Seeds do not germinate or have longer germinate times because of the slow absorption of moisture by seeds. In addition, there is a low budding rate of the plume seed. In addition, styrofoam seeds are given stricter requirements for moisture and temperature during the gestation process. If seeds are planted during high-temperature seasons, they do not germinate without treatment. Therefore, seeds should be treated for planting during the high-temperature season, i. E. Dry seeds should be planted before they are planted, then the seeds should be separated with a light hand and then immersed in water at about 20°c for 20 minutes. - 24 hours, wash, dry water and wrap it in a wet gauze so that it germinates in the 21 c environment and washes it once a day with water。
The saplings of the saplings are associated with root damage during planting, high soil moisture, fertilizer damage and root disease, mainly during periods of slow seeding. Vegetation and yellowing of real leaves are mainly caused by viruses and diseases, which can easily occur in the early stages of plant deceleration to the expansion of the tubing. The main reasons are as follows:
The plume is a straight root system, and the roots are weaker. The congested and long seedlings at the borders of the seedlings, low soil and root damage during planting, combined with the extent of soil moisture in the fields and climatic factors leading to the growth of the roots and the creation of conditions for disease infestation leading to the death of the seedlings. The use of 128 holes of cavepads or nutrients in production should be promoted, along with the use of grass-grass and frogstones as a matrix, the incorporation of microbicides, such as polybacterium, and the prevention of cystal bacteria. This method of seeding can be effective in avoiding the death of seedlings caused by thinness, injury to roots, long periods of slow seeding, and heavy soil moisture。
Uncompletely decomposed or applied fertilizers are too large to be watered in a timely manner, leading to fertilizer damage. First, fully decomposed organic fertilizers, deep tillage and dredges should be applied. In addition, ivory should be used in planting. Cultivation should be timely. Not too much fat. Water 2-3 eliminates fat。
Roots of decomposition are prone to death and decomposition during seed age. Pathogens are mainly infected with root causes to infect them. The disease is exacerbated by lower soil temperatures, higher humidity, heavier weights and the use of unsophisticated organic fertilizers. They can be used for drug blending, hot soup impregnation, high caps, prevention of pollution through the use of non-publicly hazardous fertilizers and the reduction of damage to root systems。
Mainly due to the plant virus, the plume fragrance is dwarfed, heartleaf curls and yellow hair. High temperatures, drought, crab infestation and unscientific agricultural practices can lead to plant infections. The plume has to be treated in an integrated manner。
Early extraction refers to the phenomenon of extraction before the splint fully swells. The plume is mainly fed by larger plumes. When early extraction occurs, plants will age rapidly and the tubers will become fibre-shaped and lose their commercial value. Early extraction of ginger from the aroma takes place mainly in the spring open-air cultivation (may-june), for the following reasons and preventive measures:
Premature seeding times, excessive seedlings, long seeding times and low temperatures (around 4 c) can easily pass through springing stages, such as adjusting planting dates, low-temperature plantings, and relatively stable post-plant temperatures, and therefore no early extraction problems. Cultivation in the northern spring usually takes place at the end of february and at the beginning of this month, which avoids early production of sorghum。
Long daylights and high temperatures are the main cause of the squirms. One month of planting can easily impregnate plants and extract them, and the planting dates must be adjusted in a timely manner and delayed until june, with sunscreens and short-term sun-light treatment. In autumn and winter, seedlings can be 50d from seeding to seeding, and pre-treatment of real leaves with 12 slices can boost the expansion of the tubers and prevent the early extraction of seedlings。
The need for water was particularly acute at the beginning of the spring planting of the plume. At this time, the soil is dry, the ambient temperature is high and the air moisture is low. In addition, a long-term solar induction will promote the transformation of plants from nutritional to reproductive growth, which may lead to a stop to swelling of the tubers and to early stinging。
Precautionary measures: first, maintaining a reasonable standard of water quality in the field over the long life of the plant, especially in the early stages of the expansion of the tubing (smuggling). 30 cm from left to right) water and fast-activated nitrogen fertilizers to promote rapid expansion of the tub; combined urea or potassium phosphate solution can increase leaf cover nutrition and improve air moisture in growing fields。
In the production of the plume, the plumes usually look small, there are yellow scales outside and the quality is declining. The reasons are as follows:
The fragrance likes fertile soil. If the soil is not fertilized during the masonry period and does not meet the demand for fertilizers, the plume will slow down, the mast will be smaller at harvest and the monolithic will be reduced. It would therefore be preferable to choose fertile land for drainage and irrigation in good condition and to fertilize the formula to lay the foundation for high productivity。
The light has a significant impact on the nutrient accumulation and expansion of the plume. If cultivation is too intensive, it will reduce the accumulation of plant photocoding. Light bulb expansion is limited and light bulbs are small. This is most evident in winter greenhouse cultivation. In production, 55,000-5,500 plants are protected in winter and spring from 3,500 to 4,000 plants。
The requirements for environmental moisture, temperature, nutrients, etc. Are relatively strict and phased in the production of plume, e. G., long-term seedlings after planting, lower ambient temperatures when the plume expands, interruptions in production and harvest delays. As a result, light bulbs were reduced and their quality decreased. Therefore, after planting, do not spend more than 10 d of time crouching, from the expansion of the tub to the pre-harvest period, a small amount of water is used to keep the fields wet and dry, and it is damp for the first time in the 7-8 kamenaki plant
Time to catch fat, 3 times after 2 fats of 10d? Protection of seeding for winter and spring, cooling of ventilation, control of the temperature of the tubing at 15-20 °c,

Early extraction refers to the extraction of raw aluminum before the spas are fully swelled. The plume is fed mainly by larger saps. When early extraction occurs, plants will age rapidly and the tubers will become fibre-shaped and lose their commercial value. Early extraction of thorium from the aroma takes place mainly in open spring cultivation (may-june), for the following reasons and preventive measures:
Premature seeding times, excessive seedlings, long seeding times and low temperatures (around 4 c) can easily pass through springing stages, such as adjusting planting dates, low-temperature plantings, and relatively stable post-plant temperatures, and therefore no early extraction problems. Ginger. Cultivation in the northern spring usually takes place at the end of february and at the beginning of this month, which avoids early production of sorghum。

The light has a significant impact on the nutrient accumulation and expansion of the plume. If cultivation is too intensive, it will reduce the accumulation of plant photocoding. The tuber's fragrance is restricted and the light bulbs are small. This is most evident in winter greenhouse cultivation. In the production of 667 n, spring and autumn 5,000-5,500 plants are protected in winter and spring 3,500-4,000 plants。
The requirements for environmental moisture, temperature, nutrients, etc. Are relatively strict and phased in the production of plume, e. G., long-term seedlings after planting, lower ambient temperatures when the plume expands, interruptions in production and harvest delays. As a result, light bulbs were reduced and their quality decreased. Therefore, planting should not exceed 10 d of the time spent crouching, with a small amount of water being used to keep the field wet and dry until harvest, and a first time to catch fat in plants 7-8, and 3 times to fattening 667 m2, urea 5-7 kg after 2 fats 10d. The winter spring festival protected seeding, with ventilation cooling, the temperature of the plume being kept at 15-20°c, and when the outside plume of the plume was white or light yellow, the plume stopped swelling and harvested in time。
