1. Improper distribution of organic nutrients blindly increase the fertilization amount in the base fertilizer and flowering period, increase the number, amount, and type of foliar spraying, resulting in excess nutrients, resulting in excessive growth of cotton, increased and thickened leaves, and increased photosynthesis. , Plants are long, forming a vegetative growth prosperous growth, and nutrient supply of boll bells, resulting in the lack of nourishment and loss of budding bell.
2. Insufficient supply of organic nutrients for long-term continuous production in cotton fields, less organic fertilizer input, lower soil organic matter content, blindly reduced fertilizer input to reduce costs, resulting in thin and dwarf growth of cotton plants, excessive nutrient growth, and decreased photosynthesis. Nourishment can not meet the needs of the growth of the bolls, causing the bolls to fall off.
3. Lack of mineral elements Lack of trace elements can cause the shedding of the bells. Nitrogen and zinc are essential elements for growth. Nitrogen deficiency and zinc affect the synthesis of auxin and lead to shedding. Calcium is an important component of calcium pectate in the intercalating layer. The lack of calcium causes the release of the bells. Boron deficiency can cause pollen abortion, resulting in infertility and loss.
4. Water deficiency or oversaturation 1 Drought soil drought, resulting in root hair death, accelerated plant water imbalance, resulting in decreased photosynthesis, mineral elements in the plant body is blocked, promote the synthesis of abscisic acid and ethephon in the plant, resulting in the loss of Lei Ling bell. Atmospheric drought, resulting in dry branches and stigma, reducing pollen viability, poor fertilization or infertility, resulting in the loss of Lei Ling.
2 The blister cotton field adopts furrow irrigation method, which forms water due to uneven terrain or man-made reasons. In case of continuous rain, the roots of cotton have become dark and the color of the leaves has turned yellow, the photosynthesis has declined, and malnutrition has caused the loss of the bell.
3 Humidity is too high In the flowering and bolling period of cotton, if the relative humidity is high, the anther cannot crack, and the anther water will swell and rupture and lose the ability to insemination.
5. Chilling injury caused the leaves to lack green and white, and even the top dry and buds, resulting in inhibition of chlorophyll synthesis, weakened absorption function, imbalance of water in the body, resulting in obstruction of the fertility process, resulting in budding wilting and dryness.
6. Salinization Due to salinization in cotton fields, cotton plants grow slowly, grow less, and have small, dark green leaves. Due to the toxicity of salt and alkali ions, the synthesis of chlorophyll is destroyed, affecting the formation of buds and the appearance of budding bells.
7. The hail hail has a short period of time, a fierce attack, a rapid attack, and a high degree of crackdown. This directly results in the loss of the bells and even the loss of the bell.
8. Strong winds and winds caused the cotton plants to rub against each other and cause the bells to fall off.
9. Poor fertilization temperature is too high or too low, humidity is too high or too low, lack of boron, can easily lead to poor fertilization or lack of development and shedding.
10. The density is too high due to the high rate of the two strains, the density is too large, the group is covered in shade, the light transmission is poor, and the photosynthesis is weakened, which easily increases the shedding of the bells.
11. The thin and weak cotton plants of cotton have poor resistance to the harsh environment, and they have weak ability to produce organic nutrients and cannot meet the needs of growth and development.
12. Soil compaction Soil compaction, poor permeability, affecting cotton root growth and microbial activity, slow nutrient release, weak fertility, resulting in the shedding of budding bells.
13. Mechanical Collision Due to many times of field operations such as cultivating, fertilizing, chemical modification, and pest control in the field, the machine directly knocks or knocks out the bell.
14. Weeds damage a large number of weeds and cotton plants to compete for water, compete for fertilizer, and win light, resulting in depressing cotton fields, light weakening, photosynthetic capacity decline, causing Lei Ling bell off.
15. Diseases and insects damage Harm of cotton aphid, blind aphid, and cotton bollworm directly cause the loss of the bell. Aphids, cotton leafhoppers, verticillium wilt, and blight frequently cause the cotton leaves to curl, yellow, and fall, reduce the leaf area, reduce the photosynthetic capacity, reduce the production of organic nutrients, and cause shedding.
Second, preventive measures
1. Aggregation of multiple breeding objectives, breeding new varieties, gradually broadening germplasm resources, enriching germplasm gene pools, using biotechnology and conventional breeding techniques to combine multiple breeding objectives, and focusing on excellent, early maturing, high yield traits Increased to a high anti-blight, insect-resistant, low-temperature synchronous improvement goals, to breed new varieties.
2. Replacement varieties The varieties with strong disease resistance and strong resistance are selected. For the cotton fields with severe blight and verticillium wilt, varieties with resistance (resistance) and verticillium wilt should be planted.
3. Promote water-saving irrigation technology to promote water-saving irrigation technology, effectively improve the utilization of water resources, to avoid drought, waterlogging in cotton fields, maintain the appropriate humidity in cotton fields, promote the normal growth and development of cotton plants, thereby reducing the shedding of the bell.
4.Scientific fertilization, fertilization, soil testing, formula fertilization, popularization of straw return, once applied oil slag and organic fertilizer, rotation for crop rotation, cultivation of green manure, adherence to the combination of organic manure and chemical fertilizer, combined use of land and land, and fertility , increase soil permeability, improve the consolidation of soil, and continuously improve soil fertility, provide abundant mineral elements for cotton growth, to meet the needs of cotton growth and development.
5. Proper and close planting and close planting can coordinate the relationship between vegetative growth and reproductive growth, population and individual, and establish a reasonable group structure, ventilation and light, making full use of light.
6. Improve the saline-alkali soil to lower the water level, wash the salt, grow green manure, increase organic manure, implement straw return, plant windbreak forest, and form farmland forest network.
7. Reduce operational levels Use water-saving irrigation techniques, chemical removal technologies, and biological control technologies to reduce the number of operations.
8. Integrated Pest Prevention and Control The principle of “prevention first, comprehensive prevention and control†is adhered to. The combination of biological control, agricultural prevention, and chemical defense shall establish a pest monitoring and forecasting system, strengthen forecasting and forecasting, protect natural enemies, and reduce the impact of pests and diseases on the budding bell.
9. Application of monitoring and rocket flood control technology to establish an automatic monitoring station for agricultural meteorology, provide meteorological data with accuracy and provide services for agricultural production in advance. The use of catalysts and rocket anti-cockroach technology to prevent hail on different heights of hail clouds, this technology has a clear catalytic effect on the cloud, flood prevention and disaster reduction significantly.
