Abstract

The invention belongs to the technique field of cultivating fruit-tree, especially the cultivating technique for white-sand loquat. The object of the invention is to provide a loquat cultivating technique which is characterized by the low cultivating cost, the earlier ripening time of the fruit, the high product yield, big fruit and little seed to replace the current technique which is characterized by the high cultivating cost, the late ripening time of the fruit, the low product yield, small fruit and many seeds. The process of the invention comprises: covering with sun-shading net, controlling the tree body, thinning flower, flower branch and fruit and daily management. The main point of the invention is: covering the loquat tree with black sun-shading net with the shading amplitude of 50%, the covering time is from the middle part of September to the end part of November, to realize advance flower bud differentiation and blooming, and finally reach the object of anti-freezing in winter, ripening advance and producing big fruits with high quality.

Description

White sand loquat culture technique

Technical field

The invention belongs to the fruit tree planting technique field, particularly a kind of white sand loquat culture technique.

Background technology

The white sand loquat is China's distinctive kind in the northern fringe area, loquat production area, south, is the good merchantable brand in the loquat.Its fruit appearance milky of white sand loquat, the easy peeling of pulp soft and succulency, sugar content height (can reach 18 degree), the local flavor spy is good, is rich in multiple nutrients composition and medical value, is the treasure in the fruit, is subjected to liking of consumers in general deeply.But the white sand loquat of China various places does not also form large-scale cultivation at present, only is that small size is sporadicly cultivated; And the maturation time that exists the white sand loquat is slow, yields poorly, and fruit is less than normal, and seed is many, and the higher weak point of cultivation cost makes the commodity of white sand loquat not high.

Summary of the invention

It is slow to the objective of the invention is at the maturation time of existing white sand loquat in the present white sand loquat cultivation, yield poorly, fruit is less than normal, seed is many, the higher weak point of cultivation cost, provide a kind of cultivation cost low, the maturation time morning of white sand loquat, white sand loquat output height, the white sand loquat culture technique that fruit is big, seed is few.

The main points of the technical solution used in the present invention are: in the fall the method that adopts black sunshade net to cover is set in the white sand Loquat-Shaped Cake, make loquat reach flower bud differentiation in advance, the purpose of blooming in advance, it is freeze proof finally to reach winter, premature ripening, the purpose of the big fruit of output high-quality.

The method of operating of white sand loquat culture technique is:

1, the sunshade net covers.White sand Loquat-Shaped Cake tree is carried out the black sunshade net that sunshade net that sunshade uses is selected 50% sunshade amplitude for use; To white sand Loquat-Shaped Cake tree with the time that the sunshade net covers be: mid-September, covering fate altogether was 60～70 days to mid or late November.

2, tree body control.Just adopt happy shape to prune from field planting, every tree stays 3～5 major branches, is trimmed to sphere bundle shape tree crown.The height of tree was controlled at about 2m～2.2m after loquat was grown up.

3, flower thinning fringe, spray and fruit.Flower thinning fringe, spray before blooming; Owing to bloom in advance, late November to early December can obviously be differentiated the well-developed young fruit of headdress flower, can carry out fruit thinning ahead of time; Mid or late December cold wave arrive before the fruit thinning end-of-job, bagging immediately after the fruit thinning, wherein, bagging can play the preventing freeze in winter insulation effect, the used fruit bag of bagging adopts nonwoven or paper to make.

4, daily management.

Irrigate: September～December, it was fine when short of rain, and flower bud differentiation of white sand loquat and flower fringe are grown and needed adequate moisture, should regularly irrigate, and keep soil moisture.

Fertilising.The treelet field planting is digged pit, and imbeds trace elements such as the fertilizer of capacity and phosphate fertilizer, borax; Impose nitrogenous fertilizer every year treelet phase and be main fertilizer 8～10 times.Bearing tree every year is based on the fertilizer of executing phosphorus potash fertilizer 3～4 times; Mix high concentrations of phosphoric acid potassium dihydrogen and borax slightly when play applying pesticide July, suppress to nourish and grow, short its flower bud differentiation with high nutritional agents.

The Shi Huasui of blooming November sprays 15～25PPMGA3, can effectively improve fruit-setting rate and form few seed fruit.Young fruit period December and respectively spray the CPPU of 100～200PPM February～March in next year, can effectively impel fruit to expand, also can strengthen the cold tolerance of fruit.

The branch of over growth is with drawing branch, turning round short its formation bud of a method; Rise July, sets combination with spraying 6BA or CPPU entirely, sprayed once continuous 4～5 times in every month.

The present invention compares with present white sand loquat cultivation method, the maturation time with low, the white sand loquat of cultivation cost early, white sand loquat output height, the characteristics that fruit is big, seed is few.The present invention can make the commodity of white sand loquat improve greatly.

Embodiment

The invention will be further described below by embodiment.

Embodiment:

Mid-September, temperature off the net after measured was not than covering average low 6～8 degree to the black sunshade net of white sand Loquat-Shaped Cake tree covering 50% sunshade amplitude, and humidity also improves relatively; If autumn, rainwater was few, poured water once every 7～10 days, make the loquat flower bud differentiation period that sufficient moisture content supply be arranged; Beginning mid-November flower, Hua Sui sprays 20PPMGA3; Mid or late November is removed the sunshade net that covers on the white sand loquat fruit tree; Carry out fruit thinning when bearing fruit when a large amount of young fruits December, and fruit thinning to each fringe only stays 2～3 young fruits, and young fruit sprays 150PPMCPPU, and put papery fruit bag; Separate bag February in next year, and spray the solution that 150PPMCPPU and topsin are converted 1000 times in water, puts papery fruit bag then; To the late April fruit maturation, this does sth. in advance 20～25 days than the white sand loquat fruit maturation that adopts present white sand loquat cultivation method cultivation.After testing, use heavy average 70～90 grams of fruit of the white sand loquat of culture technique acquisition of the present invention; The fruit appearance milky white, fine hair is complete, and is extremely attractive in appearance; The thin easily stripping of fruit skin, the thick juice of meat is many, and the sugar content of fruit is up to 16～18 degree.
