Problems solved by technology

[0003] At present, scholars from different places have done detailed studies on the cutting time and cutting times of forage triticale and Mexican corn, as well as on the multiple cropping of triticale-whole-plant corn silage and triticale-cotton. According to the research report, considering the perennial characteristics of triticale and the strong regeneration of Mexican corn, the two can be multiplanted at an appropriate time to provide grass forage with balanced quality and high yield for animal husbandry, especially dairy farming. , and the relevant research has not been reported yet, the inventors took the "triticale-Mexican corn" multiple cropping model as the research object, and explored its reasonable multiple cropping parameters, so as to optimize their respective biological yield and quality, and provide dairy cows with balanced quality Gramineae Practical application effect of forage grass

Embodiment 1

[0027] Materials and methods:

[0028] Triticale was sown on September 25, 2014, with a sowing rate of 8 kg per mu and a row spacing of 15 cm. The triticale turned green on March 18, 2015, and the triticale was harvested 30 days after turning green (April 17) and 60 days (May 17). * Triticale was harvested from a 50cm square, chopped with a guillotine, weighed and recorded as a whole, and about 500g of a sample was taken by the quartering method. After recording the fresh weight, it was killed at 105°C for 2 hours, then dried at 85°C to constant weight, and recorded. Dry weight, 5 repetitions for each stubble height, and 2 samples of 500g for each repetition as parallel, then the moisture content and dry matter content of triticale can be calculated.

[0029] On April 18, 2015 and May 18, 2015, the triticale harvest area was re-sowed with Mexican forage corn, with a sowing rate of 0.8 kg per mu, and the sowing was carried out at a row spacing of 60 cm and a plant spacing of 2...

[0037] Materials and methods:

[0038] Triticale was sown on September 25, 2014, with a sowing rate of 8 kg per mu and a row spacing of 15 cm. The triticale turned green on March 18, 2015, and the triticale was harvested 30 days after turning green. The height of the stubble was set at 2.5cm and 5.0cm, and the triticale was harvested according to a 50cm*50cm square, and chopped with a guillotine. Weigh and record as a whole, take about 500g sample by quartering method, record the fresh weight, fix it at 105°C for 2 hours, dry it at 85°C to constant weight, record its dry weight, and repeat each stubble height 5 times, each repeat Take two 500g samples as parallel, then calculate the moisture content and dry matter content of triticale.

[0039] Sow Mexican forage corn on April 18, 2015. The sowing rate per mu is 0.8kg. The row spacing is 60cm and the plant spacing is 25cm. The first crop is harvested 100 days after emergence. The stubble height is set to 6cm and 12cm, and the...

Embodiment 3

[0047] Materials and methods:

[0048] Triticale was sown on September 25, 2014, with a sowing rate of 8 kg per mu and a row spacing of 15 cm. The triticale turned green on March 18, 2015. The harvest period was set to 30d and 40d after turning green, and the height of stubble was set to 5.0cm, 7.5cm and 10.0cm. Harvest the triticale from the sample square, chop it with a guillotine, weigh and record the whole, take about 500g of the sample by quartering method, record the fresh weight, fix it at 105°C for 2 hours, dry it at 85°C to constant weight, and record the dry weight , each stubble height was repeated 5 times, and two 500g samples were taken as parallels for each repetition, and then the moisture content and dry matter content of alfalfa could be calculated.

[0049] Sow Mexican forage corn on April 28, 2015. The sowing rate per mu is 0.8kg. The sowing is carried out according to the row spacing of 60cm and the plant spacing of 25cm. The harvest period is set to 80d, ...

Abstract

The invention discloses a multiple-cropping mode of cow roughage triticale-zea mexicana and application of the multiple-cropping mode. The multiple-cropping mode is realized by the following steps: two varieties, comprising overwintering type herbage triticale and zea mexicana capable of being harvested in multiple crops, are subjected to multiple cropping, wherein the forage grass triticale is sown in a range of September 15 to October 5, has a sowing rate of 8-10 kg / Mu, is harvested within 30-50 days after the triticale turns green in the next year, and has a stubble height of 5-10 cm; then, the zea mexicana is sown continuously, has a sowing rate of 0.8-1.0 kg / Mu, is harvested within 60-130 days after the zea mexicana germinates, and has the stubble height of not less than 6 cm, wherein the zea mexicana harvested within 60-100 days can be continuously harvested as a next crop every 30 days after regeneration. The invention makes full use of advantages of high quality of the triticale, high yield of the zea mexicana, and relatively balanced quality of all crops of the zea mexicana, not only utilizes winter fallow fields, but also can avoid the disadvantage of low quality of triticale caused by high temperature, and finally achieves the purpose of providing balanced and high quality gramineous forage grasses for cows.

Description
