experiment example 1

[0022] (1) Seedling raising: Sow good rice varieties with strong regeneration performance on April 1-5, adopt dry land seedling raising or two-stage seedling raising, strengthen water and fertilizer management and prevent diseases and insect pests in the seedbed stage, and cultivate multi-tiller and strong seedlings;

[0023] (2) Transplanting time and method: Transplant when the seedlings grow to 4-5 leaf age, adopt the method of pulling rope to dot fixed distance transplanting, every 667m 2 About 10,000 holes are planted, and the spacing between the seedlings is 23.3cm x 13.3cm;

[0024] (3) Management at full heading stage: before the full heading stage of rice, carry out water and fertilizer management according to conventional rice production. 2 Topdressing with urea 10kg; after the rice is fully eared, cut the upper part of the plant, leave a rice pile with a height of about 8cm in the field, and then fill the field with shallow water 2-3cm deep to promote the growth of ...

Abstract

The invention belongs to the technical field of agricultural planting, in particular to a rice feed and food dual-purpose culture method. Mainly, the upper portions of plants are cut off in the rice heading period to be processed into green hay or silage, left rice stems continue the tillering, normal growing and developing, heading and grain filling through a scientific water and fertilizer management method, and regenerated rice is obtained. The green hay and silage are rich in nutrient and high in palatability and solves the supply problem of high-quality feeds in the livestock breeding industry; meanwhile, the grain production is guaranteed by the culturing of the regenerated rice, and the obtained rice has the quality better than that of native rice.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a method for cultivating rice with both feed and grain. Background technique [0002] As one of the three major food crops in the world, rice is the most edible crop with the longest history in the world, and it is also one of the important food crops in China. According to relevant reports, China's rice production and consumption account for about 30% of the world. Rice planting is widely distributed in my country, and the perennial sown area is about 28.67 million hm 2 , the annual output of rice is about 180 million tons, accounting for 29% of the sown area of ​​grain and 40% of the total grain output respectively. With the continuous innovation of new variety breeding and cultivation technology, the rice yield per unit area in my country has gradually reached a new high, which has reached 16t / hm 2 , is going to 17t / hm 2 Forward, the total output reached 207 m...
