Techniques of early grape yield


. (1) irrigate and fertilize. Border or furrow irrigation commonly used, the terrain is not normal, can be shortened Qimian, sub-irrigation, and the early formation, improve irrigation efficiency. Each watering should be drenched, loose soil after watering weeding time, back to base to prevent soil compaction. To ensure that grape yield, we should note the following four periods cast East fertilization. Germination ago, before germination in spring water. Generally the end of February or early March to. Due to temperature rise in the spring period, watering should be small, 20-30 cm away from the rhizosphere at the side of ditching or playing water furrow. Per acre with irrigation facilities into the urine index i0 ~ l5 kilograms. Flower early, that is pouring in about a month before flower water, promote differentiation, so that flowering and tidy, improve fruit ratio, can be combined with water from Urea Fertilizer l0-15 kilograms. Expansion of fruit too, that flower after the end of the rapid expansion began when the young fruit, and poured a 2 l water, the P and K of the facilities-based, while paying attention to drainage. Fruit after harvest, depending on the circumstances of a 2 pour l of water, frozen in the land before pouring frozen water, with water facilities into the basic fertilizer, and general use of Summer, that is, between the lines in the tree to open a deep 3O a 5O cm wide 4O cm channel,[link widoczny dla zalogowanych], applied into farm manure, and soil to fully mix well casing. (2) pest control. Not in the bud and leaf bud 3-5 degrees before the spray station agent sulfur stone powdery mildew and black blast fat governance and eradication of the bacteria on the body of the tree eggs. From early May, the periodic spraying of i: o. 5-2 �� times the Bordeaux mixture to prevent the occurrence of anthracnose in fruit can be sprayed 40% of the carbendazim 1000 times, prevention from rot, downy mildew. (3) summer pruning and other tree management. Kyoho low fruit cultivars, severe fruit drop falling, while the formation of flower buds of the variety has the year, flowering habits, to strengthen the summer yield management is the key measure that year. Specific technical: �� Maya left tip. After germination in spring, leaving 3-5 dendrites per hole, the top left of each dendrite a Fushao, the rest erased. Dendrite length to 0.5 meters, the bondage to the wire, the general multi-sector framework Zhuman surface. �� topping and flower. In mid-June on, playing to the branch tip Xu, around late January or in e apical 2-3 cut branches to promote the flower Mang 3, 1989 - * 81 - * identification of mushroom species Zhan Henan study Department of Plant Protection Agricultural University, Taiwan, Zhang Zhen Yu mold should be dipped in recent years, China, mushroom production has developed rapidly, species name of the rhyme stick promiscuity heavier. Different name and with the currency} heterogeneous same name is common, these problems of rent to the mushroom production has led to great difficulties and losses, therefore,[link widoczny dla zalogowanych], rapid, j speech learn to carry out identification of mushroom species defecate quickly pour positive bacteria Name messy phenomenon is necessary. One, materials and methods from the passage of a mushroom strain vaccine Building No. P05Pl9P120P234 tested for: the antagonist tested in 1935 before the trial l5 5i Ten strains selected strains and Han introduced since 1985 a total of 20 strains, whose name and m source in Table 1 with the antagonism of two peroxidase isozymes Kam house methods. I, Zhuo antagonism off after the injection of sterile PDA medium in petri dishes, each dish of three different strains were access, 25c thermostat inside the home for 7 days, the mycelial growth condition to be seen. 2,[link widoczny dla zalogowanych], peroxidase isoenzyme test (1) access to the tested strains were flasks of liquid medium (potato and wheat,[link widoczny dla zalogowanych], Zhu Zhi, glucose), in 25. C incubator incubated 2 days, and then shaking on a shaker for 5 days by filtration, at low temperature, the same amount of mycelium were added to the electrode buffer, ground into a paste using a mortar slurry, centrifuge (1OOOO transfer / min) 3O minutes, supernatant, packaging in vitro, cryopreservation standby. (2) electrophoresis conditions: by polyacrylamide gel electrophoresis, the stacking gel was 4%, 7% of the concentration of isolated limb electrode buffer Gly-Tris (pH8.0), plus every kind of hole injection volume was 50 micro- l, steady flow regulator electrophoresis, electrophoresis to 3MA / tube current regulator 4. c environment for about 3.5 / j, time. (3) staining: Remove the plastic Gui, after washing with distilled water into the ascorbic acid re-_ - _ stained benzidine staining solution for 30 minutes, you can appear blue bands, and then washed with distilled water, placed in 7% acetic acid solution Star brown,[link widoczny dla zalogowanych], observation saved. =, Results and analysis (a) the antagonistic relationship between mushroom strains strains of different species to each other at the same level pull on the spread and inhibited the growth of other hyphae in the contact points have thicker and differentiation. Pick a flower before the @ b, the appropriate flower thinning, flowering and select a two Fushao l growth, inflorescence to stay l0 leaf topping, and pinch to the inflorescence appropriate to promote fruit set. �� attention to training the tree was buried, not lust the second fruit, lay the foundation for the third year in high yield.
