30, it is preferable that tall oat grass yield and quality was harvested at this time.
Tall oat grass, which harvests, should not rewater in previous week.
Seven, regrowth hair oat harvest time and harvest
10 kilograms per acre of Diammonium phosphate (DAP) are imposed in 3~5 days after first planting oat harvest, are watered in time.Oat root system sprout tillers
Sprouting meeting fast-growth, does not need to be reseeded.Regrowth hair oat harvest time Hulunbeier area is advisable at September 10-15,
Oat breeding time is pustulation period to milk stage at this time.
It receives for test example 1 conventional a kind of pair and mixes a kind of double receipts comparisons with multi items
Test site: bis- team of Hulun Buir Xie Ertala；
Test variety: dam swallow No. 4, dam swallow No. 6, dam oats 3, dam oats 18；
Selection of land: first planting crop is Rice-rape fields, medium fertility plot；
Date of seeding: soil thaws about 10cm, on April 24th, 2017；
First planting harvest time: on June 22nd, 2017；
Regrowth hair harvest time: on September 12nd, 2017.
After harvest, it is 14%-18% through natural drying to water content, weighs, statistical result such as table 1:
The double receipts (comparative example 1) of comparison single variety one kind and multi items mix a kind of double receipts (embodiment 1) production unit areas
The output condition of tall oat grass, multi items mix a kind of pair and receive Herbage harvest double receipts a kind of higher than single variety, and four Cultivar mixtures one
Kind is double to receive forage yield highests.
A kind of double receive of 1 single variety of table mixes a kind of double yield received with multi items
The reason of analyzing this technology.Firstly, harvest tall oat grass production technology takes full advantage of oat twice for primary sowing
Cold-resistant Germination characteristics, the effective accumulated temperature and sunshine time that can preferably utilize high latitude Han Qu.Secondly, single oat varieties
After planting, after first planting grass harvests in the watery stage, although still there is certain sprout tillers power of regeneration, regenerated branch density compared with
It is low, it affects the population photosynthesis of eldish, affect the yield of eldish.Therefore, test selection multi items mixed seeding advantage,
Play the otherness of different growing tall oat grass sprout tillers power of regeneration.Test proves, in the entire life process of oat, with
Pustulation period, milk stage, dough stage, the sprout tillers power of regeneration of oat root system gradually weaken, and multi items more breeding times mixing is broadcast
Kind can reduce or even avoid this problem, when first batch of tall oat grass harvest, in the oat of ripe breeding time have just enter into the pustulation period, can
To guarantee first batch of careless yield, the tall oat grass of late breeding time although there is no enough growths at first batch, due to
Breeding time, relatively late the sprout tillers power of regeneration of root system was strong, it is ensured that regrowth hair branch density, and then guarantee the production of eldish
Amount.Certainly, in experiment it has been found that in first batch of growth course, there is to the competing of light and nutrient between different cultivars
Strive, late breeding time oat varieties in first batch of growth in order to compete light, can obtain in ripe breeding time similarly grow speed
Rate is especially embodied in plant height；When second batch of regeneration, in ripe oat varieties in order to compete light, relative growth with late-maturing oat
Rate also increases, thus it is guaranteed that two batches of careless yield.In addition, since multi items hybrid technology is while guaranteeing Herbage harvest,
Breeding time when harvest is opposite in advance, improves the quality of tall oat grass to a certain degree.
Compare multi items and mix a kind of double each processing tall oat grass yield of receipts: yield is sowed than single variety and is produced when two Cultivar mixtures
Amount improves, and improving most is 4 Cultivar mixtures technologies, therefore selects the double breeding time oat hybrid technologies of four kinds.
The different oat varieties mixing qualities of test example 2 compare the influence of grass yield
Test site: Hulun Buir Ewenki grass animal husbandry experiment station
Test variety: dam swallow No. 4, dam swallow No. 6, dam oats 3, dam oats 18；
Selection of land: first planting crop is sugar grass, medium fertility plot；
Date of seeding: soil thaws about 10cm, on April 20th, 2018；
First planting harvest time: on June 21st, 2018；
Regrowth hair harvest time: on September 6th, 2018.
For other implantation methods with embodiment 1, test result is shown in Table 2:
After harvest, through natural drying to water content 14%~18%, weigh, statistical result such as table 2:
2 different cultivars mass ratio of table is to a kind of double influences for receiving oat Herbage harvest
Note: kind and breeding time code name are identical as table 1.
The combination of different growing kind oat has an impact to oat plant height, branch density and hay yield.Ripe swallow in the middle
Wheat variety quality accounting (2:2:1:1) and when (3:3:1:1) larger, first batch of careless plant height and branch density are relatively high,
Hay yield is also higher.The growth of second batch of oat is then adversely affected, and is shown that plant height and branch density reduce, is caused
The reduction of yield.Correspondingly, causing the growth of first planting grass insufficient when late-maturing oat varieties quality accounting is larger, showing plant height
It is relatively low with branch density, hay yield is affected, still, the yield of eldish is relatively high.Analyze different ripening stages
The reason of economical character caused by variety and quality ratio and hay yield.This is mainly related with competition theory, in ripe oat varieties and
Late-maturing oat varieties is mixed according to certain mass ratio, directly affects the accounting of each kind emergence, the lower kind of ratio,
It is on a sticky wicket in the competition of light and nutrient, the confidence of competition can be lost.When the mass ratio of several kinds is in certain range
Interior, each kind sees hope in the competition of light and nutrient, and then in growth on the ground, late variety tachyauxesis,
During regrowth hair is regenerated, medium variety also continues the competition of light and nutrient, promotes growth.Comprehensive each mass ratio, four product
Kind of mass ratio is according to 1:1:1:1 mixed seeding, two batches of grass yield highests, there are the difference of conspicuousness compared with other each groups, p <
0.05。
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should be regarded as
Protection scope of the present invention.
