Seeing the diagnosis of seedlings is one of the main basis for the management of seedlings. It can be diagnosed according to the appearance of different growth stages of cotton using the following simple methods.

First, look at the height of the top blade

According to the physiological state of cotton growth and development, combined with production practices, people concluded that the relationship between the order of the leaves and the management of fertilizer and water. That is, from the top of the main stem, the number of four leaves from the top down can reflect the deficiency of fertilizer.

(1) Seedling period: normal 4321 (ie, the highest in the 4th leaf, followed by the 3rd and 2nd leaves, the lowest in the 1st leaf, the same below). Over-fertilization: 4 leaves less than 5 leaves; lack of fertilizer: 3421 or 3214;

(2) bud stage: normal (43) 21 (ie, the fourth leaf and the third leaf are basically equal, the height difference is less than 0.5 cm; the same below). Fertilizer: 4321; lack of fertilizer: 2134;

(3) Flowering period: Normal 3214 or (32)14 or (321)4. Over-fertilization: (43) 21; Lack of fat: 2314 or (21) 34.

Second, look at the ratio of red stems

That is, the percentage of stems in cotton seedlings is the percentage of total stems. When the fertilizer and water are normal, the ratio of red stems is: 50-60% at the seedling stage, 60-70% at the bud stage, 70-90% at the flowering bell stage, and the top should be kept at about 10 cm before the top of the flower. Red stem ratio is less than the above indicators, is the performance of excessive growth, red stem ratio is too large, the lack of fat and water.

Third, look at the leaf color

Rice color comparison card can be used to compare the color of the top 5th leaf. The normal leaf color is: Grade 2 to 2.5 after emergence, 3 to 3.5 levels before budding, 2.5 to 3 levels during budding, 3 levels at the beginning of flowering, 2.5 to 3 levels during full bloom, and 3.5 to 4 after blossoming. Grade, dropped to 3 levels at the beginning. If the leaf color is too dark, it will be too fat. If it is too light, it will be lack of fertilizer. However, it should be noted that the cotton green leaves with the application of chlormequat are not confused by the illusion but should be managed according to the specific conditions.
