Abstract

A cultivation method of a big-fruit date tree is characterized in that the aim of preventing big dates from cracking is achieved by the cultivation method which comprises controlling growth heights and the number of branches of the date tree, building a vinyl house and applying organic fertilizer. During long-term production practice, the fact is found that because fruits of the big-fruit date tree yulingdang are large in size and contain much water, the dates can crack severely during a crisp maturing period when meeting with rain or wind, and the dates lose edible value and commodity value. Because the production method utilizing the vinyl house is adopted, a good ecological small environment is created for growth of the dates, the problem of fruit cracking during the crisp maturing period of the dates is solved, the yield and the quality of the dates are improved simultaneously, and the economic benefit and income of fruit growers are increased.

Two, control plant height and branch, jujube tree is a deciduous tree, as not controlling plant height, lets alone growth; Trunk and the tree-like ten minutes of all looking tall and big, can't build plastic tunnel, therefore must control the height of trunk and the growth of branch, creates conditions for building plastic tunnel; Therefore when deciding strain, the trunk height should be controlled between the 0.4-0.5m, and major branch generally keeps 4-6; And, avoid major branch to do the overlapping of the direction of growth with the orientation of fixing every the branch of rope, influence the growth of fruit branch daylighting and fruit.

Three, the height of control jujube tree tree crown is grasped at 2.5-2.7m the plant height of full tree, and plastic tunnel design height 3m for jujube tree stays the height that ventilates, can not influence the normal growth of jujube tree.

Four, bear fruit jujube tree at the beginning of the spring, autumn defoliation of fruit trees and respectively execute cake fertilizer summer or fertilizer, the fertilizer amount of executing at the beginning of the spring should be more, every strain is grasped at 1.5-2.5kg.

Five, build plastic tunnel: (1) booth is a foundation with removable cemented pier; Anchor block 50 * 40 * 80cm; Shape is up-small and down-big, and the eyelet that inserts steel pipe and fixing of anchor block are left in the centre, according to the number of the size design anchor block of booth area; Be generally one of 5m, establish 20-40 in every mu; (2) on row's fixed mount of the centre of booth, a 3m height is set; The top has the concrete prefabricated bar or the plastic-steel bar of holddown groove; Reinforce the canopy body, the steel pipe height on booth both sides is 1.5-1.8m, also can confirm according to the height of tree; Fixedly clump is plugged steel pipe on the eyelet of clump, fixing greenhouse bracket on steel pipe; (3) skeleton of booth can be with steel pipe or Plastic Steel Pipe; The time of (4) covering the booth Polypropylence Sheet should be grasped-15 days on the 8th August in every year, and on Polypropylence Sheet, reinforces windproof rope, prevents thunderstorm, strong wind.(5) jujube can remove booth after really plucking end, has stored Polypropylence Sheet, the use of waiting for the coming year.

The inventor in long term production, find the beautiful small bell of big fruit jujube tree fruit because big, moisture content is many, therefore; The jujube fruit was met rain or wind and will produce serious dehiscent fruit in the crisp ripe phase, made jujube really lose edibility and commodity value; Because the present invention takes the production method of plastic tunnel, really grow for jujube and to create a good ecologic niche, just avoided the dehiscent fruit problem of jujube fruit in the crisp ripe phase; Improve the quality and quantity of jujube fruit simultaneously, increased economic benefit and orchard worker's income.
