Benefits of technology

This patented method allows for more efficient use of heat and fertilizer resource while maximizing yields from smaller grains like olecranon pea or winter bean by growing them twice at different times during their entire life cycle. By doing it over several years on an agricultural plot containing both these types of plants together, we can achieve better returns than traditional methods that only produce single type of vegetable product.

Problems solved by technology

The technical problem addressed by this patented method is how efficiently convert excessive amounts of rice or corn into usable products while minimizing environmental impact caused by disposal methods such as burying them underground during storage periods when no product can be used again (the term refers to cold weather).

Embodiment 1

[0013] 3.1 Multiple cropping

[0014] The cropping system in which more than one crop (stubble) is continuously planted on the same piece of land in one year is also called multiple cropping.

[0015] 3.2 Rapeseed

[0016] It refers to the extremely early-maturing rapeseed with short growth period (65-70 days), rapid growth and development, weak vegetative growth, and small plant height (generally 60-80cm).

[0017] 3.3 One cooked irrigation area

[0018] Refers to the irrigated agricultural area where one crop is planted and harvested a year in the agricultural division.

[0019] 3.4 Harvesting with high stubble

[0020] Use a harvester or a sickle to harvest with high stubble, and the stubble height is about 20-30cm.

[0021] 3.5 Returning straw to field

[0022] Straw returning is a method of applying crop straws (such as wheat, corn straw, etc.) that are not suitable for direct feed into the soil directly or piled up and decomposed. It can improve soil properties, ac...

[0089] Planting test plan and test results

[0090] 1. Test plan and implementation description

[0091]The test was carried out continuously in Wuwei, Gansu for 4 years from 2009 to 2012. The test area is located at the eastern end of the Hexi Corridor, with an altitude of about 1531m, an average annual precipitation of about 160mm, an evaporation rate of 1919mm, a dryness of 5.85, and an annual average temperature of 7.8°C, ≥10°C The accumulated temperature is 2985°C. The annual frost-free period is 156 days, and the annual sunshine hours are 2945h. The soil of the experimental site is desert irrigated silt soil with medium fertility and irrigation conditions.

[0092] Taking different wheat stubble harvesting and straw returning methods as the experimental factors, a total of 4 treatment methods were set up, and the random block design was adopted, with 3 repetitions:

[0093] Treatment 1 (T1): Wheat was traditionally harvested with low stubble, leaving about 5 cm of stu...

Abstract

The invention discloses a production method for multiply cropping edible rape by harvesting and returning high wheat stubble straw to field. The method includes that wheat stubble of 25-30cm is harvested, and the edible rape is multiply cropped after the straw is smashed and returned to the field. By adopting the scheme, the Wuwei city is taken as a center to perform experiments and demonstration of multiple cropping the edible rape (precocial rape with a growth period of 60-70 days) by harvesting and returning high spring wheat stubble straw to the field, good results are obtained, light, heat and nutrient resources are fully utilized, and multiple cropping index and yield per unit area in the area are effectively improved. On the basis that the wheat yield is stably maintained at 400-500kg/mu, the average yield of multiple-cropping edible rape grains reaches 70-90kg/mu, single cropping a year is changed into double cropping a year, straw application remarkably increases content of organic matters and nutrients such as effective N, P and K in a farmland soil plowing layer, and evident economic and ecological benefits are obtained.
