Embodiment Construction

[0016] A paddy field in Hainan Province belongs to sandy soil with low organic matter content, severe water and fertilizer loss, poor comprehensive fertility, and low rice yield. In June-August after harvesting early rice, high temperature and rainy, many diseases and insect pests, generally no crops are planted, and the method of the present invention is used to carry out water-drain rotation and straw returning of Labrador, as follows:

[0017] After plowing and raking at the beginning of June, open a deep ditch (30 cm deep), raise a furrow (6 meters wide), level the furrow surface, and plant planting rows 3 at a distance of 50 cm in the direction parallel to the drainage ditch 2; Apply compound fertilizer (15-15-15) and organic fertilizer (OM ≥ 30%) to the hole successively at an interval of 40 cm, and the application rates are 150 kg / ha and 7.5 t / ha respectively; plant the fertilizer in 5 holes between two litters at an interval of 40 cm 2 Labrador bean seeds 4, cover soil...

Abstract

The invention discloses a dolichos lab lab irrigated land and dryland crop rotation and straw recycling soil modification method. Crop rotation of dolichos lab lab is performed in a paddy field and straw recycling of the dolichos lab lab is performed in slack season of about 1-2 months in summer. The method includes the following steps of soil preparation, fertilizer application, sowing, field management (water spraying, weeding and diseases and pests controlling) and straw recycling. Practice shows that by means of the dolichos lab lab irrigated land and dryland crop rotation and straw recycling soil modification method, one more season of dolichos lab lab can be harvested, soil fertility modification can be effectively achieved, soil physical properties of the paddy field can be improved, comprehensive soil fertility is improved, and yield and benefit increasing of aftercrop paddy rice can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for planting Labrador in water and dry rotation and returning straw to field for soil improvement. Background technique [0002] After retrieval, there are 4 Chinese patent applications related to Raba bean, involving planting Raba bean to produce silage and replacing Eupatoria adenophorum, but there is no research report on using it to improve soil and fertilize. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for water-drain rotation planting of Labrador bean and a method for returning straw to field to improve soil with excellent effect. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: planting of Laba bean in water and dry rotation and the method of returning straw to the field to improve the so...
