Abstract

The invention discloses a kind of method for suppressing citrus orchard weeds, suppress the weeds in citrus orchard by planting khuskhus.Using the present invention, only manually cut weeds 12 times during annual 4 May after plantation, apply a little urea, you can ensured khuskhus vigorous growth, reach the purpose for suppressing citrus orchard weeds;And without special plantation every year, simple saving of labor.Practical application shows that khuskhus can keep soil moisture, and summer reduces the soil moisture, winter improves the soil moisture, beneficial to Ci trus growth, and can attract various pests natural enemy and inhabit, the natural control ability of citrus pest is improved, reduces the use of chemical pesticide, it is profitable on ecology.

Description

Suppress the method for citrus orchard weeds
Technical field
The invention belongs to agricultural weed control technology field, more particularly to a kind of method for suppressing citrus orchard weeds.
Background technology
Weed control is the important content of citrus orchard management, traditionally mainly using artificial weeding, machinery mowing and chemistry Weeding.Artificial weeding expends a large amount of manpowers, especially young age citrus orchard, and in the ranks gap ratio is big for citrus tree planting, weed growth ten Divide vigorous;Weeds regeneration is fast after machinery is mowed, it is impossible to controls weeds completely;Though chemical weed control can control citrus orchard weeds, Also it is killed with herbicide several times using common weeds after herbicide, but malignant weed regenerates quickly, ordinary circumstance within 1 year Under 3 herbicides are used continuously in orchard after, the malignant weed such as only remaining nutgrass flatsedge, makes citrus orchard weeds be more difficult to prevent and kill off in orchard; It is additionally, since and uses herbicide, kills edaphon, reduce diversity of soil microorganism, influence Citrus Root to nutrition Absorption, cause mandarin tree yellowing leaf.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of green, ecological efficient side for suppressing citrus orchard weeds Method.
In order to solve the above technical problems, the present invention uses following technical scheme:Suppress citrus orchard weeds method, by Khuskhus are planted to suppress the weeds in citrus orchard.
The method of above-mentioned suppression citrus orchard weeds, is operated according to the following steps:Start to sow post flower in the month in spring 3-5 Grass, depth of planting are no more than 5cm, broadcast bonnet fine earth 2cm;30 days or so after seed sprouting, artificial uprooting weed 1 time, and spread fertilizer over the fields urea; When khuskhus length is to 60-90cm, 15-20cm is cradled 1 time from the ground, cauline leaf covering mandarin tree disk will be cut off, after cradling every time Spread fertilizer over the fields urea;During fall flowering, often row stays 1/3 plant no longer to cradle.
4-5 hours are soaked with 55 DEG C of warm water before khuskhus sowing, are sowed after drying;Or directly broadcast sowing.
The problem of being removed for the weedy difficulty of citrus orchard, inventor establish a kind of method for suppressing citrus orchard weeds, led to Plantation khuskhus are crossed to suppress the weeds in citrus orchard.Using the present invention, after plantation only during the annual 4-6 months artificial weeding 1- 2 times, apply appropriate urea, you can ensure khuskhus vigorous growth, reach the purpose for suppressing citrus orchard weeds;And without every year special Door plantation, simple saving of labor.
Compared with citrus orchard tradition weeding system, the present invention has following prominent characteristics:The growth of khuskhus summer is rapid, straight Vertical stem can suppress orchard weed growth, while cooling moisture-retaining effect is played to soil;Branches and leaves are soft simultaneously, nutritious, cradle Mandarin tree disk is covered, perishable formation organic fertilizer, promotes Ci trus growth;Khuskhus have rhizobium to improve soil with fixed nitrogen Nitrogen content;Khuskhus can attract various pests natural enemy and inhabit, including hunt stinkbug, wasp fly, spider, ladybug etc., and season of flowers can To attract parasitic wasp, natural contral citrus pest ability is improved, reduces the use of chemical pesticide, it is profitable on ecology.
Embodiment
General principle
Khuskhus are tropical pulse family perennial grasses, and leaf amount is enriched, and cauline leaf is soft, and nutrition content is high, cuts off covering Mandarin tree disk can rot to form organic fertilizer quickly, promote the growth of mandarin tree;Khuskhus well developed root system, taproot and lateral root raw Root nodule, the nitrogen content in soil can be increased with fixed nitrogen;Khuskhus erect plants, when growing vigorous period branch formation closing, The growth of other weeds of orchard can be suppressed, while in summer high temperature, play a part of moisturizing cooling to soil, utilize citrus The healthy growth of tree.
Khuskhus fall flowering result, voluntarily land after seed maturity, new plant is grown in next year germination again.
Vigorous period is grown in khuskhus, various pests natural enemy can be attracted and inhabited, including hunt stinkbug, wasp fly, spider, ladybug Deng season of flowers can also attract various parasitic wasps, strengthen orchard natural contral citrus pest ability, reduce chemical pesticide Use, it is profitable on ecology.
Concrete operations
Start to sow khuskhus in the month in spring 3-5, depth of planting is no more than 5cm, broadcasts bonnet fine earth 2cm;After seed sprouting 30 days or so, artificial uprooting weed 1 time, and appropriate urea is spread fertilizer over the fields, form covered ground within after planting 2-3 months, suppress weed growth; When khuskhus length is to 60-90cm, 15-20cm is cradled 1 time from the ground, will be cut off cauline leaf covering mandarin tree disk, is spread after cradling every time Apply appropriate urea;During fall flowering, often row stays 1/3 plant no longer to cradle, and it is yielded positive results, next after being landed so as to seed maturity Germinate in year long seedling again.
Wherein, 4-5 hours are soaked with 55 DEG C of warm water before khuskhus sowing, is sowed after drying, germination percentage can be improved, can also Directly broadcast sowing.
Application example
With reference to the above method, from Guangxi Zhuang Autonomous Region, herding research institute buys Stylo seed, autonomous in Zhuang nationality in Guangxi Area Xiangzhou County great Le towns Lv Tang villages carry out the plantation demonstration of citrus orchard khuskhus, the plantation of the first tenday period of a month in May, and early June artificial weeding 1 time is simultaneously A little urea is spread fertilizer over the fields, mid-August, plant height reached 90-100cm, and khuskhus growth district without other weeds, is also sent out completely The pest natural enemies such as stinkbug, wasp fly, spider, ladybug are hunted on existing khuskhus to inhabit.Plantation khuskhus orchard does not use herbicide.
