Embodiment 1

[0092] The step of drip irrigation paddy rice under the film of the present invention is as follows:

[0093] 1. Seed preparation

[0094] Before sowing, the rice seeds must be awned, and the special small-scale awning machine is used for processing. The treatment time of each batch of seeds is 5 minutes to achieve a relatively ideal effect.

[0095] 2. Land preparation

[0096] Weeding during the whole growth period of drip irrigation under plastic film uses a combination of chemical and artificial weed control methods to remove weeds: generally, the soil is sealed 5 days before sowing, and 80g of mixed herbicide is sprayed per mu, and the dry-grown rice is drip-irrigated under plastic film. After 15 days after sowing, the first peak of weeds appeared, and at this time, 60 g of mixed herbicide was sprayed per mu. The specific types of pesticides used can be selected according to the types of local field weeds, and several pesticides can be mixed and eliminated twice. The s...

Embodiment 2

[0132] The step of drip irrigation paddy rice under the film of the present invention is as follows:

[0133] 1. Seed preparation

[0134] Before sowing, the rice seeds must be awned, and the special small awning machine is used for the treatment. The treatment time of each batch of seeds is 4 minutes to achieve a relatively ideal effect.

[0135] 2. Land preparation

[0136] Weeding during the whole growth period of drip irrigation under plastic film uses a combination of chemical and artificial weed control methods to remove weeds: generally, the soil is sealed 5 days before sowing, and 80g of mixed herbicide is sprayed per mu, and the dry-grown rice is drip-irrigated under plastic film. After 15 days after sowing, the first peak of weeds appeared, and at this time, 60 g of mixed herbicide was sprayed per mu.

Embodiment 3

[0172] The step of drip irrigation paddy rice under the film of the present invention is as follows:

[0173] 1. Seed preparation

[0174] Before sowing, the rice seeds must be awned, and a special small-scale awning machine is used for the treatment. The treatment time of each batch of seeds is 6 minutes to achieve a relatively ideal effect.

[0175] 2. Land preparation

[0176] Weeding during the whole growth period of drip irrigation under plastic film uses a combination of chemical and artificial weed control methods to remove weeds: generally, the soil is sealed 5 days before sowing, and 80g of mixed herbicide is sprayed per mu, and the dry-grown rice is drip-irrigated under plastic film. After 15 days after sowing, the first peak of weeds appeared, and at this time, 60 g of mixed herbicide was sprayed per mu.

Abstract

The invention provides a drip irrigation under plastic film method for rice cropping. The drip irrigation under plastic film method for the rice cropping comprises steps of seeds preparation, soil preparation, seeding, seedling management, irrigation management, fertilizer management, pest control and the like; the seedling density is 33.3 to 36 thousand holes per mu and 33.3 thousand holes per mu are optically selected; or the seedling density is 30.5 to 32.6 thousand holes per mu and 30.5 thousand holes per mu are optically selected. Previously used conventional film with the length of 105 cm to 145 cm and for Sinkiang cotton culture is low in soil utilization rate which results in being relative low in seedling density, difficult in adjusting the rice line spacing to increase the seedling density, low in ground covering rate and large in exposed ground area, and accordingly weeds are relatively more. The planting yield is relatively high through the wide film under the condition that other planting conditions are identical.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a method for cultivating rice by drip irrigation under mulch. Background technique [0002] Rice is an important food crop in my country. Traditionally, it is mainly planted in paddy fields flooded with water (the water layer in the field is 3-10cm). my country is one of the 13 water-poor countries in the world, and it is also a large agricultural country. Agricultural water accounts for 30% of the total water consumption 70-80%, especially in arid and semi-arid areas, agricultural water consumption reaches more than 90%, while the total water consumption of paddy fields accounts for more than 65% of agricultural water consumption. Due to changes in the global climate in recent years, spring droughts and summer droughts have occurred frequently, resulting in large-scale production reductions in northern rice planting areas, which seriously hit the enth...
