How to select and prepare land for planting Polygonatum chinensis
Planting Huang Jing should choose shaded and humid mountains or relatively humid farmland, and the soil quality should be fertile sandy loam or light clayey soil. Using mountain planting, shrubs and weeds under the forest can be cleaned up in spring and autumn, turning and planing about 30cm, removing tree roots and other sundries, raking fine and leveling, making beds with the topography, waiting for sowing or planting. The use of farmland can be ploughed before planting, combined with ploughing 3000 kg of organic fertilizer per mu, after soil preparation to do bed reserve.

Greater Heat's mid-term management techniques for solar terms cotton production
To promote mainly, promote the combination of control, so as to control large seedlings, promote small seedlings, supplement weak seedlings, promote the transformation of weak seedlings, achieve balanced growth of strong seedlings, and set up high-yield shelves as soon as possible. Scientific fertilizer and water management is early and stable application of bud fertilizer. It is necessary to apply bud fertilizer to weak seedlings early, generally mastering the application of urea 5-7 kg per mu, cake fertilizer and phosphate fertilizer 25-50 kg each. Second, early and heavy application of flower and boll fertilizer. Generally at the end of early July, when there are 1 or 2 big peaches in the lower part of the cotton plant, topdressing is carried out and 15kg urea is applied per mu. The third is to apply top fertilizer.

The effect of fertilizer damage on cotton production is worrying.
In recent years, in the process of promoting new cotton varieties and technical services in cotton areas, we often encounter the problem of farmers' mistakes in applying fertilizer. First, when some cotton nutrition bowls are used to raise seedlings and prepare soil, too many farm fertilizers or chemical fertilizers are applied in the soil, so that some cotton seeds rot or die after sowing, and although some cotton seedlings emerge more evenly, they burn roots and die seedlings; second, after the emergence of cotton seedlings, excessive application of flushing fertilizer will burn and scorch all the two cotyledons of cotton seedlings; third, some cotton seedlings will be treated with base fertilizer before transplanting.

Management techniques in the Middle and later stage of Cotton growth
"Greater Heat" has passed, "the Beginning of Autumn" is coming. Cotton in southern Hebei has entered the peak period of blooming flowers and bolls, and the main problems at present are as follows: first, due to the excessive rainfall in the early stage, the lack of chemical control, the growth of some plots is prosperous, and the cotton plant is on the high side; second, due to the recent persistent high temperature, the occurrence of insect pests such as aphids and red spiders in some cotton fields is too heavy, which adversely affects the growth of cotton. At present, it is the flowering period of cotton, and it is also the key period for the management of cotton in the middle and later period. According to the climate characteristics of this year, we should seize the favorable opportunity, adjust measures to local conditions, classified guidance, and cut.

The situation of cotton production is not optimistic. Experts suggest management pay attention to four points.
The reporter learned from the working meeting of cotton production and high yield creation in the province on August 26 that the situation of cotton production in our province this year is not optimistic. In view of the current reality of cotton production, experts at the meeting suggested that cotton farmers grasp four measures. This year, cotton production in our province is characterized by a decrease in area, a decrease in per unit yield and a decrease in total yield. According to incomplete statistics, the actual harvest area of cotton in the province is about 11 million mu, more than one million mu less than the previous year, with an estimated cotton yield of 70,75kg and a total yield of 75-800000 tons, a decrease of 10%.

Misunderstandings in Cotton production and ways to increase production (5) (Plant Protection)
Over the past decade, with the popularization of transgenic insect-resistant cotton, cotton bollworm is no longer enough to make cotton farmers "talk about insect color change". However, Fusarium wilt and Verticillium wilt have always been a headache for cotton farmers. Aphids and red spiders make waves every year, and the occurrence of cotton bugs and Bemisia Tabaci has become more and more rampant in recent years. coupled with the sudden outbreak of cotton bollworm in a few years, cotton drug control is still an inevitable thing. At the same time, there are also two serious problems in the prevention and control of diseases and insect pests.

Limiting factors and Countermeasures of Cotton production (part two)
The phenomenon of premature senescence is mainly manifested as follows: first, after the peak boll setting period of cotton, the leaves lose green and yellowing, the etiolated leaves begin to develop from the farthest away from the main stem from top to bottom, from outside to inside, and the leaves gradually dry up and fall off. Second, in the later stage of cotton growth, the leaves turn red and lose the function of producing nutrients. The earlier the premature senescence of cotton appears, the more serious the yield reduction will be. The causes are as follows: first, the soil is barren and the soil fertility is insufficient. Soil nutrients can not meet the requirements of cotton growth and development; second, insufficient fertilization. Especially when potash fertilizer and nitrogen fertilizer are insufficient, some cotton farmers are afraid that when the amount of nitrogen application is large, they will make

Control techniques of soybean root rot in Heilongjiang Province
Root rot is common in soybean producing areas in Heilongjiang Province. the general diseased plant rate in the field is 30%-40%. The diseased plant rate in low-lying land and continuous cropping land is more than 70%, and the highest seedling death rate is more than 15%. The occurrence in the eastern region is more serious than that in the western region, and the occurrence is the most serious in the eastern soil moist area. In general years, the rate of diseased plants in the early growth stage (before flowering) of soybean is about 75%, the disease index is 35%-50%, and the disease index can reach more than 60% in rainy years. The incidence of soybean root rot mainly depends on the bacteria in the soil.

Soybean Fusarium mycorrhizal rot
Symptoms: Fusarium mycorrhizal rot is one of the common root rot diseases of soybean. It mainly occurs in the seedling stage. The root and stem basal therapy of the diseased plant produced oval brown strip to irregular concave spot, which expanded into a large patch around the main root, and some damaged the lateral root. The fungus is mainly harmful to the cortex, resulting in slow emergence of diseased seedlings, chlorosis of cotyledons, less lateral roots and fibrous roots, black roots in the later stage, epidermis rot, yellowing and dwarfing of diseased plants, early shedding of leaves under treatment, diseased plants generally do not wither and die, but few pods and small grains. Prevention and control measures should be taken to give priority to prevention. (1) choose anti-
