[I Love Yishizhuang] Using Yishizhuang Fertilizer to Grow Rape, Yielding More Rapeseeds with Ease

Oil is a major nutrient for human survival. Rapeseed oil is known as the "Olive Oil of the East", which shows its rich nutritional value. Rapeseed oil accounts for more than 55% of the output of domestic oil crops and is the largest source of domestic edible oil, playing a core role in safeguarding the national edible oil supply security strategy. The annual planting area of rape in China is about 110 million mu. Since rape planting does not compete for land with food crops and can be rotated reasonably, there is great room for development. Farmers can use the winter - fallow fields to grow a season of rape well. They can not only extract oil for their families to eat but also sell rapeseeds to obtain certain economic income. In order to further develop the rape production in China, the state has gathered many well - known experts from multiple disciplines in the rape field to form the "National Rape Industry Technology System" and jointly studied the simplified cultivation mode of rape. Among them, developing slow - release, full - nutrient, multi - functional special fertilizers for rape and promoting the one - time fertilization technology is the core technology of the entire technical system.

I. R & D Background of Yishizhuang Special Fertilizer for Rape

Fertilizer is the food of crops, and the amount of harvest depends on the fertilizer! How can we apply fertilizers well and grow rape to achieve high yields? Choosing a good fertilizer is crucial. In the early days of the founding of New China, we generally applied farmyard manure. Around the 1960s, with the popularization and application of three simple fertilizers, namely nitrogen, phosphorus, and potassium fertilizers, the nutrient supply of macronutrients for crops was gradually supplemented to a certain extent, and the yield was thus greatly increased. In the past two decades, with the popularization and application of ternary compound fertilizers, agricultural production has reached a new level. However, long - term application has led to a decline in soil organic matter, and medium - and micro - elements have not been supplemented, resulting in increasingly compact soil and more obvious nutrient - deficiency phenomena. In recent years, due to the shortage of rural surplus labor and the increasingly prominent trend of rural labor aging, farmers have a higher demand for labor - saving and time - saving fertilization. Therefore, fertilizers suitable for one - time application to manage the whole growth process of crops will surely be favored. Against this background, slow - release, full - nutrient, multi - functional special formula fertilizers for crops have emerged as the times require. Yishizhuang special fertilizer for rape is such a kind of "perfect fertilizer" that can not only meet the current traditional transplanting rape cultivation mode but also meet the requirements of farmers for simplified cultivation. It is a well - recognized good fertilizer among the people. Now, the research, development, and promotion of Yishizhuang special fertilizer for rape have passed the achievement acceptance of the national expert group and have become the core technology of the National Rape Industry Technology System. It is also a mature and supporting technology for high - yield, high - quality, and efficient rape production in China at present. Its formula has even obtained a national patent. An unprecedented revolution in rape fertilization is beginning...

II. Characteristics of Yishizhuang Special Fertilizer for Rape

Yishizhuang special fertilizer for rape was carefully developed over a period of five years by the team of Professor Lu Jianwei from Huazhong Agricultural University, a post scientist of the National Rape Industry Technology System, through large - scale soil - testing formula and combined with the nutrient absorption laws and characteristics of rape. Yishizhuang special fertilizer for rape has four prominent characteristics:

1.Balanced nutrients and reasonable ratio: It contains macronutrients (nitrogen, phosphorus, potassium), medium - elements (calcium, magnesium, sulfur), and micro - elements (boron, zinc, etc.) required for rape growth. The nutrients are comprehensive and balanced, and the ratio is scientific and reasonable, which can meet the nutrient needs of the whole growth period of rape, truly making up for what is lacking.

2.Slow - release and long - acting, promoting root growth and full seedlings: Yishizhuang special fertilizer for rape is added with a fertilizer slow - release agent, which is slow - release and long - acting, making the fertilizer effect sufficient in the early stage and stable in the later stage. It ensures that the rape blossoms and matures uniformly, with less harvest loss. It is convenient for both mechanical harvesting and manual harvesting, meeting the requirements of simplified production. This product contains humic acid and organic matter, which can effectively promote the root growth of rape, without burning seeds or seedlings. The emergence rate is high, and it is easy to achieve full seedlings in one sowing, with uniform, neat, and strong seedlings, laying a solid foundation for high - yield rape.

3.Cost - saving, efficiency - increasing, and soil - improving: The utilization rates of nitrogen, phosphorus, and potassium in Yishizhuang special fertilizer for rape are high, and all three elements exceed the domestic average level by more than 12%, greatly improving the comprehensive utilization rate of fertilizers, saving costs, increasing efficiency, and being economical and environmentally friendly. At the same time, it also contains a soil conditioner, which can effectively improve the physical and chemical properties of the soil and enhance soil fertility.

4.Labor - saving, time - saving, and significantly yield - increasing: One - time application of Yishizhuang special fertilizer for rape can guarantee the nutrients required for the whole growth period of rape. One - time application manages the whole process, saving labor and time without the need for top - dressing.

III. One - time Fertilization Technology of Yishizhuang Special Fertilizer for Rape

The one - time fertilization technology of Yishizhuang special fertilizer for rape is developed based on the growth and development characteristics of rape and the current planting mode, meeting the requirements of the current simplified cultivation of rape production. Then, how can we scientifically apply Yishizhuang special fertilizer for rape to meet the technical requirements of one - time application for the whole process?

1.For a standard mu (667 square meters), apply 40 - 50 kg of Yishizhuang 35% special fertilizer for rape, plus 10 - 30 kg of ammonium bicarbonate as base fertilizer, without the need for top - dressing.

2.For a standard mu (667 square meters), apply 40 - 50 kg of Yishizhuang 40% special fertilizer for rape as base fertilizer, without the need for top - dressing. When the planting density of transplanted rape or direct - sown rape is relatively sparse, an appropriate amount of ammonium bicarbonate should be added.

3.According to the differences in soil fertility and different previous crops, the application amounts of Yishizhuang special fertilizer for rape and ammonium bicarbonate can be appropriately increased or decreased.
