Abstract
The invention provides a kind of method improving high and cold area Jian Kuo pea output, comprise seeding and seedling raising, preparation growth regulating reagent and spray reagent, field management step; Described reagent is paclobutrazol solution.Use method of the present invention, can Shi Jian Kuo pea seed output significantly improve, output increased 55%-151%, Wei Jian Kuo pea establishing in large scale is promoted and is provided provenance support, can produce good economic benefit.
Description
Technical field
The invention belongs to field of plant growing technology, be specifically related to a kind of method improving high and cold area Jian Kuo pea output.
Background technology
Pastoral area, Qinghai-Tibet Platean is one of the main Grazing Ecological Systems of China and maximum meadow system, and all kinds of native pasture area of the whole district has 0.83 hundred million hectare, accounts for 67% of whole district's land area, accounts for 26% of Chinese native pasture area; Wherein most of position is high and cold area.At present, Tibet livestock is still herded based on tradition, and winter-spring season herbage extremely lacks, and domestic animal is lost flesh seriously, the sustainable development of the local livestock breeding of serious restriction.The sown pasture setting up high yield and high quality is uneven to the grass poultry supply of alleviation Alpine-arctic Pastoral, promotes local animal husbandry development and has important facilitation.
The high quality forage kind of suitable high and cold area sown pasture is few, in the sown pasture set up ， Jian Kuo pea because of cold resistance better and Herbage harvest is higher, often by the first-selection as high and cold area cultivation leguminous forage.Jian Kuo pea (Viciasativa) is annual leguminous forage, and its cauline leaf is tender, nutritious, good palatability, and grass yield is high, and seed is also the good feed of domestic animal.It is remarkable that the multiple cropping rotation of crops improves soil fertility.Generally planting all over the world, grain, material, careless dual-purpose, is also one of main green manure crop of improving soil fertility.The happiness of Jian Kuo pea is nice and cool, and results green fodder requires accumulated temperature 910 DEG C, and during sowing, accumulated temperature is 1700 ~ 2000 DEG C, the optimum temperature of seed sprouting 26 ~ 28 DEG C.Breeding time depends on breediness and weather conditions to a great extent, generally from being seeded into maturation about 100 ~ 140 days.In Rikaze, Tibet, arrow Kuo pea area is planted comparatively greatly in Nan Deng high and cold area, mountain, is one of main source of domestic animal Winter-Spring storage grass.
Jian Kuo pea " west herds 324 ", " west herds 333 " are topmost two kinds of current this area popularizing planting.But local establishing in large scale Jian Kuo pea seed used mainly relies on to be bought from the ground such as Gansu, Shaanxi, and cost is higher.The self-produced seed of peasants and herdsmen is the by product of forage grass mostly, produces and is still in dispersion disordered state, results seed usually variet complexity, and seed production is not high.So carrying out Jian Kuo pea seed production localized production is the task of top priority.Problem existing in producing according to Jian Kuo pea seed, selecting suitable growth conditioning agent to improve seed production is a kind of effective method.
Summary of the invention
The object of this invention is to provide a kind of method improving high and cold area Jian Kuo pea output, it can improve the output of Jian Kuo pea seed effectively.
The invention provides a kind of method improving high and cold area Jian Kuo pea output, comprise seeding and seedling raising, preparation growth regulating reagent and spray reagent, field management step; Described reagent is paclobutrazol solution.
Preferably, the concentration of described paclobutrazol solution is 100-400mg/L.
Preferably, described in spray the time be respectively spray once when ， Jian Kuo pea enters pregnant flower bud phase and full-bloom stage mid-June to mid-July, phenology enters the pregnant flower bud phase with 80% Jian Kuo pea in meadow or full-bloom stage is as the criterion; Spraying position is arrow Kuo pea complete stool, comprises the position on the ground such as branch, leaf, inflorescence.
Preferably, spray and after sunny calm at 14 in afternoon, need spray in latter 10 hours and need fill spray if any rainfall described in.
Preferably, in described seeding and seedling raising, seeding quantity is 60-80kg/hm
2, drilling, seed level is 4-7cm, line space 25-30cm.
Further, in described seeding and seedling raising, seeding quantity is 80kg/hm
2, drilling, seed level is 5cm, line space 25-30cm.
Sow that to obtain Jian Kuo pea output the highest with this understanding.
Preferably, described field management is the management will carrying out damage by disease and insect and weeds in field after spraying in time, and suitably regulates irrigation situation according to local climate, prevents plant from occurring excessive growth.
Further, described high and cold area is that height above sea level is at the Qinghai-Tibet Alpine-arctic Pastoral of 2800-3800 rice and Agro-grazing ecotone.
Use method of the present invention, can Shi Jian Kuo pea seed output significantly improve (output increased 55%-151%), promote Wei Jian Kuo pea establishing in large scale provenance support is provided, good economic benefit can be produced.
