1.5 fight go against a gender
This breed relatively fight a drought, fight waterlogged, disease-resistant capability is stronger also. The winter did not water to July 2002 2001, also not rainfall, still high yield. 2003 5 ～ in August, fall repeatedly heavy rain appears even the cloudy day, still high yield. This breed does not have special plant diseases and insect pests, the disease that has discovered has peach bacterium sex perforative disease, anthrax disease, Hei Xing disease, powdery mildew; Insect pest has moth of aphid, Qian Xie, red spider, pear long-corn of the small bug that eat a heart, red neck. Disease of corrupt of this breed brown is few, without phenomenon of the premature drop before collecting.
2 help advance somebody's career technical point
2.1 soil choice and cultivate density
Adaptability of Yu Xigong sweet a peach-shaped thing is strong, fight a drought is able to bear or endure especially barren, country, upland, flat all can be cultivated successfully, edaphic acid-base value is in with PH value 5.5 ～ 7.5 between relatively appropriate, but should avoid to weigh batch in garden of old a peach-shaped thing cultivated.
This breed cultivates appearance to open business, cultivated density the individual plant row spacing with 3m×4m or 2m×4m is advisable, scale of pollination tree configuration is 5 ∶ 1.
2.2 plastics clip
Appropriate of 4m×2m travel spacing in the rows uses form of “V” glyph tree. This tree form 2 ～ 3a (year) figuration, the bough when figuration reachs his to lengthen a branch to grow 1.4 ～ 1.5m. What 60 ～ 80cm maintains at least between travel is ventilated and pervious to light belt.
Because this strain becomes a flower easily, answer to control branch quantity, fruit amount strictly. Every 667 square metre (mu) branch should be controlled in 8000 ～ 10000, every branch stays if really 2 ～ 3. Should cut gently on clip long put, the fruit-bearing shoot in growing in order to foster is given priority to, fruit-bearing shoot coarseness with 0.3 ～ 0.4cm advisable.
2.3 flowers manage if really
Answer to this breed fruit thinning of strict flower thinning, control takes fruit amount. Scanty go the fruit on double fruit, deformation fruit, ill bug fruit, small fruit, erect fruit and branch of coarseness 0.6cm above, reservation fruit form decorous, fruit size well-balanced, coarseness the good fruit on fruit-bearing shoot of 0.3 ～ 0.4cm. Maintain fruit span 8 ～ 10cm, maintain Xie Guo comparing to be in 50 ∶ 1, maintain 667 square metre (mu) crop 3000kg above. After calm fruit (in May the last ten-day of a month) cover bag of white model film, precautionary ill bug is invaded catch harm fructification, prevent to crack if really, stimulative fructification is chromatic. Cover bag around gush 1 times to kill bug, antiseptic.
2.4 strengthen fat conduit to manage. Close to long hurried is spent
Field planting the 1st year spring sprouts chase after fertilizer the 1st times, later every 15d (day) top application 1, with union of quick result nitrogen, phosphate fertilizer organic fertilizer follows fill water use. Every time individual plant applies urea 10g of 10 ～ 25g, calcium superphosphate, organic fertilizer 5 ～ 10kg, as the amplification of crown of a tree, dose also increases gradually. To the first ten days of a month will stop top application in July, grow in order to control branch tip flourishing, benefit is spent at becoming. The last ten-day of a month will apply autumn fertilizer 1 times in September (give priority to with organic fertilizer) .
