Early blight  and  late blight  are important diseases on solanaceous vegetables.Although the names of the two diseases are only one word difference,some vegetable farmers do not know exactly about early blight and late blight.Some people even think that the two diseases are only happening time different. There are many problems in the prevention and treatment of diseases.Especially in the selection and use of chemical fungicide,blind drug use not only does not play a role in disease prevention,but delays the best prevention and control time,leading to serious diseases. early blight and late blight What’s difference between early blight and late blight? Early blight  mainly affects the stems,leaves,and fruits of vegetables,and is most susceptible to disease at the branches of leaves and stems.At the seedling stage,the base of the stem of the seedlings is dark brown lesions,slightly sunken,and has a ring pattern.The onset of adulthood generally develops from the lower lea

grape magnesium deficiency What’s symptom of grape magnesium deficiency?The leaves are chlorotic.Because magnesium can be transferred to young parts in plants,the top leaves are asymptomatic. Initially starting from the base blade,the leaf edge turns yellow first,the leaves are water-stained,and the yellow veins are severe. General reasons 1.The soil is mostly acidic,the pH value is too low,the magnesium leaching is serious,the release of magnesium is obviously inhibited,and the average content of exchangeable magnesium in the soil is lower than the critical level,and the magnesium deficiency is serious. 2.Grapes are potassium-producing crops,but excessive potassium inhibits the absorption of magnesium by the roots of the grapes and transports magnesium ions to the above-ground parts,causing magnesium deficiency. 3.Magnesium and calcium,ammonium ions also have antagonistic effects,therefore,the soil calcium content is too high or the application of calcium and nitrog

 There are some disease during watermelon plantation,especially in the old melon area where continuous cropping.Recently,many farmers have consulted about the problems related to watermelon disease.Here we sort out watermelon diseases identification and hope it is useful to everyone. Occurrence period : mainly harm unseeded and freshly emerged seedlings. Identification points : stem base rot, seedlings tripped, white hyphae when high humidity. Occurance period : whole growth period Identification point :1.leaf, brown spotted,slightly depressed,yellow external halo,unaffected by veins, perforated when dry. 2.Fruit,The lesion starts dark green and becomes dark brown,and cracks can occur.   Occurence period : late growth period Identification point : lesion becomes from light green to yellow, and then brown, restricted by veins, mildew when wet.   Occurence period :whole growth period Identification point : 1.Leaf, from the edge of the leaf, it starts as hot

The main measures to build soil crumb structure 1,Intensive cultivation,increase use of  Microbes fertilizer Intensive cultivation makes the topsoil loose.Although the formed granules are not water-stable,they also play a role in regulating soil porosity.The continuous application of organic fertilizer can promote the formation of water-stable aggregates,and the degree of agglomeration of aggregates is high,various pores are distributed reasonably,and soil and fertilizer can be maintained and improved. 2,Rational rotation Annual or perennial grasses or leguminous crops,which grow robustly and have developed strong root systems,can promote the formation of soil aggregates.Returning straw,planting green manure,crops and green manure rotation,and paddy crop rotation are all beneficial to the formation of soil crumb structure. 3,Reasonable irrigation,timely cultivation Flood irrigation can easily damage the soil structure,so that the soil is compacted,and timely

First of all,let us understand the soil structure. The soil is a porous system.It consists of solid,liquid and gas three-phase substances.The solid material in the soil includes both mineral and organic matter.The liquid part refers to the moisture of the soil,which is preserved and moved between the pores of the soil and is the most active part of the soil. The gas part refers to the air of the soil and it is filled with pores that are not occupied by moisture.The pores are divided into three types: large,medium,and small.Among them,the large pores are called gas-filled pores.Large pores should not be too much,water is easy to run off if too much,and the pore size of small pores is too small,which is not conducive to the breathability and rooting of plants. Medium pores are also called water-holding pores.The more midium pores are more suitable for the growth of crops.Just like our human skin,the better the water retention and air permeability,the healthier it is.

When it comes to drought prevention ,everyone thinks that they may need more watering.Now,there is a better way that we can use microbiological fertilizers like Bacillus mucilaginosus to prevent drought. The reason is that:Bacillus mucilaginosus is also called silicate bacteria,it has strong potassium-dissolving ability,which is selected from the roots of crops and produced by industrial fermentation with a specific medium.Through its life activities in the soil,it increases the supply of plant nutrient elements,stimulates crop growth,inhibits harmful microbial activity,and has a strong effect of increasing production.It is currently the most significant and widely recognized microbial agent. Bacillus mucilaginosus 1.Bacillus mucilaginosus can secrete plant growth regulators such as auxin and gibberellin,increase roots and make seedlings strong,and directly enhance drought resistance of plants. There are auxin substances and gibberellin substances in the bacteria and ferm
