Background

Rice is the most important grain for people in China. The method improves the yield of rice, enlarges the planting area of rice and is very important for guaranteeing the safety of grains. At present, the main planting mode of rice in China is mainly paddy field planting, conditions and technical methods in the planting process are complex, and requirements are low, so that the planting and the yield of the rice are affected, the expected requirements cannot be met, and the quality of the rice is affected. In order to solve the problem, it is important to develop a cultivation method of five-color rice.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a cultivation method of grid five-color rice so as to solve the problems.

In order to achieve the above purpose, the present invention adopts the following technical scheme: a cultivation method of five-color rice of a grid comprises the following steps:

1) Seed source selection: the method comprises the steps of cultivating and hybridizing the Wugongshan rice in Jiangxi province, pretreating seeds, including rice seed drying, rice seed screening, rice seed disinfection and seed dressing, and airing for 1-2 days;

2) Optionally: selecting sandy loam or loam with loose soil, good drainage, fertile soil and deep soil layer, and one borehole per 60 mu;

3) Rotary tillage: after wheat harvesting, the shorter and better the wheat stubble is when wheat is harvested, the rotary cultivator or the straw returning machine is selected for the first rotary cultivation according to the condition of the amount of grass in the land, and the depth of the first rotary cultivation land is 12-15 cm;

4) Applying a base fertilizer: the operation is carried out by a fertilizer spreader, the depth of the base fertilizer is 8-10 cm, and the spreading is uniform;

5) Secondary rotary tillage: the rotary tillage depth is 8 centimeters, so that the crushing degree of the straw is ensured, the straw is crushed thoroughly after two times of rotary tillage, and no straw stacking phenomenon exists;

6) Sowing: sowing by a rotary tillage drill with a row spacing of 20 centimeters, wherein the sowing depth is 2 centimeters, the local area is not more than 3 centimeters, the seed quantity is 15 jin/mu, and the sowing is uniform;

7) And (3) watering: the flood irrigation is needed for the first time, and watering is carried out within one day after sowing;

8) And (3) field management: maintaining the water flow in the paddy field and controlling the water surface to be 2cm-5cm away from the root of the seedling;

9) And (3) secondary watering: after the seedlings absorb water, the seedlings are irrigated for the second time to ensure that the water content is between 40 and 45 percent, the upland rice is not favored to be soaked in water for a long time, and the soil is kept moist, so that the sufficient water content is required to be ensured in the seedling stage, the tillering stage, the spike raising stage and the grouting stage;

10 Closed weeding: the weeding sealing liquid medicine is sprayed the next day after watering, the construction adopts a self-propelled or plant protection machine or an electric sprayer for operation, and the manual sprayer with small planting area can be used;

11 Pest control: the medicine is applied in three key medicine application periods of about 20 days of sowing, at the end of tillering and at the break period.

The beneficial effects of the invention are as follows: the five-color rice cultivated by the method has the advantages of about 132 days of growth period, 95 cm plant height, half-tightening spike, slightly short mango, good blackness, no red grain rice, strong disease resistance and lodging resistance, strong tillering force, 18.1 cm spike length, 93 grains per spike average, 30.5 g thousand grain weight and length-width ratio of 3:1, the yield is 79%, the mu yield is 400-500 kg, the taste is good, the quality is excellent, the operation in the cultivation process is convenient, the breeding work intensity is lightened, the breeding work efficiency is improved, and the method has important significance for accelerating the cultivation process of new varieties.

Detailed Description

In order to better understand the present invention, the following specific examples are used to describe the technical solution of the present invention in detail.

A cultivation method of five-color rice of a grid comprises the following steps:
