Embodiment 1

[0020] Example 1: Take 5 years as a cycle, design the width of the border to be 300 cm, and divide the serial number of vertical moisture in each plot into 1 to 15, with a vertical moisture width of 20 cm and a depth of 20 cm. Before the rice is harvested in the first year, intersow wheat (oil) seeds, and after the rice is harvested, three longitudinal rows A 1 , B 1 、C 1 , the rest of the ground is no-tillage, where A 1 , B 1 Buried rice straw, C 1 Make drainage and irrigation ditches, and the operation of the rest of the furrow is the same; in the same year, before the wheat (oil) is harvested, rice seeds are interplanted, and after the wheat (oil) is harvested, the wheat (oil) straw is buried in C 1 . From the second year to the fifth year, the vertical soil should be reopened after moving 1 / 5 of the width from the original vertical soil position to the same direction every year, respectively A 2 , B 2 、C 2 ...A 5 , B 5 、C 5 , the specifications are the same as a...

Embodiment 2

[0021] Embodiment two: take 4 years as a cycle, design furrow width 300cm, in every furrow, the vertical moisture division serial number is 1~12, vertical moisture wide 25cm, deep 20cm, before the rice harvest of the first year, intersow wheat (oil) kind , after the rice is harvested, open three vertical rows A at sequence numbers 4, 8, and 12 1 , B 1 、C 1 , the rest of the ground is no-tillage, where A 1 , B 1 Buried rice straw, C 1 Make drainage and irrigation ditches, and the operation of the rest of the furrow is the same; in the current year, before the wheat (oil) is harvested, rice seeds are interplanted, and after the wheat (oil) is harvested, the wheat (oil) straw is buried in C 1 . From the second year to the fourth year, every year from the original longitudinal soil position to the same direction, 1 / 4 of the width of the border is opened again, and the specifications are the same as above, respectively A 2 , B 2 、C 2 ...A 4 , B 4 、C 4 , the vertical soil...

Abstract

Disclosed is a highly effective and safe stalk utilizing method which includes, during the cycle of four or five years, digging longitudinal trenches in the field year by year in turn, after harvesting the rice each year, imbedding rice stalk into each two longitudinal trenches, using one of them as irrigation ditch, after harvesting wheat each year, imbedding wheat stalk into the original irrigation ditch, microbiological bacterium can be added into during imbedding the stalk.

Description

technical field [0001] The invention relates to a technology for returning crop straws to the field, in particular to an efficient and safe full-volume returning utilization method of rice, wheat and oil straws integrating no-tillage, rotational tillage and fallow. Background technique [0002] Rice straw is an important biological resource in the crop production system. It has a wide range of uses. After processing, it can be used as fertilizer, feed, fuel, industrial raw material and edible fungus base material. However, most scholars tend to return crop straws to the field for the purpose of soil and water conservation, ecological balance, environmental safety, and effective use of renewable resources, which are beneficial to the sustainable development of agriculture. According to incomplete statistics, the annual output of straw in the world is 2 billion tons, of which 600 million tons is produced in my country. However, due to incomplete utilization, farmers find it t...
