The invention effectively solves the problem of excessive fertilizer input caused by too frequent fertilization in the vegetative growth period of wheat, can keep the yield slightly increased under the condition that the fertilizer dosage is reduced by 24.3-31.2%, and obviously improves the recovery rate of nitrogen fertilizer, the agricultural efficiency, the partial productivity and the planting benefit.
Description
Technical Field
The invention relates to the technical field of fertilizers and fertilizers, in particular to a wheat base fertilizer free of additional tillering and striking root and an application method thereof.
Background
Wheat is an important food crop in China, and the whole growth period comprises 3 periods, wherein the vegetative growth period is from sowing and seedling emergence to jointing, the vegetative growth and reproductive growth parallel period is from jointing to heading, and the reproductive growth period is from heading to maturity. The vegetative growth period of wheat is about three months (generally from late 11 months to middle and late 2 months of the next year), but the overwintering period (about 2 months) when the growth is basically in a standstill is removed, and the time for meeting the growth conditions of wheat and the fertilizer to act in the vegetative growth period is only about 1 month. In this period, besides the base fertilizer, farmers also apply the tillering fertilizer and the striking root fertilizer in turn, namely the wheat is applied 3 times in the vegetative growth period, and the interval time of each application is only about 10 days. Research shows that although increasing the fertilization times under the same fertilization amount is beneficial to improving the fertilizer effect, the fertilizer dosage in the actual production always increases rapidly along with the increase of the fertilization times and becomes a main factor of excessive wheat fertilizer input[1](ii) a Meanwhile, the additional fertilization is difficult to mechanically operate, and the fertilization labor cost is increased due to frequent fertilization; more importantly, due to the hysteresis effect of the fertilizer efficiency after the fertilizer is applied to the soil, the frequent fertilization in the period is easy to cause fertilizer loss and waste, and the fertilizer efficiency is reduced.
At present, a solution to the above problems is to apply a slow/controlled release fertilizer as a base fertilizer at one time. The one-time fertilization has a plurality of stable yields due to the outstanding labor-saving characteristic,Increase in yield has been reported and related patent publications have been published[2]. The basic principle of one-time fertilizer application is to produce a controlled-release controlled fertilizer by means of coating and the like, so that the nutrient release of the controlled-release controlled fertilizer is synchronous with the regulation of the nutrient requirement of crops. The wheat has 2 nutrient absorption peaks after seedling emergence, namely, about 35 to 45 percent of nutrients (mainly provided by base fertilizer, tillering fertilizer and striking root fertilizer) are absorbed in the vegetative growth period, and the nutrient absorption peak is a nutrient absorption critical period; secondly, in the period of jointing and booting, the nutrient (mainly provided by jointing fertilizer) which accounts for about 40-45% of the whole growth period is absorbed in the period of jointing and booting, and the period of maximum efficiency of nutrient absorption is the period of maximum nutrient absorption[3]. Because of the influence of different regional climates and soil properties, the nutrient release of the slow-release and controlled-release fertilizer is often not matched with the nutrient requirement rule of crops, particularly, the growth period of wheat is long, the soil temperature change is large, the nutrient is easy to lose fertilizer and senilis in the maximum efficiency period, and the effect of one-time fertilization is not stable[4-5]And has fresh application in production due to higher fertilizer price[6]。
Therefore, aiming at excessive fertilizer input and waste, increased labor cost, instability of one-time fertilization effect and higher fertilizer cost caused by multiple fertilization in the vegetative growth period of wheat, and meeting the needs of farmers for simplified and low-cost technologies, the performance and application method of the existing base fertilizer are urgently needed to be improved, so that the fertilizer requirement rule of wheat is met to meet the nutrient requirements of wheat in the key growth period and the fertilizer efficiency and planting benefit are improved on the premise of reducing fertilization times and fertilizer consumption and saving labor cost.
