Sowing high-yield cultivation method for wheat in arid land

Abstract

The invention discloses a sowing high-yield cultivation method for wheat in arid land and belongs to the technical field of cultivation of food crops in the arid land. The sowing high-yield cultivation technical method for the wheat in the arid land includes the following steps: a plowing layer is deepened through deep plowing, and accumulation of rainfall is increased; all applied fertilizer serves as base fertilizer by being combined with the deep plowing and is applied into soil deeply; after soil preparation, ridges are not formed, and flat-planting is conducted with equal line spacing. The sowing high-yield cultivation method for the wheat in the arid land is suitable for Shandong province and Huang-Huai-Hai winter wheat dry farming areas. The yield-increasing potential of the wheat in the arid land can be fully exploited, and the fertilizer and water utilization efficiency is improved. The cost is lowered, and the land output is increased. The agricultural water is saved, and the yield of the wheat in the arid land is improved. Good economic benefits, social benefits and ecological benefits are generated. In June 2012, experts from units such as China Agricultural University and the provincial agricultural technology extension master station conduct yield prediction and acceptance check to arid land wheat high-yield demonstration fields of the sowing high-yield cultivation method. As is shown by on-site repeating survey by the experts, the average yield per mu of ten mu of high-yield tackling fields achieves 703.5 kilograms, and therefore a new record for the average yield per mu of the wheat in the arid land in the country is set.

Description

technical field

[0001] The invention relates to the cultivation technology of grain crops in dry land, belongs to the field of agricultural technology, and specifically refers to a high-yield cultivation technology of wheat sowing in dry land. Background technique

[0002] Dryland wheat refers to the cultivation of wheat in arid and semi-arid areas relying on natural precipitation. In such areas, there is little precipitation during the whole growth period of wheat and lack of irrigation conditions. The growth of wheat depends entirely on natural precipitation. The level of its yield is closely related to the amount of precipitation in the growing year and the timing of precipitation. China's dryland wheat is mainly distributed in the western part of Northeast China, the northern part of North China, the Northwest, Inner Mongolia and the Qinghai-Tibet Plateau. The precipitation in these areas during the whole growth period of wheat is 150-250 mm. If the corresponding farmin...
