1. What are the current problems in the use of cake fat? Cake fat is a good source of organic fertilizer, and its application in production is relatively high. According to the author's survey in rural areas, farmers have insufficient understanding of the characteristics of cake fat and there is still the use of cake fat. Some problems are mainly manifested in the following two aspects. 1.1 is applied after maturity. Although the cake fertilizer is organic fertilizer, its carbon-nitrogen ratio (C/N) is relatively small, and it is rapidly decomposed after being applied to the soil and is a quick-acting organic fertilizer, so it can be directly applied.If it is soaked with river water, human waste, etc. After application, it will cause about 10% loss of nitrogen and about 20% loss of organic matter, although the fertilizer effect will be fast.1.2 It is used as a seed fertilizer.Some people like to use the cake fertilizer as a seed fertilizer and apply it around the seed. It is a more adventurous practice that cake fat is a hot fertilizer that produces high temperatures in the process of fermentation and decomposition, such as close contact with crops, which often causes burning of roots, affecting seed germination and seedling emergence.2. What should be taken into account when using the correct method? 2.1 Cake fat It can be used as a base fertilizer after being mixed with compost and manure, or it can be used as a top dressing alone.As a top dressing, it can be applied directly after the cake is fully crushed, and attention should be paid to maintaining a proper distance from the crop seedlings to prevent the seedlings from burning when the cake fertilizer decomposes and ferments. According to tests, it is proved that using cake fat as top dressing has a smooth and long-lasting fertilizer effect, and the effect is better than chemical fertilizer, and it has a long-lasting aftereffect. 2.2 When the cake fat is directly applied, it is easy to handle because of its own fragrance. Insect pests are introduced underground, so mix them with proper amount of pesticides for prevention.2.3 When the amount of cakes is limited, priority should be given to crops and cash crops for topdressing.
