5.3) sublateral shoot pinching again when 35 ~ 40cm, retains weeping branch bar, removes the upright branch of prosperous length, ensures annual bearing.
6) balance fertilizing:
6.1) the field planting tree childhood of 1 ~ 2 year, repeatedly will topdress and attack tip expansion tree crown, adopt the principle using sufficient base fertilizer and execute, mu fertilizer 300 jin,
(1) join and execute a small amount of instant nitrogenousfertilizer early stage, then joined the people and animals' fecaluria or methane liquid executing and become thoroughly decomposed, add superphosphate leachate in right amount;
(2) start to topdress the last week putting the tip, within every 15 ~ 20 days, impose 1 time, continuous 2 ~ 3 times;
(3) after August based on control shoot, multiplex phosphorus potash fertilizer, impels the aging and flower bud differentiation of branch to be formed;
(4) dell basal dressing is dug after 1O month, strain organic fertilizer 3 jin;
6.2) bearing tree, general point of 3 fertilising,
(1) rudiment is fertile, and generally use before unit's rudiment in the middle of the month, biological organic fertilizer 3 kg is executed in strain, digs annular groove and applies;
(2) fruit-promoting fertilizer, in young fruit fertilising in mid-term, now fruit expands rapidly, young sprout and root system start growth, need a large amount of nutrient, based on quick-acting phosphorus, potash fertilizer, liquid dung 5 kg that becomes thoroughly decomposed is executed in strain, add the centesimal green mixed liquor that protects carry out foliage-spray with the potassium dihydrogen phosphate of 3 percent again, as more prosperous in tree vigo(u)r can Shaoshi;
(3) fruit picking is fertile, digs 1.5 ~ 2m, wide 35cm, dark 50cm dell in tree crown both sides, at fruit picking one week rear strain organic fertilizer 3 kilograms, to recover tree vigo(u)r, should increase and increase fertilizer application amount along with the tree crown amount of bearing fruit.
7) tree crown regulation and control and flower and fruit management:
7.1) tree crown regulation and control, the growth of kiwi fruit young sprout just meets rainy season, young sprout is vigorous especially, except carrying out pruning control shoot, also to be aided with controlling the treetops and hastening blossom, or pinching of pinching, effective control young sprout increases and promotes flower bud differentiation, become annual bearer should thank spend after young sprout 5cm long time, spray 1 centesimal green foliage fertilizer nutrient solution that protects and improves colored matter, spray 1 amino acids foliage fertilizer again at the florescence;
7.2) when young fruit soya bean is large, sprays 1 amino acids foliage fertilizer in conjunction with sterilization, insecticide, not only improve Fruit-setting rate, and fruit increases obvious especially;
7.3) reasonable fruit thinning, from inside outwards, first up and then down, first removing fruitlet, malformed fruit, sick wormed fruit, is secondly towards sky fruit, without the fruit on leaf fruit branch, the fruit that position of selecting and remain grows downwards with fruit branch both sides as well, on same fruit branch, fruit spacing is 4 ~ 5cm, long fruit branch stays fruit 3 ~ 4, and medium fruit branch stays fruit 2 ~ 3, and fruit spur, boundray branch stay fruit one or do not stay.
