Embodiment 1

[0021] This embodiment provides a method for in-situ return of high-stalk crop straws to the field for soil fertilization, which specifically includes the following steps:

[0022] Step 1: Level the field, ditch and ridge, and plant high-stalk crops on the ridge;

[0023] Step 2: The high-stalk crops enter the mature stage, the lower withered and aged leaves are removed, and leguminous crops are interplanted between the two crops;

[0024] Step 3: when the crops with high stalks on the ridge are harvested, keep the stalks in situ;

[0025] Step 4: After harvesting the pods of leguminous crops on the ridge, uproot the remaining tall stalks and return them to the field together with the vines and leaves of leguminous crops;

[0026] Step 5: The soil on the ridge is transferred to the furrow, and the tall stems and vine leaves of leguminous crops that are mixed and returned to the field are covered.

[0027] In the above method, in step 1, the ridging specification and planting...

Embodiment 2

[0033] This embodiment provides a method for in-situ returning soil of high-stalk crop straw to the field for fertilization, including the following steps:

[0034] (1) Planting high-stalk crops is flue-cured tobacco, the plant height of the tobacco plant is 130-150cm, and the cultivation method is ridge planting and pond planting; A flue-cured tobacco transplanting pond with a mouth diameter of 10cm and a depth of 20cm.

[0035] (2) 80-90 days after the flue-cured tobacco is transplanted, the growth of the flue-cured tobacco enters the mature stage, and the flue-cured tobacco leaves are harvested from the bottom up. After the lower tobacco leaves are harvested, sweet snap peas are interplanted between the two tobacco plants. The spacing is 8-10cm, the sowing rate is 3-4 grains / hole, and the seed is covered with soil after watering thoroughly, with a thickness of 2-3cm.

[0036] (3) After the flue-cured tobacco leaves are harvested and roasted, the stems of the tobacco plants...

Abstract

The invention provides a high-stalk crop straw in-situ utilization and in-situ field returning soil fertilizing method. The high-stalk crop straw in-situ utilization and in-situ field returning soil fertilizing method specifically comprises the following steps that step 1, a field is leveled, ditching and ridging are carried out, and high-stalk crops are planted on ridges; step 2, high-stalk crops enter the mature period, withered and aged leaves on the lower parts are removed, and leguminous crops are interplanted between the two crops; step 3, when the high-stalk crops on the ridges are harvested, stalks are reserved in situ; step 4, after the leguminous crop pods on the ridges are harvested, the reserved high stalks are pulled up along with the roots, and the high stalks and the leguminous crop vines and leaves are returned to the field on the spot; and step 5, soil on the ridges is transferred into the ditches, and the high stalks and leguminous crop vines and leaves which are mixed and returned to the field are covered. By means of a certain cultivation method, straw in-situ utilization and field returning of the high-stalk crops are achieved, labor operation is reduced, the straw field returning difficulty is lowered, and straw resource utilization and soil fertilization can be achieved.

Description

technical field [0001] The invention belongs to the technical field of soil fertilization by returning straws to fields, and in particular relates to a method for returning straws of high-stalk crops to fields in situ. Background technique [0002] High stalk crops refer to crops with high stalks, such as corn and flue-cured tobacco. After the high-stalk crops grow into the mature stage, the moisture content of the straw is low, and the degree of fibrosis and lignification is high, which leads to the difficulty and high cost of harvesting, crushing, and feed treatment of the straw. Farmers mostly incinerate the next crops, which not only wastes resources, but also seriously affects air quality. [0003] At present, crop straw returning to the field generally involves crushing the straw and throwing it on the ground, and turning the crushed straw into the soil by plowing or rotary tillage. The straw of high-stalk crops has low water content, high lignin content, and incompl...
