Soil covering, drought resisting and seedling conserving cultivation method for planting corns among spring bean stubble

Abstract

The invention discloses a soil covering, drought resisting and seedling conserving cultivation method for planting corns among spring bean stubble. The method includes the steps of A, removing the stubble, wherein the spring bean stubble is cleaned away, 120 cm wide furrow faces and 40 cm wide furrows are reserved, and 6-7 cm thick narrow rotary pillage or manual stubble removing is performed; B, establishing furrows, wherein the sowing furrows which are about 6 cm deep are transversely established on the furrow faces, and the row space is 40 cm; C, sowing seeds, wherein the seeds are evenly sown in the sowing furrows, and after seedlings are in full stand, the number of the seedlings in each mu of land is about 4500 to 5000 according to final singling; D, performing watering, wherein the sowing furrows are sufficiently watered through bottom water; E, covering the seeds, wherein the seeds are covered with thin soil the instant that there is no open water in the sowing furrows, and the thin soil on the core seeds is about 4 cm thick; F, performing soil covering, wherein the furrow faces are covered with thin soil so that watered soil cannot be seen on the sowing furrows of the furrow faces, and the thin soil on the corn seeds is about 5 cm thick; G, conserving the seedlings, wherein before or after the corn seedlings are in full stand, insects, hares, wild pigeons and the like are prevented from damaging the tender seedlings; H, preserving moisture, wherein after the seeds are sown, the furrow faces are covered with thin soil every other five days by principle, when it is proper to plough soil after raining, the furrow faces are covered with thin soil in time, moisture evaporation is reduced, the furrows faces are covered with thin soil about 4 times to 5 times within 20 days after the seeds are sown, and the furrows faces are covered with the thin soil which is about 0.8 cm thick at each time; I, performing management, wherein daily field management is performed.

Description

technical field [0001] The invention relates to a farming method for covering corn with soil to resist drought and protect seedlings, in particular to a cultivation method for planting corn with soil covering soil and protecting seedlings against drought in hilly and mountainous areas and dry plains in southern my country. Background technique [0002] Corn is an important food crop, and my country's sown area ranks third after rice and wheat. Corn can be divided into spring corn, summer corn and autumn corn according to the sowing period. Our country has a large population and little arable land, and grain production is an endless topic of research. In the case of exploring the current crop layout and planting system, increasing the multiple cropping index, expanding the planting area and output of corn, finding a suitable stubble layout, and creating a stable planting system are the prerequisites. The key is to support stable and high-yield farming technology, which is in...
