Abstract

The invention belongs to Rice Cropping technical field, more particularly to field of ecology, the control method of rice field ridge weeds.A kind of ecological control method of rice field ridge weeds, is to spray paclobutrazol to the weeds of rice field ridge.The method of the present invention allows the weeds of rice field ridge to be always maintained at dwarfing state, will not rob with Oryza sativa L. and strive growing environment space, Oryza sativa L. is allowed to gather around the more illumination of acquisition, reach mitigation disease pest to cause harm, improve the purpose of yield, and be conducive to the natural enemy for rice grub to provide good habitat, reach and reduce the effect for applying Oryza sativa L. pesticide, make peasant obtain good ecological benefits and economic benefit.

Description

A kind of ecological control method of rice field ridge weeds

Technical field

The invention belongs to Rice Cropping technical field, more particularly to field of ecology, the control method of rice field ridge weeds.

Background technology

Oryza sativa L. is southern staple food crop, peasant mainly take when rice field ridge weeds are removed artificial mow or Person sprays the way of glyphosate, and the two traditional methods have clearly disadvantageous part, and artificial mowing spends in a large number manually, not many Long but long get up, repeatedly cut off, effect is bad, and it is good to herbicidal effect to spray glyphosate, but destroys ecological environment, to water Rice growth causes certain impact, also results in production loss.

Paclobutrazol is chemical agent, its normal usage be watered to rice shoot sprinkling after, rice shoot apical growth can be prevented Advantage, promotes lateral bud（Tiller）Grow.Rice shoot appearance strengthens many tillers, well developed root system for short.It is easy to grower to cultivate, postpones several Its transplanting.

Content of the invention

The technical problem to be solved is to provide a kind of ecological control method of rice field ridge weeds.

The technical problem to be solved is achieved by the following technical programs：

A kind of ecological control method of rice field ridge weeds, is to spray paclobutrazol to the weeds of rice field ridge.

Further, concrete spraying method is：

Early crop corn, applies paclobutrazol 28 ~ 32g of effective ingredient in per mu of the tri-leaf period of ridge weed growth, is watered 150 ~ 200 times of sprays Apply, sprayed after 20 ± 2 days again for the second time, altogether twice；

Late crop corn, after seedling has been inserted, selects weed growth tri-leaf period to spray per mu applies paclobutrazol 21 ~ 24g of effective ingredient, be watered 200 ~ 300 times spray, and spray again for the second time, altogether twice after 20 ± 2 days.

Further, the paclobutrazol adopts 15% paclobutrazol wettable powder.

Further, such as rainy weather before and after spraying, synergist mixing is added to spray.

The present invention has the advantages that：

1. ecological benefits：The present invention manually removes ridge for current peasant and spends big, effect bad and destruction ecological environment Problem, proposes to spray the technology that paclobutrazol controls ridge weed growth, keeps good ecological environment.The technology utilizes paclobutrazol Downgrade, suppress function, the characteristics of do not kill weeds, good habitat can be provided for the natural enemy of rice terrace insect, while rush Downgrade weeds not grow tall, prevent it growing environment space be striven from robbing with Oryza sativa L., allow Oryza sativa L. to gather around the more illumination of acquisition, reach and subtract Hypopathia worm is caused harm, and improves the purpose of yield.

2nd, economic benefit presses down careless effect to control competition of the weeds to Oryza sativa L. with increasing tiller, rush root is downgraded using paclobutrazol Property affect, it is achieved that mitigate input, increase yield, target of increasing the benefit.According to statistics, manually cutting off one mu of weeds needs one day, Spend labour force artificial 100 yuan, will also cut off repeatedly；Spraying glyphosate herbicidal needs 1 kilogram, 10 yuan of meter input, but right Ecological environment does great damage；Spraying paclobutrazol needs 200 grams, spends 7.00 yuan, sprays and spends 14.00 yuan twice, in addition Due to the good environment for protecting Oryza sativa L. natural enemy to stay in, be conducive to the effect for playing natural enemy, reduce the input of pesticide, reach pesticide Decrement application target.The technology has obvious ecological benefits and economic benefit, with certain promotional value.

Specific embodiment

With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention, It is not limitation of the invention.

Embodiment 1

A kind of ecological control method of rice field ridge weeds is：

Early crop corn, applies paclobutrazol effective ingredient 30g in per mu of the tri-leaf period of ridge weed growth, i.e., using 15% paclobutrazol Wettable powder 200g, is watered 150 ~ 200 times and sprays, and sprays again for the second time, altogether twice after 20 days.In case of overcast and rainy before and after spraying Gas, adds synergist mixing to spray.

Late crop corn, after seedling has been inserted, selects weed growth tri-leaf period to spray per mu applies paclobutrazol effective ingredient 22.5g, i.e., Using 15% paclobutrazol wettable powder 150g, it is watered 200 ~ 300 times and sprays, is sprayed after 20 days again for the second time, altogether twice.Spray In front and back such as rainy weather, synergist mixing is added to spray.

Using above method, the weeds of rice field ridge can be always maintained at dwarfing state, will not rob with Oryza sativa L. and strive growth ring Border space, allows Oryza sativa L. to gather around the more illumination of acquisition, reaches mitigation disease pest and causes harm, improves the purpose of yield, and be conducive to as water The natural enemy of rice pest provides good habitat, reaches and reduces the effect for applying Oryza sativa L. pesticide, makes peasant obtain good life State benefit and economic benefit.
