CN104255383A - Date tree germination-accelerating and seedling-culturing technology suitable for arid region - Google Patents

Abstract

The invention discloses a date tree germination-accelerating and seedling-culturing technology suitable for an arid region. The planting technology is realized by adopting the following steps: (1) selecting uniform and full dates without plant diseases and insect pests, dewatering the dates until the water content is less than 15% and storing the dates in a sealing manner; (2) pre-processing the dates; (3) performing germination acceleration treatment to enable the germination rate of seeds to be above 85%; (4) culturing seedlings artificially; (5) transplanting and field-planting; (6) performing growth management, namely, irrigating every 2-3 days half a month after the transplantation, after seedling survival, irrigating every 10-15 days during the period from the last ten days of March to middle ten days of May, spreading 5 kg urea per each mu by combining with water irrigation after the end of May, and dressing diamine 10 kg per each mu by combining with intertillage and weeding after the second water irrigation for fields with relatively low soil fertility.

Description

A kind of jujube tree Pregermination and seedling breeding technology being applicable to arid area

Technical field

The present invention relates to a kind of planting technology, particularly a kind of jujube tree Pregermination and seedling breeding technology being applicable to arid area, belongs to agricultural plantation technology field.

Background technology

Arrow-leaved oleaster belongs to Elaeangnaceae Elaeagnus deciduous tree or shrub, is the economy plough seeds integrated functions as one, is widely used in food, medicine, papermaking, feed, timber, furniture etc. at present in China.The branch of arrow-leaved oleaster, leaf, flower, fruit all have development and utilization and are worth.Narrow-leaved oleaster has again anti-blown sand, resistance to salt marsh, resistance to dry morning, thin, the easy breeding of high temperature resistant, resistance to hemorrhoid, an adaptable feature, is transformation arid, one of sand ground, wasteland, salt lick fine tree species of afforesting.Arrow-leaved oleaster is non-pulse family nitrogen-fixing plants, and its rhizobium play a part very important in fixed nitrogen and improvement soil.Arrow-leaved oleaster seed coat hard and compact, cannot be sloughed by seed coat by the method for mechanical exfoliation, cause percentage of seedgermination low, emerge uneven, seedling quality also can not be guaranteed.

Summary of the invention

The present invention is based on existing jujube tree planting technology, adopt the principles of science of novelty, propose a kind of jujube tree Pregermination and seedling breeding technology being applicable to arid area, it greatly saves labour, reduce jujube tree planting cost, improve jujube tree survival rate, enhance the benefit of plantation jujube tree, the disease resistance of jujube tree and insect pest ability are strengthened, reaches the object of high yield and high quality.

The technical scheme that the present invention solves its technical problem adopts following steps to realize.

1. select even, full, without the fruit of damage by disease and insect, dehydration makes water content lower than 15%, and sealing is preserved;

2. seed pre-treatment: after being taken out by fruit, put into clear water and soak 16-24 hour, load in nylon yarn bag, rub with water, remove exocarp, clear water is cleaned and pulled out;

3. carry out vernalization process, make the germination rate of seed reach more than 85%;

4. artificial breeding: treat that 60% bud shows money or valuables one carries unintentionally, starts to be placed in husky bed seeding and seedling raising, and nursery selects cave to coil or flowerpot, and matrix is river sand: vermiculite: turfy soil=1:1:1, normal rich water quality management;

5. transplant planting: treat that arrow-leaved oleaster seedling grows to Second Year, generally sentence on late Febuary to March, is with native a small bay in a river to transplant, uses sufficient base manure, with 667m before transplanting ²manuring 5000kg, lOkg diamines, 50kg phosphate fertilizer, 10kg urea is advisable, and after transplanting, pours water immediately;

6. tending management: often pour water once in 2-3 days in two weeks after transplanting, after slow seedling, during late March to mid-May, pour water for 10-15 days 1 time.By the end of May, can spread fertilizer over the fields urine rope in conjunction with pouring water according to every mu of 5kg, what soil fertility was lower can impose a diamines in conjunction with intertill and clean tillage according to every mu of lOkg after second time is poured water.

Beneficial effect of the present invention: a kind of jujube tree Pregermination and seedling breeding technology being applicable to arid area that the present invention proposes, it greatly saves labour, reduce jujube tree planting cost, improve jujube tree survival rate, enhance the benefit of plantation jujube tree, the disease resistance of jujube tree and insect pest ability are strengthened, reaches the object of high yield and high quality, there is larger promotional value.

Embodiment

Below in conjunction with instantiation, the invention will be further described.

2. seed pre-treatment: after being taken out by fruit, put into clear water and soak 16-24 hour, load in nylon yarn bag, rub with water, remove exocarp, clear water is cleaned and pulled out;

3. carry out vernalization process, make the germination rate of seed reach more than 85%;

4. artificial breeding: treat that 60% bud shows money or valuables one carries unintentionally, starts to be placed in husky bed seeding and seedling raising, and nursery selects cave to coil or flowerpot, and matrix is river sand: vermiculite: turfy soil=1:1:1, normal rich water quality management;

5. transplant planting: treat that arrow-leaved oleaster seedling grows to Second Year, generally sentence on late Febuary to March, is with native a small bay in a river to transplant, uses sufficient base manure, with 667m before transplanting ²manuring 5000kg, lOkg diamines, 50kg phosphate fertilizer, 10kg urea is advisable, and after transplanting, pours water immediately;

(3) 6. tending management: often pours water once in 2-3 days in two weeks after transplanting, after slow seedling, during late March to mid-May, pour water for 10-15 days 1 time.By the end of May, can spread fertilizer over the fields urine rope in conjunction with pouring water according to every mu of 5kg, what soil fertility was lower can impose a diamines in conjunction with intertill and clean tillage according to every mu of lOkg after second time is poured water.

More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
