Abstract

The invention relates to the technical field of plant cultivation and concretely relates to a reproductive cultivation method of raspberry seeds. The method comprises following steps: picking up ripen fruits in May to June each year, peeling pulps, cleaning seeds, and continuously cultivating seeds for 3 to 4 months in sterile sand for performing transplanting engraftment; setting up an arched shed above branches after field planting at the placing distance of 50 to 60cm, covering the arch shed with a layer of shading net with the shading degree of 30% between 10 and 16 o'clock every day in September to November and then covering the arch shed with a layer of transparent thin film in the remaining time; covering a transparent thin film all day when December approaches; removing the transparent thin film of the arch shed in March of the second year for field planting and applying a monopotassium phosphate aqueous solution of 1% to 1.5% in concentration to raspberry roots; plucking raspberry buds in the flowering phase of raspberry during the second year for field planting; applying 1-2kg of magnesium fertilizers to per mu in May to June during the second year for field planting; removing the transparent thin film of the arch shed in March of the third year for field planting; and spraying brassinolide (1500-1800 fold), spraying once each month and continuously spraying for 3 months.

Description

A kind of raspberry seminal propagation cultivation method

Technical field

The present invention relates to field of plant growing technology, be specifically related to a kind of raspberry seminal propagation cultivation method.

Background technology

Raspberry is the woody plant of a kind of rose family rubus, a kind of fruit, fruit taste is sour-sweet, the upper length of limb of plant has delavay raspberry herb, the fruit of raspberry is a kind of aggregate fruit, there is redness, gold and black, America and Europe as fruit, China distribute in a large number but the few eat, only there is a small amount of cultivation in area northeastward, more rare on market, raspberry seed oil belongs to unsaturated fatty acid, prostatic secretions hormone can be promoted, there is very high edible and medical value, along with domestic attention development raspberry industry gradually, the area of its plantation and planting scale are also in continuous expansion, but it is serious to there is the obvious destruction Of resources in planting process, the phenomenon that large-scale planting degree reduces and output is not high, the existence of this problem has badly influenced using of raspberry and has been worth and edibility.

Summary of the invention

The object of the present invention is to provide a kind of raspberry seminal propagation cultivation method.

The technical solution used in the present invention is, a kind of raspberry seminal propagation cultivation method, and its cultivation step is:

1, the 5-6 month adopt ripening fruits every year, removing pulp, after clean for fruit seed, put into aseptic coarse sand, watered once permeable every 5 days with the CPPU solution that concentration is 2mg/L, lasting cultivation gets final product transplant planting in 3-4 month;

2, before field planting, planting site is ploughed deeply 30-32cm, every mu of mix 100-120kg ash and 10-15kg Cosan, after mix 10-15 days, field planting is by raspberry seedling, field planting spacing in the rows is 50-60cm, and after field planting, above root bar, 60-80cm place sets up shed, 9-11 month, every day, 10-16 point covered the shade net that one deck shade density is 30% on shed, and all the other times cover layer of transparent film on shed;

When 3, entering December, carry out seedling thinning management, whole day covers layer 2-3 transparent membrane on shed, and every day ventilates 3-5 time, and after seedling thinning, cuttage seeding spacing in the rows is 1-1.5m, and after seedling thinning, every mu of ground applies 100-200kg dried poultrymanure, 10-15kg pulverized limestone, 20-30kg rice husk;

4, when field planting Second Year enters March, removed by the transparent membrane on shed, applying a concentration at transplanting stock root system place is the potassium dihydrogen phosphate aqueous solution of 1%-1.5%;

5, when field planting Second Year raspberry enters the florescence, raspberry petal is extractd;

6, during field planting Second Year 5-6 month, every mu applies 1-2kg fertiliser containing magnesium;

7, when field planting Second Year enters December, whole day covers 1 layer of transparent membrane on shed, and every day ventilates 3-5 time;

8, when field planting enters March on the 3rd year, the transparent membrane on shed is removed, at raspberry foliage spray brassin 1500-1800 times of liquid, monthly spray once, spray 3 months continuously;

The raspberry of maturation of can gathering successively when 9, field planting enters June on the 3rd year.

Beneficial effect of the present invention is, adopts the inventive method plantation raspberry, can significantly improve per mu yield, field planting can enter the phase of abounding with on the 3rd year, and every per mu yield can reach 1420-1500 kilogram, and Mean Fruit Weight can reach 6.8-10.2g, when entering the florescence, flower bud differentiation is good, and percentage of fertile fruit is high, and plant root is flourishing, branch is sturdy, overall resistant to lodging strong with insect pest ability, cultivation cost is low, and picking time may persist to late November.

Embodiment

Below in conjunction with concrete cultivation experiments, the present invention will be described,

Inventor adopts ripening fruits in June, 2013, removing pulp, after clean for fruit seed, put into aseptic coarse sand, waters once permeable every 5 days with the CPPU solution that concentration is 2mg/L, continue cultivation 4 months transplant plantings;

Choose the plot that faces south as planting site, before field planting, planting site is ploughed deeply 30-32cm, every mu of mix 100kg ash and 10kg Cosan, mix is after 10 days, transplant planting, field planting spacing in the rows is 50cm, after field planting, above root bar, 60cm place sets up shed, 9-11 month, every day, 10-16 point covered the shade net that one deck shade density is 30% on shed, all the other times cover layer of transparent film on shed, during in December, 2013, carry out seedling thinning management, whole day covers 2 layers of transparent membrane on shed, ventilate every day 5 times, after seedling thinning, raspberry spacing in the rows is 1m, after seedling thinning, every mu of ground applies 100kg dried poultrymanure, 12kg pulverized limestone, 30g rice husk, during in March, 2014, transparent membrane on shed is removed, applying a concentration at raspberry root system place is the potassium dihydrogen phosphate aqueous solution of 1%, when within 2014, raspberry enters the florescence, raspberry petal is extractd, during in May, 2014, every mu applies 1g fertiliser containing magnesium, during in December, 2014, whole day covers 1 layer of transparent membrane on shed, ventilate every day 5 times, during in March, 2015, the transparent membrane on shed is removed, at raspberry foliage spray brassin 1500 times of liquid, monthly spray once, continuous sprinkling 3 months, when within 2015, entering June year, raspberry plant starts large area result, and fruit is comparatively even, Mean Fruit Weight can reach 6.52kg, strain output can reach 1.53 kilograms, and the fruit phase reaches 3 months, and fruit marketability is better.
