Abstract

The invention discloses a method for preventing cowpea seedlings from overgrowing. The method comprises the following steps: 1, seeding density is inadvisable to be larger, and a ground cover mulch is removed timely after 30 percent of seedlings emerge; 2, thinning and field planting are performed timely; 3, ventilation and light penetrating are enhanced, and temperature and humidity are controlled; 4, nutrient and water management is reasonably performed; 5, overgrowth is controlled through a medicament. Once the overgrowth occurs, except the relevant measures, the overgrowth can also be controlled by mixing the 2,000 to 2,500 times dilution of 50 percent chlormequat chloride with Jiumiao iodine alginate spray. According to the method for preventing the cowpea seedlings from overgrowing, the yield of cowpeas is improved, and the method is suitable for being popularized and applied in large-scale vegetable plantations.

Description

A kind of method preventing the excessive growth of cowpea rice shoot

Technical field

The present invention relates to proportion of crop planting field, particularly a kind of method preventing the excessive growth of cowpea rice shoot.

Background technology

Cowpea has another name called long beans, carob, fresh kidney beans, angle beans, rice bean, waist beans, band beans, opotism beans, chopsticks beans, belongs to pulse family Vigna annual herb plant.Cowpea is edible with tender pod, and its nutrition is abundanter, can stir-fry and eat, cold and dressed with sauce, salt marsh, processing pickles and solarization fresh kidney beans do.

At present, the plantation for cowpea still continues to use conventional method, namely live, water and fertilizer management, spraying pesticide diseases prevention worm, gather, the cowpea output of this method results is generally low, and the key factor restricting cowpea output is the excessive growth of rice shoot.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of method preventing the excessive growth of cowpea rice shoot, and improve the output of cowpea output, proper scale truck garden is applied.

For achieving the above object, a kind of method preventing the excessive growth of cowpea rice shoot that the present invention proposes, it comprises the steps:

1, thickness of sowing should not be too large, in order to avoid seedling is crowded after emerging.Meanwhile, emerge about have 30% after remove mulching material in time.

2, thinning in time and field planting.First about 20 days of field planting, usually there is overcrowding phenomenon in rice shoot, now should suitable mobile rice shoot, makes size rice shoot separately, and expand the living space of individual plant.

3, strengthen ventilation and penetrating light, control epidemic disaster.Ventilation and penetrating light all should be carried out after rice shoot is unearthed, before field planting, reduces temp. and humidity, strengthen cold acclimation, control the undue growth of rice shoot.

4, rationally rich water quality management is carried out.In the preparation of Nutrition Soil, phosphorus, Potassium Fertilizer should be focused on, control nitrogen fertilizer amount.Strictly in seedbed control moisture and topdress, when needing to topdress, can not nitrogen fertilizer application partially.

5, medicament Spindling control.Once there is rice shoot excessive growth, except taking above-mentioned related measure, also available 50% chlormequat 2000-2500 times of liquid mixing is sprayed with regard to seedling iodine alginate.

A kind of method preventing the excessive growth of cowpea rice shoot proposed by the invention, improve the output of cowpea output, proper scale truck garden is applied.

Embodiment

Prevent a method for cowpea rice shoot excessive growth, it comprises the steps:

Claims

1. prevent a method for cowpea rice shoot excessive growth, it comprises the steps:

One, thickness of sowing should not be too large, in order to avoid seedling is crowded after emerging, meanwhile, emerges after about having 30% and remove mulching material in time;

Two, in time thinning and field planting, first about 20 days of field planting, usually there is overcrowding phenomenon in rice shoot, now should suitable mobile rice shoot, makes size rice shoot separately, and expand the living space of individual plant;

Three, strengthen ventilation and penetrating light, control epidemic disaster, ventilation and penetrating light all should be carried out after rice shoot is unearthed, before field planting, reduces temp. and humidity, strengthen cold acclimation, control the undue growth of rice shoot;

Four, rationally carry out rich water quality management, in the preparation of Nutrition Soil, phosphorus, Potassium Fertilizer should be focused on, control nitrogen fertilizer amount, strictly in the seedbed in control moisture and topdress, when needing to topdress, can not nitrogen fertilizer application partially;

Five, medicament Spindling control, once there is rice shoot excessive growth, except taking above-mentioned related measure, also available 50% chlormequat 2000-2500 times of liquid mixing is sprayed with regard to seedling iodine alginate.
