Abstract

A non-ploughing seedling throwing technique for cultivating early or late rice includes such steps as killing weeds, composting green fertilizer, irrigating, applying fertilizer and throwing rice seedling. Its advantages are comparable yield, low cost and less water consumption.

Description

Late rice tillage free throwing culture early,

Technical field: the present invention relates to the plant cultivation field, relate in particular to morning, late rice tillage free throwing seedling technique.

Technical background: traditional morning, late rice are cultivated technology, and before rice transplanting or rice transplanting, need to plough, harrow a field etc. ploughed kind of a measure, and water consumption is many, labour intensity is big, production cost is high.

Summary of the invention: purpose of the present invention just provide a kind of tillage free early, the rice cultivation technology.The present invention is on the throwing seedling technique basis of traditional culture technique and popularization in recent years, carries out morning, the cultivation of late rice tillage free.

Concrete operations technology is as follows:

1, early rice free-plowing and throwing rice seedling: the rice field behind results first crop crop, earlier with the steriland herbicide plant of cutting weeds of going out, after breaking withered green manure weeds with medicine, irrigation fertilization, fertilizing amount is carried out by the existing conventional fertilizing amount in batches, generally carrying out in preceding 15 days at rice transplanting, can not dewater in the later stage rice field, in order to avoid cause field piece soil compaction.

2, late rice free-plowing and throwing rice seedling: when early rice is gathered in, stay stump as far as possible, straw can not all be sprinkling upon Tanaka, but in order to increase organic manure, 1/3 straw can be cut short (10-15 centimetre) and be sprinkled into Tanaka, pour water, apply fertilizer, go out with steriland herbicide simultaneously and cut weeds and the premature rice seedling, break withered rice stub, straw and weeds, also can add and spread quicklime and ash with medicine, impel rice stub, straw and weeds to quicken to rot, be beneficial to late rice and throw to plant and take root.Late rice seedling dish will be used macropore seedling dish, and the seedling order can reach 25-30 days, because the rice shoot of macropore seedling dish is sturdy, rice shoot is big, and root system band mud is many, and throwing is planted the land for growing field crops and easily taken root, and is beneficial to survive.

The present invention can save nearly 80 yuan/mu of cultivated land cost owing to exempted cultivated land, harrow a field etc. cultivated measure, saves and ploughs the water 40m that harrows a field ³/ mu, the output of every mu output and traditional cultivation method and the cultivated throwing-seedling cultivation that harrows a field does not have difference.
