Having the management history of san hua li cultivation is very instructive for the farmers. The following is a small compilation of the annual history of san hua li crop management and pest control techniques。
(a) the month of january
Management purposes:
1. Deworming, fungicide, flowering, flowering, if drought occurs, can take root or spray water
Plumbing. Plumbing, aphids, white powder
Management highlights:
(1) a pesticide may not be sprayed with a sulphur formulation during flowering, in case of a fallout。
(2) during the gestational period, 30g of cloud size 120,1 to water 60kg or of a bottle of plant protection 60kg or 920 powder 5g to water 150 to 250kg + potassium phosphate。
(3) extrusion fattening: 50 g of potassium dihydrophosphate may be used to spray against the water 30 kg of desolation fruit。
(4) accompanying fruit in a timely manner, ensuring appropriate density and quantity, regulating the distribution of nutrients, reducing growth and conflict of results, and increasing single and large fruit rates。
Monthal edicts: march (spring - rain) and april (cleaning - rain)
Management purposes:
1. Prevention of pollinosis, acute anthrax, leaf-dollant, prevention or mitigation of the physiogenic fallout, and removal of the vermin。
2. Following the fertilizer of the fruit, promoting the expansion of the fruit, and striking the top as appropriate (with long branches)
Management highlights:
(i) to perform fruit-reducing, conservatory and fruit-bearing tasks at a rate of 1. 5 cm in order to increase the path, increase the weight of single fruit and achieve high yield. Tiny, weak, insect. Attention shall be paid to the rationality and distribution of the positions left behind. It is also necessary to determine the extent of the consequences based on the strength of the branches. The results are weaker and more numerous and can be more fruitless。
(2) during the period when the fruit expands, if the spring rises too fast and thrives, it will result in a conflict of nutrients between the branches and the fruit, which will deprive the fruit of sufficient nutrients, and will result in the cessation of growth or the loss of small and medium fruit. This is a time of short-term control of spring growth。
Control methods are: tops, around 20 cm spring, to remove the point of growth; short stop at 20 cm spring; and multi-utilized 15 g-to-water 15 kg squirt growth when spring rises up to 20 cm。
(3) the period of fruit expansion, such as yellow in leaves, indicates a lack of nutrients in the tree。
Exterior fat pursuit should be carried out, with a general measure of 50 kg water + potassium efficiency tricon nutrient 50g + pioneer 1 pack of spray. Sprayed once every 7d and three times in succession。
March. May
Management purposes:
1. The external pursuit of micro-fertilizers or water soluble fertilizers, dominated by potassium, calcium, to improve the quality of fruit, sweetness, increase, increase, increase weight and multipowder
2. The removal of orange fly, vermin, and protection against coal smoke。
Management highlights:
(1) magnificent fruit during the trivalent period, 30d per 50kg water + polybacterial 30g + high-efficiency potassium tricon trophic fluids 50g + pioneer 1 pack of plasters sprayed on fruit branches once every 7d and two to three times in a row。
(2) be careful to observe the growth of fruit-leaved leaves, such as when they begin to turn yellow, indicating a shortage of fat, and to pursue extra fat and turn the leaves green。
Monthly edicts: june (mong) and july (summer)
Management purposes:
1 the extraction of zhuan lee fruit is recommended for use: da niang + tuflix, and the prevention of needle bees by the use of agreens before the harvest。
2 one week after the fruit is fertilized, the tree position is restored and insecticidal is eliminated。
Management highlights:
(1) increase the weight of single fruit, increase the sweetness of the fruit, and keep the face clean
(2) to promote the separation of buds and reduce the number of years。
May-month edict: august (low autumn - summer), september (white lun - autumn), october (choose - frost)
Management purposes:
Prevention of duct tape, decomposition, folic and edible diseases bug
Management highlights:
(1) reduction of the source base of the disease plasma lime can be used to protect the tree body with white trunks or lime oil。
June: november
Management purposes:
Plum trees in orchards; shearing, fertilizing and treating winter pests。
Management highlights:
(1) the result tree requires that the leaves be fully lost before the winter cold in order to ensure that the branches are fully ploughed, to promote the growth of buds and bellies and to improve the flowers。
(2) a combination of pine fields, before and after winter, digs 25 to 30 cm loops under a canopy drip line, breaks horizontal roots, controls water fattens, promotes the separation of leaves and buds, and in a few days returns soil fattening or pressure green. An appropriate amount of lime or phosphorus fertilizer is added to the pressure on the green to facilitate fermentation and decay of the filling。
