Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific examples.

[0033] A method for direct-seeding rice planting suitable for coastal lake-type silty sandy saline-alkali land, comprising the following steps:

[0034] Step 1. Plowing, soaking in water to wash salt and reduce alkali

[0035] The salt content of the coastal severely saline-alkali soil is as high as 20‰, and plowing is required before rice planting, the depth of rotary tillage is 15cm, and high-quality fresh water (below 3‰) is soaked in the field to wash the salt and reduce the alkali. (The effect of salt washing is determined) Salt washing and alkali reduction can reduce the salinity of the surface soil to 3‰, which can basically meet the growth needs of rice seedlings.

[0036] Step 2: Adding organic fertilizer, soaking rice seeds to accelerate germination

[0037] In Binhai Lake slurry-type silty land, more than 90% of the soil is sandy substrate, and water and soil will...

Abstract

The invention discloses a rice direct-seeding planting method applicable to coastal mud precipitation type silty saline and alkaline land. The method comprises the steps as follows: step 1, ploughingand field soaking with freshwater to wash salt and reduce alkali; step 2, application of organic fertilizer and rice seed soaking for germination acceleration; step 3, seeding after rotary tillage andleveling; step 4, later field management. A tractor driven rotary cultivator and a tractor driven leveling machine are adopted, the suspension blending amount of mud precipitation type silt is increased through turning and rotating of the rotary cultivator, mud suspensions are treated and stirred by the leveling machine, and rapid separation of water from soil is prevented. Then, a tractor drivenseeding and fertilizer broadcasting integrated machine is adopted to seed germination accelerated rice seeds before separation of mud, the rice seeds are covered with suspended muddy soil, normal seedling erection after rice direct-seeding planting in the mud precipitation type silty saline and alkaline land is realized and the lodging resistance capability of rice seedlings is improved.

Description

technical field [0001] The invention relates to a method for sowing rice, in particular to a method for direct seeding and planting of rice suitable for Binhai lake-type silty sandy saline-alkali land. Background technique [0002] Due to the extremely low soil organic matter content and no formation of soil aggregate structure, the Binhai lake slurry-type silty saline-alkali land has poor tillability. After rotary tillage, it is not easy to pulp and settle very quickly. In extreme places, it will be completely hardened after half an hour after water rotation. [0003] At present, the conventional rice sowing techniques used in Binhai lake-type silty saline-alkali land mainly include artificial transplanting, machine transplanting, water direct seeding, dry direct seeding, etc., but seedling planting is difficult and the survival rate is low; direct seeding cannot be pulped due to rotary tillage , the seeds are exposed on the ground after sowing, without effective coverage...
