Abstract

The invention discloses a kiwi fruit winter frost damage prevention method. The method includes the steps that foliage fertilizer is applied in October to November at the late growth stage of kiwi fruits, and monopotassium phosphate or phytoalexin or fertility micro element fertilizer is sprayed; after winter comes, more fertilizer is applied, pits at kiwi fruit trunks close to roots are expanded, and rotten manure or pig and cattle pen manure or organic biological fertilizer is applied; the kiwi fruit trunks close to the roots are covered, the kiwi fruit trunks close to the roots are covered with rice straw, straw and weeds in winter, or the kiwi fruit trunks close to the roots are covered with a mulching film; before frost approaches, the mulching film or straw mats cover branches of a kiwi fruit shed frame. The kiwi fruit winter frost damage prevention method has the advantages that tree vigor can be improved through fertilization application, and the stress resistance of the kiwi fruits is improved; the soil temperature can be raised by covering the kiwi fruit trunks close to the roots, so that root systems are protected; by covering the branches of the kiwi fruit shed frame, water loss and cracking of the branches can be prevented. It has been proved that the kiwi fruits can be protected to survive the winter safely.

Description

The method of kiwi fruit preventing freeze in winter evil

Technical field

The present invention relates to the cultivation of kiwi fruit, specifically the method for kiwi fruit preventing freeze in winter evil.

Background technology

Kiwi fruit, in the season of growth and dormancy season, often can run into the long-term low temperature of-8 DEG C-1.5 DEG C, even also can run into the short-term low temperature of-10 DEG C, and low temperature and freezing meeting cause complicated and confused dehydration, and branch lobe is even dead, brings loss to production.At present, the method for conventional fumigation mist is antifreeze, but cost is high, and effect is bad.

Summary of the invention

The object of the invention is to provide a kind of method of kiwi fruit preventing freeze in winter evil.

The technical scheme that realizes the object of the invention is:

A method for kiwi fruit preventing freeze in winter evil, comprises following technical measures:

1. execute foliage fertilizer in the 10-11 phase month in the growth later stage of kiwi fruit, spray the micro-fertilizer of potassium dihydrogen phosphate or protective plant protecting agent or growth promotor for crop;

2. enter after the winter, Shi Chongfei, expands hole to kiwi fruit butt, applies the human excrement or pig cattle pen excrement or the organic bio-fertilizer that become thoroughly decomposed;

3. butt covers, and can use straw, stalk, weeds covering kiwi fruit butt winter, or with the mulch film overlay tree root and stem of certain plants;

4., before frost arrives, cover with mulch film or straw screen or mat on the branch of booth frame for yangtao.

Advantage of the present invention is:

1. can improve tree vigo(u)r by fertilising, improve the resistance of kiwi fruit.

2. cover and can improve soil temperature by butt, protection root system.

3. by covering the branch of booth frame for yangtao, can prevent and treat branch dehydration cracking.

Be proven, above measure can protect kiwi fruit to pass the winter safely.

Embodiment

A method for red kiwi fruit preventing freeze in winter evil, comprises following technical measures:

1. execute foliage fertilizer in the 10-11 phase month in the growth later stage of kiwi fruit, spray concentration is 0.2%-0.5% potassium dihydrogen phosphate, 30 kilograms of every mu of consumptions;

2. enter after the winter, Shi Chongfei, expands hole to kiwi fruit butt, applies the human excrement or the pig cattle pen excrement that become thoroughly decomposed; 100 kilograms every mu, or with " large three without " organic bio-fertilizer, 40 kilograms every mu;

3. butt covers, and can use straw, stalk, weeds covering kiwi fruit butt winter, thickness 10-20 centimetre, or with the mulch film overlay tree root and stem of certain plants;

4. before frost arrives, cover with mulch film or straw screen or mat on the branch of booth frame for yangtao, when arrive spring, remove.
