Description
Technical field
The invention belongs to field of plant growing technology, be specifically related to a kind of method that improves 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 areas of the whole district have 0.83 hundred million hectare, account for 67% of whole district's land area, account for 26% of Chinese native pasture area; Wherein most of position is high and cold area.At present, Tibet livestock is still herded as main taking tradition, and winter-spring season herbage extremely lacks, and domestic animal is lost flesh seriously, seriously limits the sustainable development of local livestock breeding.Set up the sown pasture of high yield and high quality and supply with imbalance to alleviating Alpine-arctic Pastoral grass poultry, promote local animal husbandry development and there is important facilitation.
The high quality forage kind of suitable high and cold area sown pasture is few, and in the sown pasture of setting up, ， Jian Kuo pea, because the better and careless output of cold resistance is higher, is often used as the first-selection of high and cold area cultivation leguminous forage.Jian Kuo pea (Vicia sativa) 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 plantation all over the world, grain, material, careless dual-purpose, be 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 910 DEG C of accumulated temperature, and when sowing, accumulated temperature is 1700～2000 DEG C, 26～28 DEG C of the optimum temperatures of seed sprouting.Depend on to a great extent breediness and weather conditions breeding time, generally from being seeded into ripe approximately 100～140 days.In Rikaze, Tibet, Nan Deng high and cold area, mountain plantation arrow Kuo pea area is larger, is that one of careless main source is store in domestic animal Winter-Spring.
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 from the ground such as Gansu, Shaanxi and buys, and cost is higher.The self-produced seed of peasants and herdsmen is the by product of forage grass mostly, and production still, in disperseing disordered state, gather in the crops usually variet complexity of seed, and seed production is not high.So carrying out Jian Kuo pea seed production localized production is the task of top priority.Existing problem 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 that improves 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 that improves 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 to spray the time be when ， Jian Kuo pea enters pregnant flower bud phase and full-bloom stage, respectively to spray once 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, described in, spray and need, after at 14 in sunny calm afternoon, spray in latter 10 hours and need fill spray if any rainfall.
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.
To obtain Jian Kuo pea output the highest in sowing with this understanding.
Preferably, described field management is will carry out in time the management of damage by disease and insect and weeds in field after spraying, and suitably regulates irrigation situation according to local climate, prevents that excessive growth from appearring in plant.
Further, described high and cold area is Qinghai-Tibet Alpine-arctic Pastoral and the agriculture and animal husbandry ecotone of height above sea level at 2800-3800 rice.
Use method of the present invention, can make arrow Kuo pea seed output significantly improve (output improves 55%-151%), promote provenance support is provided for arrow Kuo pea establishing in large scale, can produce good economic benefit.
