Effect of different ratio of fertilization on yield of Rice
The premature senescence of rice from heading to maturity will lead to poor grain filling, increase of blighted grain and decrease of yield. There are many factors leading to premature senescence in the later stage of rice growth. First, improper cultivation and management. The planting density is too high, the plant growth is weak; the early and middle stages of nitrogen fertilizer application, phosphorus and potassium fertilizer and trace element fertilizer application.

Ratio of cotton base fertilizer
The ratio of cotton base fertilizer (nitrogen, phosphorus and potassium fertilizer) is generally 1: 0.3: 1. According to the determination, the yield of 100 kg per mu of cotton needs to absorb 12 kg of nitrogen, 4 kg of phosphorus pentoxide and 12 kg of potassium oxide, which is 5-6 times that of cereal crops. In addition, some compost should be applied appropriately.

A New Formula for Fast growth and High yield of Pleurotus ostreatus
Tea mushroom, also known as tea tree mushroom, is a rare delicious health food, which sells well in the market. at present, the price of fresh mushroom is up to 20 yuan / kg. At present, the yield of artificial cultivation of Pleurotus ostreatus is low, which is mainly controlled by the strain and the formula of cultivation materials. The new formulations of several ideal cultivation materials are introduced as follows: 1. Tea shell powder 70%, rice bran 20%, tea meal powder 5%, sucrose 2%, lime 1%, gypsum 1%, potassium dihydrogen phosphate 1%. Take the dry material according to the formula ratio, the ratio of material to water is 1 ∶ 1.25, mix well.

Application proportion of Special Fertilizer in Cotton drip Irrigation Field
First, the total amount of cotton fertilizer input in high latitude sub-suitable cotton areas per unit yield of seed cotton 300-380 kg, the need to put 70-80 kg of natural fertilizer, equivalent to 160-180 kg of standard fertilizer. To achieve "jin fat cotton". If you put 1 kg of standard fertilizer, you can produce 1 kg of lint. 137 regiment soil test results and cotton plant nutrition diagnosis generally lack zinc, 1-2 kg zinc fertilizer is applied in autumn, and the yield is increased by 5% and 10%. For plots rich in potassium, the application of potash fertilizer is 5-10 kg, especially

Applying potassium to garlic has high yield and good quality.
Potassium is a necessary nutrient element for crop growth, and its effect on increasing crop yield and improving the quality of agricultural products has been confirmed in many crops, but there are few reports on the effect of potassium on the yield and quality of garlic. The soil and Fertilizer Institute of Zhejiang Academy of Agricultural Sciences has proved that the application of potassium to garlic has high yield and good quality through two years' field experiment. 1. The results of field experiment on the effect of potassium application on garlic for two years showed that the application of potassium fertilizer could significantly increase the yield of garlic. Under the condition of equal nitrogen and phosphorus level, the yield per mu of potassium fertilizer was 60.0 higher than that of non-potassium fertilizer.

California brome
California brome is a perennial, tufted forage with wide and long gray-green leaves and high leaf / stem ratio. The biggest morphological difference between California brome and awnless brome is that it has no underground rhizome. The soil requirement of California brome is similar to that of awnless brome, and its cold resistance is slightly worse than that of awnless brome, but its heat resistance is significantly shorter than that of awnless brome, and most varieties can be used for 6-8 years. California brome has a high leaf / stem ratio, its feeding quality is better than that of awnless brome, and its yield is similar to that of awnless brome. California brome is suitable for the east of China.
