Scientific and reasonable fertilization is beneficial to crop growth. What should I pay attention to when fertilizing ginger? Ginger is one of our most common condiments, and it is also one of the most commonly used medicinal and edible ingredients. Chinese medicine books record that ginger has the functions of dispelling cold and sweating, sterilizing and detoxifying, relieving cough and resolving phlegm, and regulating stomach. Ginger, also known as Bailayun, is an essential vegetable and condiment in the kitchen.

Farmers' friends grow ginger as a cash crop, which has become the main source of income and an indispensable new project to get rich. In order to improve the excellent yield of ginger planting, we should understand the demand law of ginger for fertilizer, integrate the growth cycle of ginger, and adopt reasonable fertilization to make the yield and quality of ginger go up a step.

1 What fertilizer is not suitable for ginger? Ginger should not be applied to unfertilized livestock manure, especially some farmyard manure rich in calories. It will have a great influence on the formation of ginger and lead to the ineffective growth of ginger. For example, pig manure is one of them. After pig manure is applied to the ground, it will generate heat in the soil and cause damage to the roots of ginger.

In the whole process of chicken farm, using caustic soda and other disinfection chemicals to disinfect chicken coops can eliminate pathogenic bacteria, but it can't fatten pig manure, and there are still pathogenic bacteria, larvae and harmful microbial strains in pig manure. After pig manure is taken out, it must be composted and fattened, and the pathogenic bacteria and larvae must be kept at a high temperature.

Some people think that ginger repels chlorine. Many friends think that ginger is a chlorine-expelling plant, but it is not. Sodium chloride is cheap and good. Proper application can improve the yield and quality of ginger. Too much chlorine will affect the formation of ginger starch and the quality of ginger. Chlorine is one of the nutrient elements and one of the essential elements for crop growth. If ginger is considered as a chlorine-resistant plant and is not used at all, it is very incorrect to use ammonium sulfate as base fertilizer completely, and the growth effect of ginger is not good.

It was found that the common dechlorinated compound fertilizer was used in the planting process of ginger, which contained a certain amount of chlorine. Compared with ginger planted with ammonium sulfate, it has better quality, higher yield and lower capital investment cost. The processing procedures of ammonium sulfate and potassium chloride are different, and the process flow of ammonium sulfate production and processing is relatively inconvenient, so sodium chloride needs to be much simpler, and the cost and price control will immediately cause the price of potassium sulfate to be higher than that of sodium chloride.

Ginger is a potassium-loving crop. In specific application, 75% ammonium sulfate can be mixed with 25% sodium chloride. The appearance design of this planted ginger is particularly beautiful and the yield is high.

If crops are to grow well, it is very important to lightly topdress and reapply base fertilizer. Under the condition of sufficient base fertilizer, it is easier to improve the yield of grain crops by auxiliary fertilization. Generally, 3~5 cubic meters of fully fermented organic fertilizer, bean cake 100 kg, ammonium sulfate 15 kg, sodium chloride 5 kg, fertilizer containing boron, zinc, magnesium and other nutrients 1 kg are applied per mu, or ginger organic compound fertilizer is adopted immediately.

When the ginger seedlings grow to about 25 cm, two small forks appear, which can properly fertilize the ginger seedlings and promote the healthy growth of Jiang Miao. 20kg diammonium phosphate per mu, or urea solution+potassium dihydrogen phosphate, is applied along the water, and the urea solution is not more than 5kg per mu, only 3kg. Potassium dihydrogen phosphate has high fertility, with an yield of about 2 kg per mu.

4 Grasping beginning of autumn Fat Ginger In the hot summer, it mainly grows the whole plant, and the underground stems grow slowly, entering the beginning of autumn solar term. The weather temperature is not so high, it is getting softer and softer. Ginger has gradually entered the road of rapid growth, which is also the key transitional stage of ginger.

Therefore, don't be stingy with fertilization this time, topdressing organic fertilizer and assisting in the application of chemical pesticides. The application of douchi per mu is about 100 kg, after full fertilization, 300 kg of dried chicken manure, 30 kg of diammonium phosphate, 0/7 kg of ammonium sulfate/kloc-0, and 8 kg of sodium chloride. After mixing these fertilizers, 65,438+05 plants were planted at intervals.

Usually at this time, ginger gradually enters the vigorous growth period, about 7 branches, and then enters the ginger expansion period. Therefore, in order to achieve the purpose of ginger fertilizer, apply fertilizer again to promote the expansion of ginger pieces. Some people call this fertilizer Zhuangjiang fertilizer. You can use a lot of elements, water-soluble fertilizer+soluble high-potassium fertilizer 5~6 kg per mu, and apply it along the river, but don't apply too much at a time. In a suitable environment in autumn, the later the harvest, the higher the yield.
