Paddy rice broad-width direct seeding and simultaneous seeding fertilizing method

Abstract

The invention provides a paddy rice broad-width direct seeding and simultaneous seeding fertilizing method. According to the paddy rice broad-width direct seeding and simultaneous seeding fertilizingmethod, paddy rice seeds with husk broken white part exposure and a controlled-release fertilizer are subjected to seeding and fertilizing using a special direct seeding paddy rice simultaneous seeding fertilizing machine so as to obtain seed rows and fertilizer rows, wherein the seed rows and the fertilizer rows are strip shaped parallel lines, the row distance of the seed rows is controlled to be 18 to 32cm, the seeding width is controlled to be 5 to 15cm, the fertilizer rows are arranged between each pair of adjacent seed rows, and one fertilizer row is shared by two seed rows; in seeding of paddy rice seeds, concave seeding strips with a width of 5 to 15cm and a depth of 2 to 4cm are formed on wet soil surface via pressing, and the paddy rice seeds are placed at the bottoms of the concave seeding strips with a distance ranging from 2 to 4cm from the soil surface to the seeds. The paddy rice broad-width direct seeding and simultaneous seeding fertilizing method is capable of realizing simultaneous seeding and fertilizing, so that plantation efficiency is increased; paddy rice row distance and seeding width are increased appropriately, so that ventilation light transmittance is improved, photosynthesis is promoted, excellent plant growth states are achieved, and colony quality is high; resin-coated urea is adopted to supply 30 to 90% nitrogen, so that seed and seedling burn caused by high fertilizing amount is avoided; the fertilizing depth is controlled to be high, so that nitrogen phosphor potassium utilization rate is increased, and direct seedling paddy rice lodging resistance is improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for live-seeding rice in wide strips and simultaneously sowing seeds and fertilizers. Background technique [0002] As one of the rice planting methods in China, direct-seeding rice is a traditional rice cultivation technique in China, but the planting area has always been small. Since direct seeding rice can be directly spread, eliminating the need for seedling raising and transplanting, it has low labor requirements, and has the characteristics of saving labor, labor, and cost. It is a planting mode that is more suitable for large planters. a rapid development trend. However, there are also some problems in direct-directed rice planting: traditional direct-directed rice planting is artificial seeding, the distribution of rice seeds is uneven, the growth of individual plants varies greatly, and the yield is unstable; Sprinkle on the soil surf...

Problems solved by technology

However, there are also some problems in direct-directed rice planting: traditional direct-directed rice planting is artificial seeding, the distribution of rice seeds is uneven, the growth of individual plants varies greatly, and the yield is unstable; Sprinkle on the soil surface, causing serious nutrient loss; both rice seeds and fertilizers are applied on the soil surface, the root system of rice plants is shallow, the soil is not deep, and the rice stems are prone to lodging; in order to avoid burning seedlings and the need for fertilizer in the middle and late stages of rice growth Requirements, need to topdress many times, labor-intensive and time-consuming

However, the live broadcast method of this patent is dry hole live broadcast, and compared with strip live broadcast, there are some problems such as deep sowing of some seeds, low emergence rate, crowded seeds, affecting individual growth quality, etc., and the hole live broadcast machine is expensive , the equipment is easy to break during use, and the cost of use and maintenance is high