(3) early application of base fertilizers contributes to accumulation of nutrients in tree storage, early restoration of tree positions and improved winterization capacity of tree bodies, as well as to the restoration of roots and the flowering of the second year of growth and the prevention of age and age。
December
Management purposes:
The application of organic inorganic compound fertilizers depends on the age of the plum tree and the number of adrenaline fruit, winter clean-up gardens, deworming or tree bodies with lime oil。
Management highlights:
(1) the application of leaves and trunks from 300 to 500 times the copper chloride solution in combination with the winter clean-up park promotes the sterilization of leaves and trees。
(2) fertilizer before the proper application, 5kg urea per soil application, 0. 15 kg urea, 36% potassium sulphate compound fat 0. 15 kg, pre- and pre- and pre- and post- and post-circum-circum。
San hua li's disease control:
1. Sanhua li hong dynasty
Plum red spot characteristic:
The yellow, near-round specter on the side of the leaf, which rises slightly, becomes thicker gradually, and produces a deep red, small dot-shaped spores that are buried in the womb。
Methods of response:
(1) cleaning of sick leaves during the winter, deep burial of the fruit and spraying of 0. 5:1:100 bordeaux。
(2) spraying at the end of the flowering season and at the end of the sprout and during the expansion of the fruit, in conjunction with the prevention of diseases such as anthrax platinum, the use of beryllium (software, etc.) or dyson manganese zinc + enzyme (or ether acetal) or enzymes + fluoride, respectively。
Tsinghua lee powdery
Methods of response:
(1) to improve the permeability of orchards in conjunction with the cutting of gardens, care should be taken to de-humidize the gutter。
(2) in combination with anthrax, 50% of the permethrin (triper) or tetrafluoroether, baracter, etc. Can be sprayed 2-3 times in spring time and 10 days in early fruit to control the occurrence of the disease。
Tsinghua li wing
Measures to combat the vermin:
(i) protecting the use of natural enemies: to avoid, as much as possible, the use of wide spectrum insecticides, such as pyrethrin and organophosphorus pesticides, and to avoid the use of plentiful substances for natural enemy activities
(2) combining a cutter garden: the combing of the branches and the burning of the twigs are concentrated; also the swirling of the worms on the dry branches can be easily brushed with a hard brush。
(3) rational selection, timely spraying。
(b) the best use of high-quality oil emulsions for winter clean-up, with a small amount of homogenized fruit spray
In the spring (march-may) or autumn (september-october), the early incubation of insects spread, with the use of aphids and a small amount of poison to kill。
4. Sanhua lee anthrax
Prevention of anthrax:
(1) clearing of disease branches, dead branches, intensive burning of disease fruit; improving the permeability of orchards in conjunction with cutting and cutting; rapid removal of disease results and elimination of disease centres。
(2) spray one or two times in the bud and during the expansion of fruit, or antholene。
(3) a 1:100 boldolum was sprayed once in the winter clean-up park, and the mantle was painted white。
5. Sanhua lee fluid
Measures to combat plume flow glue:
(1) peaks are converted to soil, organic fertilizers are applied and tree positions are enhanced。
(2) drained water is wet, too dry to pour water, and soil is wet and balanced。
(3) trees are solid and free of steroids, geddine worms, pests such as nasal worms in time to reduce mechanical injuries。
(4) scratch of the glucose of the disease, painted with 1:1:5 bordo fluid and white trunks of winter lime water。
(5) spraying of high-quality folic fertilizers to ensure that a large number of herds are replenished with sufficient nutrients to add boron (per gram) to the annual winter fertilization
Zhang hua li's smoking problem
Pathological: contaminated by the moist field of the same wing pests (shellworms, aphids, etc.), fungi parasite. Pests are severe and wet and depressed。
Zhang hua li pest classification
Aphids:
Aphids use 2. 5% lice more than 1,500 times, or 40% of losbane 800 to 1,000 times, or 50% of logos 800 times, when spring blooms are not open。
Pests such as peacheaters and rollers:
Peaches, cortex, moths, gold turtles are lured to insects using black light lamps, sugar, vinegar, etc.; 40% of them can also be sprayed with 80-1,000 times more than or 2. 5% more than bromocypermethrin。
Skyox:
In may-june, the buffalo regularly checked the trunks and found insect dung, wood crumbs, eggs, i. E. Scraped with a knife or stabbed with wire, or injected 80 per cent of the diarrhea 600-fold fluid into the larvae; the plaster sulfur mixture could also be painted on the main branch or trunk。
