Cotton species avoid peeling peach blossoms.

according to the data detected by the seed management department, the germination rate of some cotton seeds in recent years is only about 60%, which is still far from the national standard of 80% germination rate. According to a large number of investigations, the reasons for the low germination rate of cotton seeds are as follows: first, harvesting unripe peeled peach blossoms; second, purchasing "human flowers" with large water content; third, mixing the diseased seeds of rotten cotton peaches; fourth, the cotton seeds are not fully dried and put into the warehouse; fifth, some broken cotton seeds are contained during processing; sixth, the residual acid content in coated cotton seeds is relatively high; seventh, the flowers are not strictly classified; and eighth, the proportion of autumn peach blossoms is high. Among the above factors, peach blossom peeling has become the main problem.

It is understood that the reason why farmers harvest and peel peach blossoms is that they are afraid of others stealing flowers in the field; second, they pick peaches during the day, and the whole family can help peel flowers at night; third, the moisture content of peach blossoms is higher, so they can sell more wet flowers, and sell more with less.

The increase in the proportion of peach blossom stripping has formed a major public hazard to cotton seed quality and fiber quality. According to the scientific research department test, the germination rate of fully ripe cotton seeds is 95.5%, the germination rate of mature cotton seeds is 92%, the germination rate of semi-mature cotton seeds is 63%, and the germination rate of immature cotton seeds is only 14%. At the same time, the fiber grade, length, strength, number of turns and other quality indexes of peeled peach blossoms decreased greatly compared with mature cotton. Therefore, it is necessary to reject the peach blossom peeling outside the flower purchase.

The quality of cotton seed is related to the overall situation of cotton production. Selecting and using good quality cotton seed can lay a good foundation for high yield of cotton. In order to improve the quality of flower collection, according to years of experience, the following measures should be taken.

1. Formulate policies for superior seeds and flowers at superior prices, increase the gold content of superior seeds and flowers, and use superior prices to mobilize farmers 'enthusiasm for selling superior flowers.

Second, reject the "human flower" and peel peach blossoms for planting flowers. The flowers should be mature flowers with more than 5 days of opening. The water content of seed flower should not exceed 12%, and that of cotton seed should be controlled at about 11%.

Third, advocate curtain frame drying flowers, not on the ground drying flowers, not on the concrete floor directly drying flowers, in case of dumb.

4. flower harvesting should be strictly graded, and dry flower seeds should be stored. before october 20, substandard flowers and autumn flowers can only be purchased as commercial flowers, and must not be used as planting flowers.

Fifth, select cotton seeds, process coating, eliminate inferior cotton seeds.
