Embodiment 1

[0016] [Example 1] In 2004-2005, the test 11.5hm of interplanting rice (Changnongjing No. 3) with wheat (Yangmai No. 13) was carried out in Bazi Village, Licheng Town, Liyang City. 2 , on October 18, 2004, 8 days before the rice harvest, 120kg / hm of wheat seeds were sown 2 , one week after rice harvest, on the basis of adding organic fertilizer, apply imported compound fertilizer 375kg / hm 2 , Urea 150kg / hm 2 ; At this time, weeds 1-2 leaf stage, apply 600ml / hm 2 7.9% Puma plus 15g / hm 2 75% superstar, 600~750kg / hm 2 Spray the stems and leaves with water; on March 12, apply jointing fertilizer imported compound fertilizer 150kg / hm 2 And urea 150kg / hm 2 ;Apply sword leaf fertilizer once when the remaining wheat leaf age is 1, urea 75kg / hm 2 . The average actual output of the machine is 5160kg / hm 2 , an increase of 2164.5 yuan / hm 2 .

Embodiment 2

[0017] [Example 2] In 2005-2006, in Powei Village, Shanghuang Town, Liyang City, the test 8.3hm of rice (Changnongjing No. 3) interplanting wheat (Yangmai No. 13) was carried out 2 , 7 days before the rice harvest, that is, on October 20, 2005, 145kg / hm of wheat seeds were sown 2 , 7 days after rice harvest, on the basis of adding organic fertilizer, apply imported compound fertilizer 375kg / hm 2 , Urea 150kg / hm 2 ; At the same time, apply 600ml / hm 2 7.9% Puma plus 15g / hm 2 75% superstar, 600~750kg / hm 2 spraying treatment on stems and leaves; on March 13th, apply jointing fertilizer imported compound fertilizer 150kg / hm 2 , Urea 150kg / hm 2 ;Apply sword leaf fertilizer once when the remaining wheat leaf age is 1, urea 75kg / hm 2 . The average actual output of the machine is 6220kg / hm 2 , an increase of 2968.1 yuan / hm 2 .

Abstract

The invention relates to a process of wheat undersowing in rice field. It is characterized in that it comprises following steps: (1) sowing wheat into rice field with density of 112.5- 150 kg / hm2 7- 10 days before rice harvest; (2) dressing combination fertilizer and urine on base of organic fertilizer dressing 6-7 days after rice harvest, removing weed with pesticide; (3) dressing stem jointing fertilizer 138- 142 days after rice harvest; (4) dressing fertilizer for flag leaf when the leaf age is1; (5) harvesting wheat. The invention is characterized in that (1) sowing in advance for 7- 10 days, which release pressure of larbor force and reason; (2) it promotes wheat growth, and the weed removal effect is good; (3) the no-tillage cultivation is helpful to soil physical chemical properties and maintain soli cluster structure.

Description

Technical field [0001] The invention relates to a wheat cultivation technique, in particular to a cultivation technique for interplanting wheat with rice. Background technique [0002] Wheat is an important food crop in southern my country. In the long-term wheat production practice, the working people have accumulated various forms of wheat planting methods, mainly including plowing and sowing, direct seeding, drill sowing, etc. after rice harvesting. The performance is reduced, and it is time-consuming and labor-intensive, with low work efficiency and low and unstable wheat yield. In recent years, with the reform of production methods, the no-till sowing method of rice fields after rice harvesting has been developed, and the soil structure remains stable, saving a lot of time, machinery and labor consumed by plowing the land. However, these methods cannot effectively solve the contradictions of autumn sowing stubble, labor, and seasons. Contents of the invention [00...
