Leaf age mode cotton culture method

Abstract

The invention discloses a leaf age mode cotton culture method which comprises the following steps: from Great Snow to Waking of Insects, frozen soil is upturned in winter and is then mellowed, and nutrition pot soil is fertilized; from Waking of Insects to Pure Brightness, seeds are planted, and seedlings emerge on Pure Brightness; from Pure Brightness to Grain Rain, the seedlings of cotton seeds emerge and grow to a plant with three leaves and one core to form sound seedlings for transplanting; from Beginning of Summer to Lesser Fullness of Grain, the transplanted cotton seedlings grow to a cotton plant with sever leaves; from Grain in Beard to Summer Solstice, the cotton plant starts to relay when growing seven leaves, starts to bud when growing eight leaves, starts to vigorously grow when growing ten leaves and starts to bloom when growing 17 leaves; from Lesser Heat to Great Heat, the main stem of the cotton plant grows 17 leaves, the first bud on the first fruit branch blooms and grows bolls, and then the cotton plant gradually enters the reproductive growth phase; and from Beginning of Autumn to Cold Dew, the cotton plant enters the picking phase from the reproductive growth phase. By using the ectal leaf age as the parameter, the invention realizes the accurate and quantitive application of seeding, fertilization, control and regulation on diseases and pests and other technical measures based on the growth phase of leaves. Thus, the method can be easily mastered by cotton planters and is convenient to carry out.

Description

technical field

[0001] The invention relates to a cotton cultivation method, in particular to a cotton leaf age pattern cultivation method. Background technique

[0002] In the practice of cotton production, how to accurately guide cotton farmers to control the crazy growth of cotton, and how to build a high-yield frame and steadily apply flower and boll fertilizers, so as to achieve high-yield and high-quality goals is a major issue in cotton production. For a long time, the vast number of cotton farmers can only use traditional experience to plant extensively. The entire cultivation process is in a state of aimlessness, and measures such as fertilizer and water management, disease and insect control, and chemical regulation cannot be accurately implemented.
