The invention provides a kind of method of preventing and treating tribute mandarin orange dehiscent fruit, effectively can reduce the dehiscent fruit quantity of tribute hesperidium aurantium reality.

In order to achieve the above object, the present invention is by the following technical solutions:

Irrigate: the irrigation work carrying out planting site, rainy season will get rid of planting site ponding in time, rainy season, planting site had seeping phenomenon to be no more than 3 days with standard, want dry season suitably to planting site pouring drought resisting, if dry weather was more than 30 days, water spraying direction irrigation sprayer upwards during pouring, need be adopted to water, cause branches and leaves withered and yellow to prevent tribute mandarin orange trunk lack of water, if arid, below 30 days, can adopt flowing water to water.

Loosen the soil: carry out loosening the soil and weeding work of planting site, strengthen intertillage management, within 30 days, adopting small-sized machine to carry out intertillage loosens the soil once, more than three, it rains continuously, rain stops after soil drying, carries out intertillage comprehensively immediately loosen the soil, after intertillage is loosened the soil to field, available weeds or wheat straw mulching plant ground, and press a small amount of hack.

Fertilising: the fertilising work carrying out planting site, rationally can effectively reduce dehiscent fruit quantity to planting site fertilising, executes farmyard manure and the higher composite fertilizer of Determination of Potassium at tribute mandarin orange fruiting period more, to enrich fruit tissue, increases peel thickness and toughness.

Prune: the pruning work carrying out tribute mandarin orange branches and leaves, in the treelet phase based on light pruning, cutting back is carried out to elongated shoot, cutting back degree is wanted to keep growth balance between each major branch, the first fruit phase will continue the key elongated shoot of cutting back, erase summer shoot, inspire healthy and strong autumn growth, the full bearing period will wipe out the branch that is in the light, sick branch in time.

The more foliage fertilizer of calcium constituent is contained in full-bloom stage, the many uses of young fruit period, before selecting the 8 a.m. that calm cloudy day or humidity are comparatively large, evaporation discharge is little during use foliage fertilizer, suitably can add auxiliary agent at foliage fertilizer, improve foliage fertilizer at epiphyllous adhesion, promote the absorption of calcium constituent.

At tribute mandarin orange fruit growth period, if continuous several days arids, after the rain or irrigate after, pulp absorbs water in a large number, meat and skin are grown and asynchronously cause dehiscent fruit, therefore, to be diligent in when arid with water spraying direction irrigation sprayer upwards to pouring, fruit growth period, arid need just be given and pouring by the method more than once week; Also the urea solution of 0.2% can be adopted to be sprayed on fruit surface at dusk, promote pericarp growth, spray in 5 days once.

As preferably, when applying fertilizer to planting site, the fertilising cycle is biweekly, and fertilization mode, for dig dropping pit at planting site, buries institute's fertilise with soil afterwards.

The invention has the beneficial effects as follows: irrigate when draining in rainy season, arid, can prevent soil moisture from lacking of proper care, avoid fruit and absorb too many moisture and cause pulp expansion dehiscent fruit; Loosen the soil and weeding to planting site in time, the nutrient absorption of fruit tree can be accelerated, promote fruit tree healthy growth; Rational pruning, can avoid part branches and leaves malnutritive and the dehiscent fruit that causes; The toughness of pericarp can be promoted to fruit pouring or sprinkling urea solution and promote pericarp growth, reducing dehiscent fruit probability.

Embodiment

Below in conjunction with embodiment, a kind of method of preventing and treating tribute mandarin orange dehiscent fruit of the present invention is described further:

Rationally management is carried out to it in tribute mandarin orange vegetative period and fruiting period and can effectively reduce dehiscent fruit quantity, planting site ponding is got rid of in time in rainy season, when rainy season, planting site had ponding the 3rd day, use the drainage system of planting site to drain the water away in time, dry season suitably waters drought resisting, when dry weather was more than 30 days to planting site, need adopt during pouring water spraying direction irrigation sprayer upwards give with pouring, to prevent tribute mandarin orange trunk lack of water from causing branches and leaves withered and yellow, if arid is below 30 days, adopt flowing water pouring; Strengthen intertillage management, within 30 days, adopt small-sized machine to carry out intertillage and loosen the soil once, more than three, it rains continuously, rain stops after soil drying, carries out intertillage comprehensively immediately loosen the soil, after intertillage is loosened the soil to field, available weeds or wheat straw mulching plant ground, and press a small amount of hack; Rationally to planting site fertilising, execute farmyard manure and the higher composite fertilizer of Determination of Potassium, to enrich fruit tissue at tribute mandarin orange fruiting period more, increase peel thickness and toughness, the fertilising cycle is biweekly, and fertilization mode, for dig dropping pit at planting site, buries institute's fertilise with soil afterwards; Moderate pruning, in the treelet phase based on light pruning, carries out cutting back to elongated shoot, cutting back degree is wanted to keep growth balance between each major branch, and just the fruit phase will continue the key elongated shoot of cutting back, summer shoot of erasing, inspire healthy and strong autumn growth, the full bearing period will wipe out the branch that is in the light, sick branch in time; The more foliage fertilizer of calcium constituent is contained in full-bloom stage, the many uses of young fruit period, before selecting the 8 a.m. that calm cloudy day or humidity are comparatively large, evaporation discharge is little during use foliage fertilizer, suitably can add auxiliary agent at foliage fertilizer, improve foliage fertilizer at epiphyllous adhesion, promote the absorption changing calcium constituent; At tribute mandarin orange fruit growth period, if continuous several days arids, after the rain or irrigate after, pulp absorbs water in a large number, meat and skin are grown and asynchronously cause dehiscent fruit, therefore, to be diligent in when arid with water spraying direction irrigation sprayer upwards to pouring, fruit growth period, arid need just be given and pouring by the method more than once week; Also the urea solution of 0.2% can be adopted to be sprayed on fruit surface at dusk, promote pericarp growth, spray in 5 days once.
