Standard cultivation techniques Yongding tomato

As the provincial standard tomato cultivation demonstration area. Currently, the county implemented standard cultivation techniques tomato garden area 2333.3hm, the average yield per 666.7m over 2160kg, than the average 8% increase over park; a rate of fruit quality fruit of more than 6o%, than the average Garden increased by 30 percentage points, economic efficiency improved significantly. Standard cultivation techniques of tomato now reported as follows. An improvement of infrastructure are located in the county mountain tomato fruit. Most non-standard construction of mountain persimmon garden terrace, the standard is not high, not even terracing. In the standard construction, do not meet the specifications of the terraces, all renovated into a high, horizontal, external high in the low (elevation 10em above), more than the standard 2.5m wide terrace; no terraces, all fish-scale pit expansion , high-scale renovation of connectivity between the communication hole. Bamboo terrace repair ditch along the plane, depth and width of the 20em, conducive to water drainage. Persimmon is far more drought tolerant, but the prolonged drought is not conducive to fruit quality and yield. Therefore, no storage tanks or reservoirs below normal for Shiyuan, generally every 0.67hm repair a 10m of reservoir water during the rainy season when the water too dry and meet spraying water. No road or on imperfect roads Shiyuan repair roads. To do with the roads connecting the main road,[link widoczny dla zalogowanych], connected with the orchard area road work. Trunk road width of 3.5m above normal, rational distribution of cell operating channel, was 2 sticks of pruning too much of the backbone, in particular, had a strong central leader tree is too high, the appropriate part of the backbone Thinning branches, Thinning canopy top 1 or 2 large branches off the head to open a window, so that air and light canopy, dwarf tree , easy to manage. Thinning winter pruning dead branches, weak branches, worms,[link widoczny dla zalogowanych], overlapping branches, and branches. Substantial development is 1 year old branches the following year a good result mother, not cutting back, only to have the appropriate Thinning dense branches. Thinning too dense or unwanted branches of nutrition, enrichment on growth, length 20 ~ 45em length of vegetative shoots left about 1 / 3 of cutting back and do updates alma mater. The result of weak branches, leaving 2-3 buds stub. Result mother on the results of the students more than 3 branches, the results retain the lower one, and left the base 2 to 3 buds stubs, together with the alma mater to the rest of Thinning. Be the backbone retraction drooping branches to raise the results of operations management positions to facilitate the orchard. Leggy branches of the crown bore, with strong growth to remain weak space are sparse, leaving 15 ~ 20em stub, culture results Zhizu; without reservation as soon as possible using the value of Thinning. 3, soil testing and fertilizer. Promotion of organic manure demonstration garden tomato soil testing and fertilizer technology, combined with soil testing and fertilization conditions. 50kg more than the general strains producing trees,[link widoczny dla zalogowanych], plants nitrogenous 0.8I ��g,[link widoczny dla zalogowanych], nitrogen, phosphorus and potassium ratio of 10:6:8. 3 years applied fertilizer as base fertilizer 1st, l0 to l2 late January early February before fruit picking was applied to the main organic fertilizer, fertilizer accounts for half of the year; the first 2 times as strong shoot and flower fertilizer, in 3, the early leaves of spring shoots in mid to late when the show was applied to the squaring to available nitrogen-based; 3 times as stable fruit fertilizer, physiological drop in 1st 6 months after the end of NPK fertilizer applied. Shiyuan the growing season is generally not weeding, removing only the weed, or intercropping Cassia, Cassia and other green manure crops bipinnata. Tall weeds or green manure crops after the mowing or cutting grass covers the ground green pressure to reduce the rainy season, surface runoff, reduce soil erosion; summer to improve orchard humidity and lower surface temperature, the results favor the growth of persimmon; increase soil organic matter content, soil structure; reduced weeding times, lower management costs. 4 protecting flowers and fruits and fruit thinning on the natural result of growing trees in the flowering (late April to May. Early), on the trunk and main branch of the loop peeling, width 0.3 ~ 0.5era, deep of xylem xylem without injury, can significantly improve fruit set. The measures applied in the main producing areas in the county general tomato, the effect is good. Too much time on the results tree thinning, leaving each result mother results 1 to 2 sticks, robust result mother may stay the results of 2 to 3 branches; tip of each branch remain sturdy fruit bearing branches 3 to 4, and the remaining Each branch leave fruit bearing branches 2 or 3, cut worms fruit, small fruit and deformed fruit to enhance the rate of high-quality fruit, fruit thinning is generally 1st physiological drop (mid-June on) for. 5 pest control tomatoes pest less. Main diseases are anthracnose, angular leaf spot and leaf blight park; major cotton pests have persimmon Kuwana, Shi Di gypsy moth worms and persimmon. Combat the winter when the Qing �� Park, closed garden. Dong Jian, clear dead branches, diseased branches, fallen fruit, leaves, concentrated burned; spray 5. Be calcium polysulfide sealing Park, the eradication of overwintering insect source. �� spraying Bordeaux mixture early occurrence of disease, 65% and 70% zinc Dyson mancozeb, etc.; insect pest culling rate of 40% with EC, 9o% trichlorfon crystals to prevent and treat.
