Embodiment 1

[0010] The following steps are taken for the method of increasing moisture storage in dry-land wheat fields during summer cultivation: a. The height of wheat stubble remaining during mechanical harvesting is 28cm-30cm, and the harvested wheat straw is evenly scattered on the surface of the wheat field. 120-130kg; b, deep plowing on August 8, the plowing depth is 25cm-28cm; c, when deep plowing, apply diammonium phosphate containing 7.5kg phosphorus pentoxide per mu; d, August 1 When the daily weed coverage rate in the field is 13%-14%, use 200mL of 20% paraquat water agent in time, and spray 40kg of water evenly to carry out chemical weeding to reduce soil water consumption.

[0011] When wheat was sown on September 28, soil samples were collected layer by layer with soil auger using the 5-point method, and the soil water content of each layer was measured with the aluminum box drying method, and the total water storage capacity of the soil within 200 cm was calculated. The re...

Embodiment 2

[0013] The following steps are taken in dry land wheat field cultivation to increase moisture storage: a. During mechanical harvesting, the height of wheat stubble is 25cm-26cm, and the harvested wheat straw is evenly scattered on the surface of the wheat field, and the amount of wheat straw thrown back to the field per mu is 150 -170kg; b. On August 16, carry out deep plowing with a plowing depth of 28cm-30cm; c. During deep plowing, apply diammonium phosphate containing 7.5kg of phosphorus pentoxide per mu; d. On August 5 When the coverage rate of weeds in the field is 12%-13%, use 150mL of 20% paraquat water solution in time, and evenly spray 40kg of water to carry out chemical weeding to reduce soil water consumption.

[0014] When the wheat was sown on September 28, the soil samples were collected in layers with the soil drill by the 5-point method, and the soil water content of each layer was measured by the aluminum box drying method, and the soil water storage within 20...

Embodiment 3

[0016] The method for increasing storage and moisture storage in a dry wheat field during summer cultivation takes the following steps: a. When mechanically harvesting, the height of the wheat stubble is greater than or equal to 27cm-29cm, and the harvested wheat straw is evenly scattered on the surface of the wheat field, and the wheat straw is thrown back to the field per acre. Amount of 220-230kg; b. Deep plowing was carried out on August 23, and the plowing depth was 28cm-30cm; c. When deep plowing, apply monoammonium phosphate containing 8kg of phosphorus pentoxide per mu; d. July 20 When the daily field weed coverage rate is 15% or the weed coverage rate is 7%-8% on August 10, use 200mL of 20% paraquat water solution in time, and evenly spray 40kg of water for chemical weeding to reduce soil water consumption.

[0017] When the wheat was sown on September 27, the 5-point method was used to sample every 20cm layer with a soil drill, and the water content of each layer was ...

Abstract

The invention particularly relates to a water storage increasing and moisture storing method for dry land wheat field mid-summer cultivation, and the problems that because traditional intensive and meticulous cultivation can not be adopted for an existing dry land wheat field, the planting quality is poor, and the yield is low are solved. The method includes the following steps that a, wheat stubble with the height of 25 cm-30 cm remains in the mechanical harvest process, harvested wheat straws are evenly thrown on the surface of the wheat field, and the wheat straws returned to the field through throwing are 120 kg-350 kg per mu; b, soil is ploughed deeply with the plough depth of 25 cm-30 cm from August 8th to August 23th; c, in the deep ploughing process, monoammonium phosphate or diammonium phosphate containing 7 kg-8 kg of phosphorus pentoxide per mu is applied; d, when the weed coverage rate in the field after wheat harvest before deep ploughing is 12-15%, or the weed coverage rate seven days before wheat seeding after deep ploughing is larger than 5-8%, a sterilant herbicide is used for chemical weeding in time, or weeds are extirpated manually in time, and therefore water consumption of the soil is reduced. According to the water storage increasing and moisture storing method, the effect of soil water storage capacity is improved obviously, planting benefits are improved, and rural income is increased.

Description

technical field [0001] The invention relates to a technology for increasing storage by agricultural plowing, in particular to a method for increasing soil water storage by plowing and plowing and fertilizing time in dryland wheat fields during the summer season. Background technique [0002] Dryland wheat plays an important role in wheat production in the central and western regions of my country. Dryland wheat has no irrigation conditions, and the water needed for wheat growth is completely dependent on natural precipitation. The annual rainfall in central and western my country is 400-600 mm, and the distribution is uneven in time and space. It is mainly concentrated in July-September, accounting for about 60% of the annual rainfall. The rainfall during the wheat growth period is only 160 mm from late September to early June. -200mm. Insufficient total natural precipitation, uneven time distribution, and large evaporation and dissipation are the main factors restricting t...
