Abstract
The invention discloses a biological control method for organic tea garden weeds. Leguminosae cassia green manure seeds which creep, do not wind and are resistant to drought and leanness are sown among tea tree planting rows in spring, the sowing depth is no more than 5cm, and fine soil of 2cm is covered on the seeds after sowing; weeding is performed once in 30-40 days after the seeds emerge; ground coverage is formed in 2-3 months after sowing; base fertilizer is applied to be combined with a tea garden in winter to turn green manure over to 20cm deep; and from next year, the weeding is performed once on April each year, and the green manure is cut once in summer and autumn. Biological measures of the biological control method can effectively prevent the tea garden weeds from growing in 1-2 years after application, plantation in successive years is not needed, and the biological control method for the organic tea garden weeds is simple, labor-saving and absolutely free of pollution.
Description
Technical field
The present invention relates to the biological control method of a kind of organic tea garden weeds, belong to agricultural technology field.
Background technology
The control of improvement of soil fertility and disease pest and weed is two decisive factors whether organic tea garden can sustainable development, and the tea place can't adhere to that the main cause of organic production is can't leave chemical pesticide to control damage by disease and insect.It is the important content of tea garden management that weed in tea garden is prevented and kill off, main traditionally using artificial weeding and chemical weed control.For organic tea, chemical weed control is restricted, can only use artificial weeding, labor manpower, especially children tea place in age, and in the ranks the crack ratio is big for tea tree planting, and weed growth is very vigorous.
Tea place interplanting green manure is culture fertility effectively, but different types of green manure difference is obviously different aspect the inhibition weed growth.
Summary of the invention
The object of the present invention is to provide the biological control method of a kind of organic tea garden weeds, this biological control measure application 1-2 year can effectively suppress the weed in tea garden growth, and not plantation year after year, and simple saving of labor is definitely pollution-free.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The biological control method of a kind of organic tea garden weeds be spring tea tree planting in the ranks, sowing crawls not twine, the leguminosae cassia green manure seed of drought-enduring impoverishment tolerant, sowing depth is no more than 5cm, broadcasts bonnet fine earth 2cm; Behind the seed sprouting 30-40 days, uprooting weed 1 time; Formed ground and cover in after planting 2-3 month; Combine winter the tea place to apply fertilizer to the subsoil green manure is turned over dark to 20cm; Use 1 year and rise, pull out weeds 1 annual April, cuts green manure summer and autumn 1 time.
Described leguminosae cassia green manure is Chamaecrista Rotundifolia or leatherleaf Cassia tora.
Before the sowing seed being soaked seed with 90-95 ℃ of hot water and wash seed 2-3 time rapidly with clear water behind the 3-5min, is that 1 : 1 stirs seed and fine sand by mass ratio subsequently.Described fine sand is crossed the 2mm soil sieve.
Remarkable advantage of the present invention is: this biological control measure application 1-2 year can effectively suppress the weed in tea garden growth, and not plantation year after year, and simple saving of labor is definitely pollution-free.
