way corp is growing leaving a department.
The requirement that these 3 kinds of walnut uphold pair of fertilizer is exceedingly simple, be in annual July the hard nucleus of walnut of the last ten-day of a month period, we are about to notice fertilization, the fireweed inside the orchard should keep clear of first before fertilization, it is next all round nuclear peach the canaliculus that gouge opens type, assure to there is 6-8 all round peach of nucleus of every individual plant usually, the deepness control of channel is in 10-20cm, the scale of good NPK must be controlled when choosing fertilizer, we suggest the scale of NPK is 14: 4: 7, it is OK that the dose of every nucleus peach is controlled in 0.2-1.5 kilogram. In after applying good fertilizer, still need to mix on clay is enclothed, such our primary fertilization jobs were finished.
Be in after entering autumn, we apply organic fertilizer to nuclear peach as far as possible, main in order to ferment the earthy miscellaneous fertilizer such as good gallinaceous dung is given priority to. When applying organic fertilizer again, must when after its had fermented completely, just can use, the root that can burned-out walnut establishs the organic fertilizer that did not ferment good otherwise, the corrupt mellow soil that when fertilization each large nucleus peach tree wants to use 50 kilogram is miscellaneous fat, after scattering fertilization to expect, same need mixes on undertake enclothing after earth. We are in finally after applying fertilizer, can irrigate on right amount water, we combine the dosage of water the humidity of the rainfall at that time and edaphic itself, irrigate on a few water appropriately.
If the nutrient supply to nuclear peach is insufficient, cause nuclear peach easily to grow slow, cultivate situation slacken, if encounter microtherm weather, still can cause freeze injury easily, the photograph of plant diseases and insect pests of walnut relatively the tree of other is planted the meeting is a few less. Yuan forest, green Lin Helu is sweet the disease-resistant capability of peach of these 3 kinds of nucleuses is stronger, but ill to walnut anthrax, we or need take precaution seriously, appear easily otherwise premature drop, cause reduction in production. We can be after May, every other time of 15 days, be about to undertake medicaments sprays, sprayed medicaments can choose much bacterium spirit. When using much bacterium spirit, we matched our the medicaments solution of 800 times to be able to be used. At the same time we have observation to walnut everyday even, see must be excised in time when ill fruit, still have dropping walnut, want seasonable belt to give an orchard, undertake destroy by melting or burning.
Inside nuclear peach insect pest, the harm with scarab is the greatest, and very general. Scarab hides in soil by day, climb a tree in the evening, eat the lamina of the lamina of nuclear peach stealthily, form many a small hole, affect what walnut cultivates to grow. Still having is red spider, red spider can create the lamina of nuclear peach maize spot, add gradually become repeatedly more, cause walnut to cultivate Xie Fahuang atrophy to fall off finally finally, in red spider of prevention and cure when, what we can choose chroma to be every to rise 25 grams is efficient ester of chrysanthemum of chloric fluorine cyanogen, allocate its for the medicaments solution of 1500 times, undertake spraying to nuclear peach whole.
Good, arrived to say good-bye with everybody again today when, in if you are in what walnut cultivates,be being cultivated, appeared a few doubt, you can leave a message beneath, we can be in next in content, explain to everybody.
